Abstract
A processing system having a CPU core and a cache transfers data between a first block of memory and a second block of memory that is preferably partitioned out of the cache as a non-cacheable scratchpad area and performs address calculations with protection and privilege checks without polluting the cache. Responsive to executing a predetermined instruction, the CPU core signals the cache to prevent caching data during transfer from system to scratchpad memory thereby reducing the number of bus turnarounds while maintaining byte granularity addressability.
