GitHub - gwsystems/aWsm: WebAssembly ahead-of-time compiler and runtime. Focuses on generating fast code, simplicity, and portability.
aWsm is a compiler and runtime for compiling WebAssembly (Wasm) code into llvm bytecode, then into sandboxed binaries you can run on various platforms. It focuses on generating very fast code (best of breed for WebAssembly), having a simple and extensible code-base, and on portability. What is WebAssembly? Wasm is a standard binary format that is platform agnostic, debuggable, fast, and safe. Plea
TensorFlow Lite for Microcontrollers
TensorFlow Lite for Microcontrollers is designed to run machine learning models on microcontrollers and other devices with only a few kilobytes of memory. The core runtime just fits in 16 KB on an Arm Cortex M3 and can run many basic models. It doesn't require operating system support, any standard C or C++ libraries, or dynamic memory allocation. Why microcontrollers are important Microcontroller

perfから読み解くプロセッサトレースの仕組み (perf + Intel PT/ARM CoreSight) - Qiita
諸事情でperfのソースコードを読んだのでせっかくなので簡単に解説。 今回はperfの中でもイベントの記録を担当するperf recordコマンドの処理を見ていく。特に近年はCPUがトレース機構を持っておりperfもその恩恵に預かっているため、本記事ではperf recordの中でもCPUのプロセッサトレース機構との連携部分に注目したい。 本音を言えば、perfよりIntel Processor Trace(Intel PT)やARM CoreSightといったプロセッサトレース自体に興味があるのだが、これらはLinux上ではperfイベントとして実装されているためperfコマンドの実装を皮切りに解析する腹づもりだ。 1. Perf アーキテクチャ 元々perfはPerformance counters for Linux (PCL)という名前の前身が存在しており、CPUの提供するパフォー
Low-Level Software Security for Compiler Developers
1 Introduction Compilers, assemblers and similar tools generate all the binary code that processors execute. It is no surprise then that these tools play a major role in security analysis and hardening of relevant binary code. Often the only practical way to protect all binaries with a particular security hardening method is to have the compiler do it. And, with software security becoming more and
CH32F103C8T6やCS32F103C8T6とは
みんな大好きblue pill STM32の激安開発ボードと言えば、そう、blue pillがありますね。32bitマイコンのSTM32F103C8T6が載っているのに格安の1～2ドルで大変重宝していました。亜種としてはblack pillとかもあります。 しかし昨今は世界的半導体不足の影響か、Aliexpressでも5ドル以上と、お手軽さがなくなってしまいました。そこでショップ側も対策すべく、STM32と並んで、CH32F103C8T6が載ったblue pill的なもの(type-Cにアップグレードされていることが多い)を3ドル程度で売っているのをよく見るようになりました。ではこのCH32F103C8T6とは何なのでしょう。コピー品 STM32には昔からコピー品(クローン品)があります。困ったことにシルク印刷が「STM32」表記のままの劣化コピー品が出回
My Business Card Runs Linux
Of course, there are other costs that are difficult to quantify like shipping (since it’s spread across multiple projects). But this is definitely pretty cheap for a Linux board. It also gives a pretty decent starting point for quantifying how much it costs companies to manufacture bottom-end devices: you bet they’re getting everything even cheaper than I am! Capabilities What can I say? It boots
