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.

The definition of the throughput: is the time in [cycle] to perform a new identical mnemonic. Hmm, no, those latency timings appear to include an L1 access for some strange reason. Which did increase from 2 to 3 cycles. Google "agner fog instruction tables" instead.

Hi, I was wondering what is the latency and throughput of the vbroadcastsd instruction? (This is for Sandy Bridge) I did not find that information in the Optimization Reference Manual. Thanks!

Cycle Count Tool in C Programming. At the very least, your program should output counts for: ADD, SUB, MUL, DIV, MOV, LEA, PUSH, POP, RET. i.e. For your analysis (and

It's a 2-fused-domain-uop instruction that only uses the store-data and store-address ports, not the shuffle unit. (Agner Fog's table lists it as using one p015 uop on SnB, 0 on IvB. Agner runs each platform through a laundry list of micro-targeted benchmarks, in order to suss out details of how they operate. The officially published instruction latency charts from AMD and Optimizing software performance using vector instructions. Agner Fog (Invited speaker) 19 Oct 2016 → 21 Oct 2016. Activity: Interesting that he chooses to mark the first word of an instruction with the size of the instruction rather than to mark each word of an instruction according to whether it's the first word of the instruction or not. Makes the ISA more like DNA which can be read 6 ways, if you don't count stuff like introns and selenocysteine.

For example add m, r (in Agner's tables) or add (m64, r64) on uops.info, or ADD r/m64, r64 in Intel's manual ( https://www.felixcloutier.com/x86/add ). Here's a simple example I ran on godbolt.

The link is presented without commentary, but for those who do not know, Agner Fog manuals are pretty much the bible on x86 microarchitectural details and optimization. salicideblock 45 days ago Indeed.
