may be because of the push instructions de-aligning the stack, to make asm source you can actually re-assemble, like Agner Fog's objconv .

Instruction tables: Lists of instruction latencies, throughputs and micro-operation breakdowns for Intel, AMD and VIA CPUs Contains detailed lists of instruction latencies, execution unit throughputs, micro-operation breakdown and other details for all common application instructions of most microprocessors from Intel, AMD and VIA. Agner Fog Research Topics Culture theories interdisciplinary theories of cultural change, including cultural selection theory and regality theory.

requires rewriting instruction tables, resource utilization In this paper we introduce Ithemal (Instruction THroughput similar to Agner Fog's timing script4.

We look at installing the library, as well as an overview of the vector types, Hennessy and Patterson don't cite Fog and that's just crazy.

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.

Table 1. Vector register size of x86 family microprocessors.

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.

Agner Fog's "instruction_tables.pdf" is the most comprehensive single document for latency and throughput, with the added benefit of including AMD (and Via) processors and maintaining all the historical results in mostly the same presentation form. Agner Fog's "microarchitecture.pdf" (https://www.ag

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.

Latency and Throughput of MPX Instructions. The following table shows the latency-throughput results of Intel MPX instructions. For this evaluation, we extended the scripts used to build Agner Fog’s instruction tables. 1 Our scripts can be downloaded here.

Other tested instructions are not eliminated, including adr/adrp, and mov x0, xzr. Complex Latencies. Several instructions have latencies that aren't adequately described in the instruction tables: MADD's output can be passed to its third operand (the addend) with 1c latency, but if it's chained with other instructions it has 3c latency.
