If separate hardware units carry out these activities their operations can be overlapped to give an increased rate of completion of instructions. This technique, first introduced in computers such as Atlas and Stretch, has become known as . In a pipelined co

This problem also impinges on instruction accessing, since for efficient operation instructions must also be supplied to the processor at a rate matching its execution rate. In the case of instruction accessing, however, the problem is ameliorated by the fact that most instru

In the case of the CDC 6600, performance was the principal criterion of the design, and as we saw in chapter 2, the use of parallel functional units with an instruction set capable of explo

In practice,

Thus a data structure as seen by the programmer is broken up into small sections and mapped into the vector registers by software. In machines which process the programmer’s data structures more directly, a number of quite different problems

Knowledge about such aspects of their design, together with knowledge about the clock periods of these machines, provides a limited picture of their performance potential. For example, before spending several mi
