    Fast Base64 stream encoder/decoder This is an implementation of a base64 stream encoding/decoding library in C89 with SIMD (AVX2, NEON, AArch64/NEON, SSSE3) acceleration. It also contains wrapper functions to encode/decode simple length-delimited strings. 4/8/2016 · Instruction Set Architecture • Describes how processor processes instructions • Makes available instructions, binary codes, syntax, addressing modes, data formats etc. • ARM defines two separate instruction sets o ARM state instruction set – 32-bit wide o Thumb state instruction set – 16-bit wide N. Mathivanan 3.

    The ARM instruction set has increased over time. Some early ARM processors (before ARM7TDMI), for example, have no instruction to store a two-byte quantity. Pipelines and other implementation issues. The ARM7 and earlier implementations have a three-stage pipeline; the stages being fetch, decode and execute. Higher-performance designs, such as A superscalar complex instruction set computer (“CISC”) processor having a reduced instruction set computer (“RISC”) superscalar core includes an instruction cache which identifies and marks raw x86 instruction start and end points and encodes “pre-decode” information, a byte queue which is a queue of aligned instruction and pre-decode information of the “predicted executed

The Mill architecture employs a unique split stream instruction encoding that enables sustained decoding rates of over 30 operations per cycle by being wide.

    I've been going through ARM ISA related documentation since a while and so far I believe that I've got a good understanding for the basics of ARM/Thumb interworking. I'll quickly summarize that in 1.1 The Reduced Instruction Set Computer RISC architecture In 1980 Patterson and Ditzel published a paper entitled 'The Case for the Reduced Instruction Set Computer'.
