Embodiment
[0093] The SoC compatible with the SPARC V8 structure processor is adopted, and the SoC uses the non-handshaking high-speed JTAG debugging link design structure compatible with the AHB protocol in the present invention, and effectively completes the read-write access of on-chip resources and the infusion of programs. Compared with traditional debugging methods, this debugging structure has higher speed and better stability, and reuses the standard DFT JTAG interface, saving chip pin resources. The invention has high practical value and versatility because it constructs a standard JTAG interface and an on-chip AMBA bus conversion channel.
[0094] Tests have shown that under 180nm process conditions, the traditional RS232 debugging link needs to occupy two additional signal pins, its frequency is 100MHz, its area is 0.372um2, and its maximum communication baud rate is 115200bps; while the compatible AHB in the present invention The non-handshaking high-speed JTAG debugging link...
