What is the difference between real-time event debug and advance event trigger (AET)?
On a real-time system, the real time event must be processed (such as the hardware interrupt and the hardware timer). In the usual event debug mode, a software breakpoint is inserted at the interrupt program entry point. Once the event is triggered, the program will be stopped at breakpoint, then we can view the information we want. But once the target DSP is stopped, we will lose other real-time events and real-time streams. The advance event trigger (AET) solves this problem. Using AET, we can catch the real-time event without stopping the DSP. To Run AET, we must use a 560 emulator and select a DSP chip with EJTAG(621x,64x, 671x, 55x,OMAP). 510 emulators do not support AET. Summary. 560 emulators: support high speed RTDX, AET (must work with DSP chip with EJTAG). 560 emulators are called “real-time emulator”. 510 emulators: support low speed RTDX but do not support AET. 510 emulators are called “semi-real-time emulator” or “non real-time emulator”. Note: 560 includes 510’s main func
