Couth IT

We provide DSP software solutions for multimedia applications.

The Embedded Software Group specializes in developing highly optimized software solutions with very low program and data memory footprint and very high speed of execution (lowest MIPS) while being power efficient. This is essential in applications such as cell phones, PDAs and other battery operated hand-held devices as well as in high density applications (such as VOIP gateways) wherein the bill of materials can be considerably reduced.

We license highly optimized, best-in-class, speech, audio, and video codecs to OEMs/ Design Houses. We also provide services in the design and development of digital signal processing software solutions for multimedia applications. All our solutions are targeted to provide the best performance in terms of lowest MIPS and memory footprint in the industry. We provide excellent support to customers to integrate and “internalize” the delivered solutions.

Several of our solutions have been deployed in high-volume applications such as (voice, feature or smart) cell phones, (personal) media players, PDAs and other gateway applications.

Components

Our portfolio includes, as shown below, many highly optimized software components on the Texas Instruments™ (e.g., TI C55x, TI C64x) and ARM® (e.g., ARM9, ARM9E, ARM11) DSPs.
