DM8148 Rare to Riches

You can influence your happiness in a multitude of ways. It's the totality of all you think, do and experience. "Hardship builds strength of character and toughness."; so, happiness is closely related to a hopeful, acceptance of life's challenges. What works? In the 1970s, researchers followed people who'd won the lottery and found that a year afterward, they were no happier than people who hadn't. This is called

hedonic adaptation

which suggests that we can expect to return to a baseline level of happiness. No matter what events occur, good or bad, the effect on ones happiness is temporary, and happiness tends to quickly revert to the baseline level. Some people have a higher baseline happiness level than others, and that is due in part to genetics, but it's also largely influenced by:

.

Accumulate all the little DM8148  things that happen to you during the day. They add up. You could keep a journal, and write them down. For example, if there was not bad traffic on the road, if you had a very scrumptious breakfast, if your friend said something uproariously humorous that made you laugh, if you took your dog out for a walk in the park and played with it, add these together. Your outlook can begin to brighten.

Think deeply grateful thoughts for the things you have. This is a very effective way to become more happy. If you feel grateful for the things you have, you not only become more happy, but it also helps you to bring more good feelings into your life.

View the glass as half-full instead of half-empty. Your girlfriend/ boyfriend broke up with you? Now you have the chance to meet someone good for you! You lost your job? Now you can seize the opportunity to find a better one! Adjust your mentality so that, in each thing that happens, you see some kernel of good, and say hopeful words, "It will be all right!", or "It's going to be good.", or "I'll keep expecting good results."

DM8148  1000MHz ARM / 750MHz DSP

As I check with TI DM8148 wibsite, we know TI has TMS320DM8148CCYEA0 ( ARM:720 Mhz, DSP: 600Mhz, Extended temp).

But, will TI plan to release DM8148 that is 1000MHz ARM / 750MHz DSP with Extended temperature?

The current plan is to support Extended temp option with speed grade 0 (i.e., TMS320DM8148CCYEA0) only. There is no committed plan to supporting extended temp devices in other speed grades

I was hoping to verify some part numbers/availability of industrial temperature versions (or extended if industrial is not available) of some of these next generation TI processors.

Here is what I have found via datasheets/other means, could a rep from TI please verify all of these part numbers are correct and currently order-able?  I am trying to do some comparisons to determine which processor we want to use and I need to verify the processors are available in industrial/extended temperature.

Setup and build RC and RP

We have already gone through this link and have not found anything that can help us. This link just describes how to setup and build RC and RP sample applications.

The question I want to ask is this:

Assuming that our RC driver enumerates and maps end point devices correctly. Our eDMA implementation is also tested on memory to memory transfers. So in this case, if eDMA reads/writes over PCI Express memory don't work correctly, then where could be the issue? eDMA side or PCI Express root complex side driver?

So, far we have not seen any functional issue with RC driver, except the DMA transfers. So what could be possibly wrong here? and what could be the right direction to explore this issue?

We are using FPGA based DM8148 memory controller as an EP.

Are the start and end of your transfers 16-byte aligned (per errata advisory 3.0.6) ?

Also, be sure to check the EDMA TC used for transfer errors:  if a problem occurs with the read, the write is not aborted but will write zeroes instead.

I have again verified DM8148 16 byte alignment at start and end of transfers. This doesn't resolve our issue.

As a first step we are only focusing on EDMA writes to PCI-E memory while verifying the data back using CPU reads from PCIE memory. EDMA write transfer doesn't update memory contents of EP. I have checked error status in EDMA TC, all the following error registers read zero after the transfer completion interrupt of write transfer is received. So, there seems to be no error in EDMA write transfer.

Error Register (offset 0x120) : reads all 0

Error Details Register (offset 0x12C) : reads all 0

Error Interrupt Command Register (offset 0x130) : reads all 0

The Interface of DM8148

The interface of DM8148 and USB I used, when configured to host it function determines, when I as the configuration storage devices on the same port (USB0), no detection of PC.

And the kernel of the cofiguration, I run in the EVM board is detected when the USB storage device.

A kernel / between the u-boot version and little difference, mainly in the pinmux configuration, but the USB drive is the same.

The EVM uses different cable (micro B plug) from and custom circuit board (standard type B) for use in.

We also observed and scope, in the D + and D- pin signal, but there was no signal in the custom circuit board.

We do not know how to debug the problem.

DSP Library Programmer's Reference Guide

I implemented LU decomposition algorithm to find the inverse of a 36 x 36 complex matrix (In turn I had to convert this in to a 72 x 72 matrix before I could pass it to the matrix inverse algorithm). This is increasing the CPU cycles required for the computation and hence my C - code is not meeting the time requirement.

I was wondering if there is any DSP like DM8148 library function available to find the inverse of a complex matrix? I checked the forum but couldn't get much help.

If there is no such library function available for CCS, I would appreciate if somebody can guide me towards better complex matrix inverse algorithms or ideas.

Refer to Single precision DSPF_sp_lud_inv_cmplx and Double precision DSPF_dp_lud_inv_cmplx functions in the DSP library version 3.4.0.0.

Is there a DSP Library programmer's reference guide document available for this 3.4.0.0 version?

The documents included in the DSP library installer with user manual in doxygen form.

