Reverse Engineering the ARM1 Processor’s Microinstructions

Wed, 21 Jun 2017 02:23:00 +0000


This article looks at how the ARM1 processor executes instructions. Unexpectedly, the ARM1 uses microcode, executing multiple microinstructions for each instruction. This microcode is stored in the instruction decode PLA, shown below. RISC processors generally don’t use microcode, so I was surprised to find microcode at the heart of the ARM1. Unlike most microcoded processors, […](image)
