A loop buffer for storing and holding instructions executed within loops for digital signal processing. Control logic detects the beginning and ending of a loop to signal the loop buffer control logic to start instruction execution in a cyclical fashion using the instructions stored within the loop buffer. After completion of the required number of loops, the instructions in the loop buffer are overwritten with new instructions until the next loop is to be processed. The loop buffer conserves power by avoiding the fetching of instructions unnecessarily from memory. |
