AMX for PowerPC Timing Guide

The current release of KADAK's AMX™ Multitasking Executive is the fifth in a long series spanning more than 20 years of development. With AMX coded in C and with the increasing use of RISC processors, kernel timing metrics have become increasingly difficult to define and measure.

It is the purpose of this AMX Timing Guide to provide actual AMX timing information and to introduce the factors which affect these performance figures. Since instruction counts and cycle counts can no longer be used to measure execution times, it is necessary to provide specific measurements and to define, in detail, the conditions under which they were made. The remainder of this chapter will introduce the major factors which make timing measurement so difficult.
