Design of Halt-Mode and Monitoring-Mode On-Chip Debugger 2G for Core-A

Xuelong Xu, Jingzhe Xu, Donghoon Lee, Daekeon Park, and Jusung Park

Abstract—Nowadays, the SoC is concentrated by all over the world with interest. The design trend of the SoC is hardware and software co-design which includes the design of hardware structure in RTL level and the development of embedded software. As the complexity of SoC design increases with technology development, the observability of the SoC’s internal state is no longer easy to achieve. Because of the above reasons, debugging the SoC system becomes very difficult and time-consuming. So we need a reliable debugger to find the bugs in the SoC and embedded software. In this paper, we deal with implementation of a hardware debugger named OCD2G which is based on IEEE 1149.1 JTAG standard and supports halt-mode and monitoring-mode debugging. In order to verify the operation of OCD2G, the designed debugger is integrated into the 32bit RISC processor - Core-A (Core-A is an embedded processor designed in South Korea) and is tested by interconnecting with software debugger.

Index Terms—Debugger, JTAG, On-Chip Debugger, Processor.
