Sanyo adopts new route to DSP design

Sanyo Electric has purchased Lisatek Processor Designer and Processor Generator software, as well as consulting services from CoWare.

CoWare has worked with Sanyo to develop a Lisa 2.0 model of its Sanyo digital signal processor (DSP) core.

The three-year purchase agreement will enable Sanyo to replace its current manual design methods with a Lisatek-based methodology to reduce its DSP core design cycle time by 50-66%.

"DSPs are not only the domain of a few large vendors", said Will Strauss, President of Forward Concepts.

"Many more custom DSPs from many other vendors are hidden inside consumer chips today".

"This trend is growing as languages like Lisa 2.0 and software development tools start to ease custom DSP design".

"Clearly, this is another growth opportunity for the DSP chip market".

"Customers adopting Lisatek achieve drastic improvements in productivity for their custom processor design", said Johannes Stahl, Director of Marketing at CoWare.

"Lisatek's superior performance in generating the C-compiler and RTL code is key for successful application with consumer designs".

According to Hideki Ohashi, Manager, DSP Development Section, IP Development Department, System Solution Central Business Unit, Sanyo Electric: "We evaluated a number of products, but Lisatek was an easy choice".

"The range of capabilities that Lisatek provides was far superior, and the result was a dramatic decrease in our development time".

Lisatek, based on the easy-to-understand Lisa 2.0 language, automatically generates the software development environment (assembler, debugger, and linker) from the Lisa 2.0 model.

This capability alone enabled Sanyo to cut its development time to one-third the time it previously required.

And because Lisatek generates RTL code directly, Sanyo can use that code for implementing its next generation DSP.

Sanyo already uses CoWare's ConvergenSC system-level design tools, so the company will be able to establish an integrated ESL design environment using the fast Lisatek-generated ISS model.

Through these capabilities, Sanyo expects to further reduce its design cycle time.
