How to Build a Board with DSP chip

Hi , I want to build a board (BSP) . I have with me a TI processor . and want to use some RTOS (like pSOS/VxWorks ). I don;t know whether this is possible but want your Inputs. If suppose I have the RTOSes I have mentioned do their kernel run on TI processor chips. Getting up a Host/Target ENV will be my next job.

TIA, Simone81

Do you want to build a BSP (a software package that supports a particular CPU card), or do you want to build a CPU card using a particular CPU?

If #1, unless you have extensive experience, buy one from the board vendor.

if #2, unless you have 2o years design experience, buy a board.

Speaking only for myself,

Joe Durusau

first, ask if they have a version of the kernel that will run on your chip. Then, if you aren't designing the board ask the board vendor if they can sell you a BSP. If they can't, or if you are designing your own board, you might think about looking for a contractor to design you a BSP. If you can't do that contract with WindRiver for BSP design classes. Developing a BSP is non-trivial, and unless you just really can't afford to have someone do it for you or you are experienced with vxworks you probably will find it cheaper to buy elsewhere (although the up-front expensive is massive, you WILL recoup it in gained development time).

Sim> Hi ,

I do not have the experience but dying to get the same .

i'll tell you my plight... I know some basics of pSOS . I have a TI DSP chip which is of no use to any one else in our lab so I could probably use it to get my Dream Embedded System Going. I can invest on the other components such as Serial Interface. PCB required if any. As I am from a non-Electronics background I want to know the components required. Googling has not fetched me any DSP/pSOS pointers .

I hope I answered your Qs so that you can help me better. Thanks for your Time.

Regards, Simone Mehta.

pSOS was sold to another real time OS firm (Wind River) several years ago. There is a newsgroup around for it, but even back then that group was pretty quiet. pSOS was/is used in Otis elevator systems.

Your best bet these days might well be application notes from various IC manufacturers. Don't neglect the PIC and assembly, which is pretty basic, and has all sorts of ANs available.

Yeah ur rgt... that group is really silent especially even after me cross-posting to that group.

thats good piece of info thanks...

Can I contact you offline about more info on these as I don't understand your tech speak.

Thanks again for your time.

Hello Simone, there IS no DSP port of pSOSystem. There have been attempts to do so, but they have not been comercially successfull.

So the reason for the quietness of the comp.os.pSOS might be due to the subject: DSP and pSOSystem.

So be convinced, the quietness is not because of your post. :-) It might be that the usage of the "killed" RTOS has been reduced in the recent years?

Hope it helped.

PS: I still use pSOSystem for ARM...

Correct its called DSP BIOS. It's free when you buy a Code Composer Studio (the next generation of the GO DSP IDE actually supported by TI) license. It's got most of the features you expect from an RTOS....dynamic thread control, semaphores, etc...and the price is tough to beat.

Although we just got a call from Wind River from somebody sniffing around to find out if we might owe them license money. Talk about gall.

Check VspWorks from WindRiver, a DSP RTOS which works great !!!

Well I am still a Big Fan of pSOS because of its simplicity when compared to WR's VxWorks and also because of its compa

It helped a lot . Thanks.

To just quickly summarise this thread, I can use a Arm board with pSOS running and a DSP can at best be a co-processor .

Thanks, Simone Mehta

If you like the API, you might find RTEMS familiar. There's an ARM V7 port and a TI C3x/C4x DSP port as well.
