摘要
A data processing device having a central processing unit for fetching instructions from a program memory, decoding the instructions and sending a signal to a coprocessor if a coprocessor-type instruction is decoded; a coprocessor for decoding the coprocessor-type instructions upon receipt of the signal; and a loop buffer for receiving from the program memory instructions within a loop and storing the instructions within the loop when the coprocessor decodes a loop operation from the coprocessor-type instructions, wherein the instructions within the loop are retrieved from the loop buffer for execution in a subsequent iteration of the loop, and wherein a disable signal is sent to the program memory for inhibiting access of the program memory while the instructions within the loop are retrieved from the loop buffer.
