The SP-3 is a fully synthesizable DSP Core based on the high performance, low power, SIMD (Single Instruction Multiple Data) architecture. The SP-3 provides an optimized balance between performance, power, cost and ease of programming.

The SP-3, available with 24x16 or 32x32-bit multiplier configurations, delivers the needed performance for DSP oriented applications such as:

VoP (Voice-over-Packet) G.7XX Vocoders G.168 - 2000 Echo Canceller DTMF VAD/CNG Imaging JPEG
