About DSP Programming

Digital Signal Processing is present, for many of us, in devices we use in everyday life: mobile telephones, cordless telephones, car radios, headsets, etc. use this technique. Bithium leverages the accumulated know-how in this area and provides DSP programming and development services.

Audio processing is presently, at Bithium, the main area of adoption of Digital Signal Processing.

Here are some Questions and Answers on this topic:

What is a DSP? How different is it from a microprocessor?

The DSP acronym is also used to designate a specially designed microprocessor with specific architecture and instruction set optimized for Digital Signal Processing purposes. Although a general microprocessor can run Digital Signal Processing algorithms, it typically has a higher power consumption, and price, than a specific DSP with lower latency and lower power consumption due to its internal architecture.

Although specifically designed for running Digital Signal Processing algorithms, a DSP can also run non-time critical routines, behaving also as an applications processor.

Why would my application require a DSP?

If your application requires digital audio or video in real-time and some processing is required to achieve optimum results, a DSP will most probably be of good use in the design of your product.

Will the use of a DSP make the end product too expensive?

Most probably not, as the DSP may, in some cases, also replace a general applications processor. The preferred option may also be to use a specific SoC with integrated DSP that should constitute an economical solution for mass market adoption.

Why should I consider Bithium as a partner for my project involving DSPs?

Because of Bithium's experience in bringing reliable, proven DSP based products to the market and our engagement in getting things done.

We will work on the required DSP algorithms with our reliable partners to offer you a complete no-hassle solution.

What DSP has Bithium worked with?

We have been working with the below platforms:

• • Texas Instruments TMS320C55xx

  • Texas Instruments TMS320C64xx

  • Dialog Semiconductor Gen2DSP

We are however open to work with a different platform should that be required. You are also most welcome to discuss with us your requirements.
