Latency of posting and servicing the software interrupt.

Karthik Rao1

Hi,

Here is the software versions of the tools I'm using,

    CCS : Version: 5.3.0.00090
    XDC tools : 3.24.5.48
    Compiler version TI 6.1.0
    SYS/BIOS : 6.34.2.18
    Device :TMS320F28335

I'm posting a software interrupt in the ADC isr(HWI),just before acknowleding the ADC interrupt.

My question is what is the minimum time required to service the posted software interrupt?

Say,I have only one HWI(i.e., ADC isr) and only one SWI. I'm setting a GPIO just before posting the SWI and making it low after entering SWI. What would be the minimum time that the GPIO remains high? What are the parameters that would cause the delay?

 

Thanks,

Karthik.
