THE SANDBLASTER SBX 2.0 ARCHITECTURE

Sandbridge Technologies has developed a new architecture that supports wireless data rates necessary for 3.5G and 4G systems. Building upon the Sandblaster 1.0 architecture, the fully object code compatible Sandblaster SBX 2.0 architecture extends support for high bit-rate processing, MIMO-OFDM acceleration, wider vector execution, and code compression. Architectural performance improvements range from 4x to more than 10x for a variety of signal processing applications while providing 100% object code compatibility with the Sandblaster 1.0 architecture. In this paper we describe the base Sandblaster 1.0 architecture and introduce the Sandblaster 2.0 enhancements.
