Reusable embedded in-circuit emulator

In this paper, we introduce the Reusable Embedded In-Circuit Emulator (EICE) and Reusable EICE development system. The main functions of the EICE we designed are testing and debugging. The architecture of EICE is reusable and based on the IEEE 1149.1 boundary scan architecture. The EICE development system can help EICE to reduce the development time for a microcontroller/microprocessor. We implemented EICE in ASIC and FPGA formats and the development system had been demonstrated in two microcontroller.
