Jeff Bezos Backs Tenstorrent in $700M Bid to Challenge Nvidia’s AI Chip Dominance.

Jeff Bezos Backs Tenstorrent in $700M Bid to Challenge Nvidia’s AI Chip Dominance. Nvidia’s dominance in the artificial intelligence (AI) chip market is under fresh scrutiny as Tenstorrent, a Santa Clara-based startup, secures a $700 million funding round backed by Amazon founder Jeff Bezos through Bezos Expeditions. Valued at $2.6 billion, Tenstorrent aims to disrupt Nvidia’s near-monopoly with…

ESP32-C3 BLE / WiFi dev board with 0.42-inch OLED notes

I got some ESP32-C3 dev boards with built-in OLED screens for a Halloween costume project, and I've been troubled by the lack of documentation and general information about both the ESP32-C3 platform and the board, so here are some notes for future hackers:

OLED type is SH1106, not SSD1306, as seen in some forum posts and even in the blurry screenshot that accompanies these boards. Specifically, the U8G2 constructor for this board is U8G2_SH1106_72X40_WISE_F_HW_I2C(). With the SSD1306 driver, the screen pixels are shifted to the left and there's a column or two of corrupted data on the right-hand-side of the OLED screen.

Apparently the ESP32-C3 chip cannot measure its supply voltage internally, something that even ATtiny chips can do :(

Proper Arduino configuration is:

(CPU frequency and partition setup are of course configurable).

I'm not sure yet if I2C is actually hardware-offloaded here, but the pins are apparently non-default, with SDA=5, SCL=6. At least the display speed doesn't change at all when changing the I2C frequency. I don't have the equipment to measure this, but so far it looks like I2C clock speed is ignored. Anyway, I can get about 73 FPS, or about 11ms per frame draw on the built-in 72x40 OLED.

But overall, looks like a nice dev board, and it's neat that it's powered by a RISC-V microcontroller. Perfect for hobby projects that don't need many pins.

Buy the board here.

Risc-V işlemcili yeni sistem: Milk-V Jupiter

Liliputing kaynağına göre Shenzhen MilkV Technology (Milk-V) şirketi, RISC-V mimarisini temel alan bir işlemciyle donatılmış Jüpiter adlı bir kartı piyasaya sürmeye hazırlanıyor. Yeni ürün, Mini-ITX standart boyutuna sahip ve bu da onu çeşitli kasalarla uyumlu hale getiriyor. Ürünün boyutları 170×170 mm’dir. Değişikliğe bağlı olarak, RISC-V tabanlı sekiz SpacemiT X60 çekirdeğine sahip bir SpacemiT K1 veya M1 işlemci kullanılıyor. Çip, bir Imagination BXE-2-32 grafik hızlandırıcı ve 2 TOPS'a kadar performansa sahip bir AI işlem birimi (NPU) içeriyor. LPDDR4x RAM miktarı 4, 8 veya 16 GB olabiliyor (karta lehimli, bu da yükseltme olasılığını ortadan kaldırıyor). PCIe 2.0 x2 arayüzlü M.2 2280 SSD için bir konektör ve microSD kart için bir yuva mevcut. Ayrıca bir eMMC çipi de eklenebiliyor. GPU'lar veya ek SSD'ler gibi genişletme kartları için bir PCIe 2.0 x8 yuvası da bulunuyor. Wi-Fi 6 ve Bluetooth 5.2 kablosuz iletişim desteklenmekte. Konektör seti, USB 2.0 Tip-C, USB 3.0 Tip-A (×2) ve USB 2.0 Tip-A (×2) bağlantı noktalarını, HDMI arayüzünü (1920 × 1440 piksele kadar; 60 Hz), 3,5 mm ses jaklarını içeriyor (ses çıkışı, mikrofon girişi), ağ kabloları için iki RJ-45 konnektör (1GbE adaptör), güç kaynağı için DC jakı (12 V). Kartın kendisindeki konektörler aracılığıyla iki ek USB 3.0 ve USB 2.0 bağlantı noktasını da kullanabilirsiniz. Diğer şeylerin yanı sıra, CR1220 pil için bir RTC konektöründen ve PWM kontrollü bir fanı bağlamak için bir konektörden bahsedilmektedir. PoE teknolojisi desteği isteğe bağlı olarak mevcut.

The dynamics of open standard technology is such that if President Biden’s administration were to regulate US companies’ participation in the Swiss-based foundation in the way lawmakers are seeking, it would complicate how American and Chinese companies work together on open technical standards. 

Certainly, such measures could obstruct China’s quest for self-reliance in chip manufacturing. But they would also hinder US and European endeavors to create cheaper and more versatile chips.

The question is whether the US can find ways to acknowledge the truth of Rubio’s statement and evolve domestic chip production around it, without shooting itself in the foot over RISC-V.

Hangover 8.19

Вышла новая версия Hangover 8.19, проекта разработчиков Wine, направленного на поддержку работы Wine на процессорных архитектурах, отличных от x86, что в конечном итоге позволит упростить запуск x86/x86_64 Windows-игр/приложений в средах Linux AArch64, POWER и RISC-V. Однако до сих пор основной упор делается на то, чтобы эти Windows-приложения/игры могли работать на системах ARM Linux.
