摘要
Abstract
To implement the on-chip-debugger ( OCD) suitable to multiple 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.关键词
