On the CPU side, I intended to benchmark as many Pentiums as possible, possibly from 60Mhz (1993) to 223Mhz (1997). I also wanted to see with my eyes the infamous Cyrix 6x86 (1995), and AMD K6 (1997) processors perform.
The aarch64 instruction set has a madd instruction that performs integer multiply-adds. Cortex A725 and older Arm cores had dedicated integer multi-cycle pipes that could handle madd along with other complex integer instructions. Cortex X925 instead breaks madd into two micro-ops, and handles it with any of its four multiply-capable integer pipes. Likely, Arm wanted to increase throughput for that instruction without the cost of implementing three register file read ports for each multiply-capable pipe. Curiously, Arm’s optimization guide refers to the fourth scheduler’s pipes as “single/multi-cycle” pipes. “Multi-cycle” is now a misnomer though, because the core’s “single-cycle” integer pipes can handle multiplies, which have two cycle latency. On Cortex X925, “multi-cycle” pipes distinguish themselves by handling special operations and being able to access FP/vector related registers.
