Highest code density, Low Power 32-bit Processor with optional DSP

The Beyond BA22 32-bit processor offers the highest code density of any processor in its class, reducing die size and memory requirements. In addition, the BA22 was designed to minimize code size, gate and flip-flop count while obtaining performance exceeding ARM9. The processor is extremely configurable, allowing for variety of size/performance trade-offs, and is proven in volume production silicon.
