algorithm - "cycles per byte"对算法的性能意味着什么？

Question

算法性能的“每字节周期数”是什么意思？

Answer 1

来自 Wikipedia :

Cycles per byte (sometimes abbreviated cpb) is a unit of measurement which indicates the number of clock cycles a microprocessor will perform per byte (usually of octet size) of data processed in an algorithm. It is commonly used as a partial indicator of real-world performance in cryptographic functions.

(number of processors × processor_utilization × processor clock frequency) / Throughput rate in bytes per second or transaction per second = cycles per Byte or transaction.
