9 cze 2024 · With over 230 billion ARM chips produced, as of 2022, ARM is the most widely used family of instruction set architectures. There have been several generations of the ARM design. The original ARM1 used a 32-bit internal structure but had a 26-bit address space that limited it to 64 MB of main memory. This limitation was removed in the ARMv3 ...
4 dni temu · At its core, WebAssembly is a virtual instruction set architecture (virtual ISA). As such, it has many use cases and can be embedded in many different environments. To encompass their variety and enable maximum reuse, the WebAssembly specification is split and layered into several documents.
1 dzień temu · This project implements a simple assembler for a custom Instruction Set Architecture (ISA). The assembler reads assembly code, processes it in two passes, and outputs the corresponding binary machine code. It supports memory-reference instructions (MRI), register-reference instructions (RRI), and input-output instructions (IOI).
4 dni temu · III-A Instruction Set Architecture (ISA) To add custom instructions on RISC-V ISA to compile, we should first assign the instruction symbol, type, constituents, MASK, and MATCH. MASK is the 32-bit binary to filter out the opcode and functions(e.g., funt3, funct5, funct7, etc). MATCH is the 32-bit binary that contains actual opcodes and ...

ARMv7-A Architecture Reference Manual This has some useful info on what is supported by older architecture versions. ARMv7-M Architecture Reference Manual This covers the Thumb2-only microcontrollers.
5 dni temu · The instruction objects should represent instructions from the architecture manual of the target machine (such as the SPARC Architecture Manual for the SPARC target). A single instruction from the architecture manual is often modeled as multiple target instructions, depending upon its operands.
