ABSTRACT:
A data processing system including a data cache with the capability to selectively zero the contents of the data cache. The invention includes a multiplexor arranged to provide a parallel data output that is greater than the parallel data input from either a central processing unit or from a memory that are each connected to access the data cache. This multiplexor is selectively controlled to provide a parallel data output of zeroes upon the decoding of a specific zeroing instruction.
