picoChip has boosted its stature further in massively multicore architectures with the announcement of new high-performance picoArray devices. The PC202-10, PC203-10 and PC205-10 multicore DSPs deliver processing power of up to 262GIPS and 35GMACS. These enhanced members of the PC20x series allow designers to deliver advanced features and use fewer devices in highly demanding applications such as advanced wireless infrastructure products, claims picoChip.

The PC20xx-10 devices are based on the same multicore picoArray architecture as existing PC20x products, but with a larger array of processors, whilst retaining full code compatibility. The performance uplift in the PC20x-10 devices is achieved not by traditional clock speed increases or by shrinking the semiconductor manufacturing technology employed: instead the multicore nature of the picoArray is used to increase the number of processor elements in the devices from 248 to 273. This strategy, says picoChip also increases memory size by 8 percent. Because clock rate does not change, the new devices are fully code-compatible; software written for the smaller chips can immediately run on the new devices.

Moreover, picoChip says that the extra processing headroom of the PC2xx-10 devices gives OEMs significantly more flexibility in creating 3G, WiMAX and 4G wireless products.

Priced from $31 in volume, all PC20x-10 devices are programmed in standard ANSI C, and feature a cryptographic engine as well as an optimized co-processor for FFT/IFFT, Viterbi and turbo decoders.
