I'm using F28335 and I'm going to use dsp/bios on my project. I have some questions about dsp/bios:
1. After reading document SPRAXX9, I'm confusing about the way that bios handle hardware interrupt when processing an interrupt in a SWI and TSK. HWI dispathcer epilogue is called after SWI scheduler (and user define swi function) in SWI and after SEM pend in TSK. It do a very long time to handle a HWI. Is that real that dsp bios handle the HWI like these way when processing a interrupt in SWI or TSK??
2. when using C28+FPU processer, would FPU's register be saved by bios when doing a context save?
3.when i use HWI_enter in asm file, CCS would suggest that "[E0002] Invalid mnemonic specification". why? How to use that
tks
