Abstract:

A review is given for a technique that relates the performance of the CPU 1 Main Memory section of small computers to standard design parameters such as wordlength, number of registers, etc. The technique was constructed from execution time and memory space data obtained by applying three small benchmark program kernels to fifteen computers. The data was used to determine regression equations that provide a best fit to the data. Time and space equations were developed for each kernel. Three or four variables from the set of design parameters were used as the independent variables in each equation. These variables were chosen, in each case, as the ones that accounted for most of the variation in the observed data. This report applies these equations to both the ANUYK-20 and ANUYK-7 computers to predict their time and space values with respect to the three kernels. The kernels have been programmed for these two machines and the actual time and space values obtained are compared to the predicted results, as well as to the actual results obtained for the fifteen computers in the original study.
