Unusual circuits in the Intel 386's standard cell logic

I've been studying the standard cell circuitry in the Intel 386 processor recently. The 386, introduced in 1985, was Intel's most complex processor at the time, containing 285,000 transistors. Intel's existing design techniques couldn't handle this complexity and the chip began to fall behind schedule. To meet the schedule, the 386 team started using a technique called standard cell logic. Instead of laying out each transistor manually, the layout process was performed by a computer.

The idea behind standard cell logic is to create standardized circuits (standard cells) for each type of logic element, such as an inverter, NAND gate, or latch. You feed your circuit description...

Pocket8086 – An handheld x86 retro computer with an XT-class 8086/V30 CPU running DOS 6.22 or Windows 3.0

The Pocket8086 is a handheld retro computer built around classic 8086, 8088, NEC V20, or NEC V30 processors, giving it the performance and behavior of an 8086-class retro computer while still offering the convenience of a compact handheld form factor. Designed for vintage-computing enthusiasts, DOS gamers, and makers, it delivers a handheld retro computing experience suitable for DOS 6.22 as well as Windows 3.0/3.1, effectively packing an XT-class machine into a portable device. The device integrates a 4.77–10 MHz CPU, 768 KB RAM, a replaceable TVGA9000i-based VGA card with 512 KB VRAM, OPL3 (YMF262) audio, a built-in mouse, PS/2 support,...

Air Lab is the Flipper Zero of air quality monitors

Air Lab is the Flipper Zero of air quality monitors

This air quality monitor costs $250. It's called the Air Lab, and I've been using it to measure the air in my car, home, studio, and a few events over the past few months. And in using it over the course of a road trip I learned to not run recirculate in my car quite as often—more on that later.

«Фамипия». Венгерские домофоны в подъездах Питера

Приветствую всех!
Уверен, многие видели на стенах старых домов эти штуки - довольно большие серебристые или цветные панели с кучей кнопок на них. Сейчас практически все они давно разбиты или выдраны, однако те, кто постарше, возможно, даже успели застать их рабочими. И нет, никаких фамилий там нет: называлась эта панель именно так.

И, хотя рабочих таких домофонов уже нигде нет, мне всё же удалось заполучить один умеренно целый экземпляр. Так что сегодня у нас есть уникальный шанс ознакомиться с его схемой и начинкой и увидеть этот артефакт восьмидесятых в работе.

Ridiculously tiny ESP32-C3 board features USB-C, one LED, and a ceramic antenna

PegorK’s f32 might be the world’s smallest ESP32-C3 board. It measures just 9.85 x 8.45 mm, or slightly larger than the area covered by a USB Type-C connector. A board of this size will have limited features, and besides the ESP32-C3FH4 RISC-V WiFi and Bluetooth microcontroller, it comes with a USB-C port, a ceramic antenna, and a single GPIO pin connected to an LED. f32 specifications: SoC – Espressif Systems ESP32-C3FH4 Single-core 32-bit RISC-V microcontroller @ up to 160 MHz Memory – 400 KB SRAM Storage – 4MB flash Wireless 2.4 GHz Wi-Fi 4 & Bluetooth 5.0 USB – 1x...

AOMedia AV2 open video codec release nears, delivers around 40% bandwidth reduction

The Alliance for Open Media (AOMedia) will release the AV2 open video codec specification by the end of the year, as an update of the now widely-used AV1 video codec with up to 40% bandwidth reduction at the same level of quality. In the meantime, Debargha Mukherjee, Google Principal Engineer, has shared a progress report about AV2, first offering a historical perspective with the list of digital video codecs from 1990 to 2030 (expected), then stating AV2 goals, and going through requirements, coding tools, and what’s been achieved so far. You can check the eleven-minute presentation (04:27 – 15:30) embedded...
