Re: Market for General Purpose DSPs
I agree you Vishal, but considering multiple arithmetic units may require memory architectures to support several accesses per instruction cycle which may cal DSP with high cost..

Re: Market for General Purpose DSPs
That is my point samicksha. The DSP are advancing and offering lot of advanced functionlities integrated in the single chip. So, in case of high end applicaiton they are capable of execute the complex task easily and in case of relatively less computational hungry application, you can always go back to the non floating point DSPs and take an advantage of lesser cost and higher speed of execution.

Re: Market for General Purpose DSPs
May Be Vishal, but in case of  DSP most of them use fixed arithmetic, because in real world signal processing the additional range provided by floating point is not needed, and there is a large speed benefit and cost benefit due to reduced hardware complexity...

Market for General Purpose DSPs
I think, there is still enough market for the general puspose DSP chips. May it be low or middle volume market. This is similar to microcontrollers which are now more versatile then before. Which can be accepted by almost all type of market. Similarly by providing higher integration in to general purpose DSPs will keep the market for them alive compared to Single function chips.

 

Take an example of Motor Control. A general purpose DSP will be able to implement different algorithms depending upon types of motors and types of application. While single purpose chip will not be able to achieve that.

 

Although, fixed purpose chips will definitely save time to market but at the trade for cost or size probably.

If your interest is less in applications of analog technology than other problems, and you want to find out whatís happening in real analog, here's where you should be.
When it comes to this monthís ISSCC show, there are plenty of sections dedicated to solving issues with integrated analog technology. Here, our blogger looks at the sessions that offer new insight to difficult problems.
The International Solid State Circuits Conference kicks off February 9. While the mass media will focus on the biggest memory, faster processor, and smallest geometries reported, I prefer to look at the analog stuff.
Once semiconductor companies master the fabrication of micro-electromechanical systems (which they have), the next step is to master nano-electromechanical systems (which they are starting to).
