摘　　要：为了实现适用于多种架构的嵌入式处理器的在线调试器,提出分层设计的思想,利用部分硬件驱动化的方法,设计实现了一款基于CK-CPU的多架构嵌入式处理器在线调试器。该调试器能适用于内含不同调试接口电路HAD的嵌入式处理器。在需要适用于另一架构的嵌入式处理器时,硬件资源仅增加6.09K。由于采用了硬件驱动化的方法,有利于调试器的升级换代,该款在线调试器平均下载速度能到1367KB/S。To implement the on-chip-debugger （OCD） suitable to muhiple architecture embedded processors, in this paper we propose a hierarchical design idea, and by the way of software driving and acting part of the hardware, we design and implement a CK-CPU-based OCD for multiple architecture embedded processors. The OCD can fit the embedded processor with different debugging interface circuits HAD. It only takes extra 6.09K logic gate while in need of adapting for an embedded processor in different architecture. Since some of the hardware is acted by software driving, it is beneficial to the update and Upgrade of the OCD. The average download speed of this OCD can reach 1367KB/s.