DM8168 has 3 HDVICPs support h264 and Mjpeg

Using DM8168 to get it's image size(3200x2400) DM8168 cant support 3200X2400, you can look for DM8148 where ISS can support in terms of Mega pixels.

I have few technical queries with respect to DM8168 and also on other DMxx parts.

Request you to clarify my below queries.

For the below parts ie..

1. DM8168

2. DM8127

3. DM388/DM385

All these parts falls under same family, but not sure whether the below requirements are met by all these parts:

1. Required is 12MP camera interface. But what is the max. resolution camera can be interfaced to all of the above TI parts.?

2. What is the maximum resolution camera still image can be stored in SD card?

3. whether camera video streaming and HDMI display without storage is 1080p @ 60fps.

4. whether camera video stored in SD card in H.264/MJPEG is 1080p @ 60fps.

5. whether stored camera video in H.264/MJPEG is played on HDMI with 1080p @ 60fps.

There is limits theoretically, depends on the device/port but the actual max resolution is not verified. Would you provide the width/heighth you want and I will try to check if it is ever verified ?

I don't think there is limitation on this. what you need to taken care is the data rate of the SD port.

For each device we have documents talking about the performance of each use-case. For the devices you listed, they all meet this requirement.

About DM8127/DM385, For either H264 or MJPEG there performance can reach 1080p60, but can not do together for 60. 30fps is possible.

For DM8168, because it has 3 HDVICPs, it can support h264 and Mjpeg both 1080p60

Yes , supported.

DSP AND CCS Development

Embedded ProveID support TI DM8148 SoC and RDK, and directly integrated thin passenger side - and zero client solutions, providing local certified software layer. In addition to supporting rapid and safe data access, provides the flexibility to provide manufacturers and end users, and to ensure that the technology will provide long-term investment value and simplify management.

Grew by 44% in the prediction of desktop virtualization application in 2013, such as a hospital, a company in need of a relatively strong authentication, DM8148 users can click from any access, this is who need immediate access to the protected clinical data service provides the necessary benefits.

A) certain files or data of IPC can only be used between the application programs to run BIOS forcommunication, there are some information for reference of the IPC can, in some cases, royalties, ARM side sometimes, how do you understand?

B) some of the established 2 seems to cannot use the IPC template project, loaded into DSP will run to fly. DSP and ARM could not be under the guidance of how to communicate, how to establish the correct sample project?

At present, the study of communication between DSP and ARM. Look at some of the user manual, some projects by CCS V5 built-in, have the above problems

To be clear, we used the DM8148 synchronization with VGA analog domain of discrete signals, and tries to make a 16-bit synchronous signal out TVP7002 embedded in the discrete domain. Using external chip of EVM entry and add some code programming, we can capture from VGA input 1080 p and 720 p. Now, we are changing our hardware, and see if we have a hardware problem.

[dm8148-evm]

DM8148 and New Analogs

To clarify some terminology of how DM8168 and DM8148 and its previous development tolls since it is getting confusing.

In the analog domain the terms are SoG (sync on green) to mean that the sync signal is combined with the Y channel or green channel. The term separate syncs is used to indicate that there are individual 'analog' signals for H & V sync.

In the digital domain the term embedded syncs means that the start of active video and end of active video codes are embedded in the digital color data streams. Discrete syncs means there are individual digital signals for each of H, V and where necessary FID.

Analog VGA virtually NEVER uses SoG syncs anymore and pretty much is always separate syncs.

Analog YPbPr virtually ALWAYS uses SoG. I have never seen separate syncs for YPbPr.

In the digital domain for DM8148  video applications (i.e. YPbPr analog video) you should use digital YUV 422 output. Embedded syncs is easier and more common but discrete is OK too.

Digital VGA should ALWAYS be 24 bit discrete syncs. Using embedded syncs reduces the dynamic range. Using 16 bit 422 completely destroys color sharpness and converting from RGB to YUV kills color fidelity.

The DSP Development Platforms

In the development of image taking and then face recognition, application of criminal suspects bank ATM, identification, the main consideration is the TI Da Vinci series products, of which, if you want to select HD material input, should be the first choice of DM8168 series.

Is composed of independent research and development of non development Mdt InfoTech Ltd fan extensible computer (EMA) of Guangzhou yard, adopt the latest Intel Atom processor E3800 chip (SoC), computing, image processing to improve performance and reduce power consumption, the considerable advantage. In view of things (Internet of things), intelligent application industry vigorous development of the Internet.

TI DM8168 has the advantages of high performance, low power consumption, and make it become the machinery automation, intelligent transportation, vehicle safety monitoring, marine and energy related application preferred.

The performance of DM8168 can be extended to computer calculation, and without the fans is excellent, low power consumption and excellent performance, and the Intel 7 generation graphics graphics functions, greatly improving the graphics and media processing performance. In addition, 2 isolated CAN bus built-in, segregation of digital I / O, the communication system and equipment room is more convenient, reliable. Characteristics of DM8168 series products with flexible expansion, I / O interface, to provide a variety of different criteria.

Therefore, according to:

the demand elasticity and the configuration;

performance;

application specific good scalability;

wide temperature users can;

provides two kinds of embedded intelligent platform reliability and flexibility.

If R & D the difficulty is too large, or a limited budget, want from a simple low cost route development, simplified version of the DM8148 is also a good choice, will not reduce the imaging effect, but will save the cost.
