Abstract

The error sources in a high accuracy optical matrix-vector processor are analyzed by numerical simulation in terms of their effects on the parallelism and speed of the processor. These effects are detailed for radices −2, −4 and −8. Radix −4 is shown to provide maximum parallel processing capabilities under the effects of the system’s error sources. Processing speed is shown to be a function of matrix partitioning and the number of parallel processing channels. Consequently, radix −4 operation provides a higher processing speed than radix −2 and −8 for most matrix-vector multiplications when error source effects are considered.
