Softcore for ADSP-2181/2191

Started by SpiffyGuy October 15, 2009
Hello,

Does anyone know of a softcore for either the Analog Devices ADSP-2191
or 2181 DSPs? Looks like the 2191's life is only 2 years and I need
something that is code compatible with the 2181 DSP.

Thanks!

I haven't heard that the 2191 is EOL, but it seems to me that it would be easier to port code to another DSP that try to duplicate it with a softcore. From strictly a MIPs and peripheral point of view, most of the Blackfin product line can serve the same purpose. From an assembly language perspective, I think it would be easier to port 218x or 219x code to the SHARC. The ADSP-21371 would be one possibility. It has all the peripherals of the 2191 and is much more powerful. It even costs less. I learned 218x and 219x code before I learned SHARC assembly. It was a very easy transition.

I have never heard of such cores and i'm afraid they do not exist.

Who told you that? According to my sources 2191 will be in production for the next 5 years. Anyway, being you i would migrate to either Blackfin or SHARC. -- Alexander

Thanks for the info Al. Our components group at work passed the info on to me and they always want parts that are available for around 8 years. I will double check with Analog Devices to make sure. Unfortunately, we have no budget to port the code so I'm trying to find an easy transition. Our legacy code is from the 2181 so we are now using the 2191 for that reason. A couple other projects that have had similar code migration budget issues have bought softcores (TI DSPs for example) that are cycle accurate, so figured I'd see if anyone knew of one. Appreciate the help! I will look into the Blackfin and SHARC DSPs.

Then they better buy eight years worth of parts... S.
