Abstract
A microcomputer prioritizes data operand requests and instruction prefetch requests. Such prioritizing is established by established criteria. The established priority is altered upon the occurrence of a signal. The signal indicates a certain type of data requests. This data request type is deemed to have a higher priority than is typical for a data request. Consequently, in response to receiving the signal which indicates this data request type, the priority is altered so as to be more inclined to perform the data request. This is particularly useful when performing numerous consecutive data operations, such as a co-processor interface operation.
