LSI Logic first for Carmel
Steve Bush System-on-a-chip company LSI Logic is the first licensee of Siemens’ recently introduced Carmel DSP core. “There was a gap at the top of the our portfolio,” said LSI spokesman Mike Casey. “We needed a DSP core with performance over 100Mips.” Carmel is an open architecture DSP rated at 1.8 billion operation/s. “A number of our customers have been pushing us to go the open DSP route,” said Casey. His argument is that companies needing system chips are attracted to an architecture that can be bought from more than one company, and cites the ARM Risc as an example of a core that is popular because it can be bought from multiple vendors: “Part of the deal with Siemens is that we actively encouraging others to take up the core.” Carmel will now sit above the DSP Group’s Oak processor in LSI’s range. “Oak will handle our lower end and mainstream applications and we will continue to invest in it,” said Casey. “It will probably top-out at around 100Mips.” But will the Siemens processor be overkill for many applications just out of reach of Oak? “No,” says Casey, “running it at reduced clock speeds and voltages brings its power consumption down with its performance. It is well suited to today’s handsets.” Carmel is aimed at wireless communication systems, high speed xDSL modems and multimedia applications.
