ABSTRACT:
A computer system which includes a central processing unit including a first processing unit that performs basic processing functions and a co-processing unit that performs multiple specialized processing functions concurrently with the first processing unit, an arrangement for detecting the occurrence of a function causing an exception in a result produced by the coprocessing unit, an arrangement for specifying to the first processing unit any exception in a result produced by the coprocessing unit, an arrangement for using the first processing unit to implement any function which causes an exception in a result produced by the co-processing unit, an arrangement for storing the identification of the instruction being handled by the first processing unit when a function causing any exception in a result produced by the co-processing unit occurs, and an arrangement for determing the instruction which produced the exception.
