Abstract
  • The AE32000 processor core, developed by Advanced Digital Chips Inc., Korea, is used primarily in the embedded processing environment. The AE32000 simulator models this embedded processor core having high code density. An enhanced simulator was developed to study the performance of the present Instruction Set Architecture after comparison with the Simplescalar ARM simulator. ARM is among the most widely used processor cores for embedded applications and so was chosen for this comparison. Code density of the AE32000 is very high because of its shorter instruction length. This results in a smaller footprint inside the memory. But the longer instruction length of the ARM proves better when it comes to performance. The LERI(Load Extension Register Immediate) unit of the AE32000 has a special role before instructions that need long immediate values during execution.
