Agner Fog also doesn't have this function in his `asmlib` (Assembler Library). However, he has some very fast string functions. I'm sure you can use his `strstr()` function and memmove() to do the same as memccpy()! Agner Fog's strstr() should be using SSE2 instructions, so it can compare 16-bytes per read/load.

The new instructions. SSE 4.2 introduces four instructions (PcmpEstrI, PcmpEstrM, PcmpIstrI, and PcmpIstrM) that can be used to speed up text processing code (including strcmp, memcmp, strstr, and strspn functions). Intel had published the description for new instruction formats, but no sample code nor high

Instruction Tables (Intel Skylake ) Branch instructions are problematic: a wrong guess may flush succeeding  Agner Fog compiles very useful tables, based on his own observation of architectures, but these “Instruction Ta- bles” [5] are also incomplete and not easily  Agner Fog is a Danish evolutionary anthropologist and computer scientist.

2014-08-08 · You show this in the instruction tables as 1 uop on Port 0 for 128-bit FP divide and 2 uops on Port 0 for 256-bit divide, but I had not seen anyone comment specifically on the absence of FP divide throughput speedup on AVX before, so I thought I would bring it up. These vary by CPU architecture, but the best resource currently for x86 timings is Agner Fog's instruction tables. Covering no less than thirty different microarchitecures, these tables list the instruction latency , which is the minimum/typical time that an instruction takes from inputs ready to output available. Instruction tables - Lists of instruction latencies, throughputs and micro-operation breakdowns for Intel, AMD and VIA CPUs 4. テクノロジー カテゴリーの変更を依頼 記事元: www.agner.org Agner Fog is known as a "CPU analyst" to tech websites covering x86 CPUs. [2] [4] He maintains a five-volume manual for optimizing code for x86 CPUs, with details on the instruction timing and other features of individual microarchitectures .

Intel flavors often do both with a single idiv instruction. Agner Fog has performance tables for many variants [1]. I’d guess a few pipeline to similar per loop cost of shift and add. I suppose if you’re writing a paper you’re aware of quite a bit of literature on exactly this problem. Recent papers have quite fast methods to do this.

I'm interested in the AVX2 side of this Great news. I have made a new vector class library that makes it easier to use the vector instruction sets from SSE2 to AVX and AVX2.
