Abstract
Methods and apparatus are provided for performing loop execution. Modifier registers are used to hold loop counter values. Modifier register information and program memory address information are included in the loop instruction. When a processor executes a loop instruction, it decodes the instruction, identifies the modifier register, and accesses the register value to determine if the processor will jump back based on the memory address information. The loop execution can incur no clock cycle penalties.
