DSPBIOS and SysBIOS on C66

C. García
Intellectual 830 points
Other Parts Discussed in Thread: SYSBIOS

Hi,

 

I worked with CCS 3 and so with the DSPBIOS with the DM642 processor and now with the C66 core I have some dubs:

1- What is the difference between DSPBIOS and SysBIOS?

2.-Is possible to use DSPBIOS with c66?

3.-Why to use SysBIOS with C66 and not  DSPBIOS?

4- If is possible to use DSPBIOS with the C66, Could somebody tell me, please, how the SysBIOS affects the performance vs DSPBIOS in the same C66?

Thanks in advance.

    Shmulik,

    Hopefully, these answers help.

    1.  From a strictly C6000 user's perspective, SYS/BIOS is the same as saying DSP Bios 6.0.  The reason for the name change comes from the fact that DSP/Bios 5.x and earlier were only supported on TI DSP Platforms (C6000, C5000).  The SYS/BIOS name reflects the fact that this version of Bios is also supported on Microcontroller architectures (essentially BIOS for whole SYStems, not just for the DSP).  But coming from the DM648 platform, you likely don't care about any platforms other than the C6000, so to you, it's just the next generation of BIOS.

    2-4.  DSP/Bios 5.x is not supported on the C66x Platforms.  All new development and features is on the SYS/Bios generation.  No new architectures will be supported on the 5.x generation.  I, personally haven't ported any applications from DSP/Bios 5.x to SYS/Bios, but there is an application note here: http://www.ti.com/lit/pdf/spraas7 that discusses the process.
