Abstract

This paper investigates various approaches to embed the functionality of in-circuit emulation (ICE) into microprocessor cores in SoC (System-On-Chip) chips. Three styles of ICE's (hardware-oriented, software-oriented and hybrid) are defined and implemented. They are integrated with a synthesizable ARM7 microprocessor core and synthesized to gate level to quantitatively analyze and compare their performance, cost and debugging features.
