ABSTRACT:
A data processing system using a main processor8and a coprocessor10provides coprocessor load instructions (USALD) for loading a variable number of data values dependent upon alignment into the coprocessor10and 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 register22. A coprocessor memory18is provided within the coprocessor10to provide local storage of frequently used operand values for the coprocessor10.
