Abstract
A data processing system using a main processorand a coprocessorprovides coprocessor load instructions (USALD) for loading a variable number of data values dependent upon alignment into the coprocessorand also specifying data processing operations to be performed upon operands within those loaded data words to generate result data words. The specified coprocessor processing operations may be a sum of absolute differences calculation for a row of pixel byte values. The result of this may be accumulated within an accumulate register. A coprocessor memoryis provided within the coprocessorto provide local storage of frequently used operand values for the coprocessor
