MIPS Computation

Venkat Kumar76658

Hi Everyone,

I've a doubt on the computation of MIPS.

We have selected TI6486 DSP at 500 MHz frequency for the design.

There are some tasks to be performed in this DSP at every 10ms. 

This is a new project and we have not done any coding as of now. We are estimating the feasibility of the MIPS now.

Please help me with any points on this subject.

 

Thanks.

Regards,

Venkat R

    Since you have two posts that refer to the xxx6486, I will assume you mean the TCI6486 or TMS320TCI6486. If you have not done so, you will need to contact your TI sales office for information on support for this device. Without knowing any more about your application, it is not easy to make a recommendation.

    The front page of our DSP datasheet includes a maximum computation rate for different multiplication and accumulation operations. Each core has 8 execution units that can run up to 8 instructions in parallel in a single clock cycle. There are technology maximums for illustration purposes.

    Your application will need to do a certain set of operations in a certain amount of time. If it needs to do 2 million 16-bit MACs per second, you would be clearly able to do that. If it needs to do 2 trillion 16-bit MACs per second, then a single multi-core DSP would not be adequate, but several could be used to get there.

    We have a lot of application notes and articles on the TI Wiki Pages that would be helpful for you to learn about making a advantage of TI DSP technology. And we have several Third Party companies and Elite Design Houses who could help you with getting started and completing your task. Go to www.ti.com and click on "Developer & Design House Network" under the Support heading.

    Hi RandyP,

    Thanks a lot for your reply. I was referring to TCI6486 DSP.
