Stream Processors Inc. announced the first members of its Storm-1 family of data-parallel DSPsthe SP16-G160 and the SP8-G80.

Based on the company's SPI Stream Processor Architecture, the Storm-1 family combines the ability to scale to 80 giga multiplications and accumulations per second (GMACs/s) performance with a C programming model. The chips are housed in a 31-by-31mm plastic ball grid array (PBGA) packaging and implemented in 130nm, 1V standard CMOS process.

The Storm-1 family is suitable for a wide range of demanding signal processing applications, such as high-definition video, H.264 HD encoding, transcoding, analytics, image processing and video surveillance with processing headroom for customer-specific enhancements.

The Storm-1 SP16-G160 device is a DSP that offers 160 giga operations per second (GOPS) and 80GMACs/s of performance by featuring a high-performance data-parallel unit (DPU) with 16 parallel lanes with five ALUs each. Each ALU contains a MAC unit and is capable of four 8-, two 16- or one 32bit operation per cycle. Input and output data for each lane is stored in on-chip lane register files that are allocated by the compiler to maximize data bandwidth.

Each device includes a MIPS32 4KEc CPU core for system tasks, and a second MIPS32 4KEc that is dedicated to handling main DSP threads and making kernel function calls to the DPU for acceleration. A rich set of I/O includes GbE, PCI and high-speed data ports for video and communications.

Pricing is $99 for the SP16-G160 and $59 for the SP8-G80 in 10,000-unit quantities. Sampling with full production expected in Q2 2007.
