Abstract
A data processing systemincludes an instruction cachehaving an associated buffer memory. The buffer memorycan operate in a buffer mode or in a microcache mode. The buffer memory is switched into the microcache mode upon program loop detection performed by loop detector circuitry. When operating in the microcache mode, instruction data is read from the buffer memorywithout requiring an access to the instruction cache
