In an implementation, a processing system includes an instruction fetch (IF) memory storing IF instructions; an arithmetic/logic (AL) instruction memory (IMemory) storing AL instructions; and a programmable instruction fetch mechanism to generate IMemory instruction addresses, from IF instructions fetched from the IF memory, to select AL instructions to be fetched from the IMemory for execution, wherein at least one IF instruction includes a loop count field indicating a number of iterations of a loop to be performed, a loop start address of the loop, and a loop end address of the loop. |
