The eSi-3264 stands as the pinnacle of the eSi-RISC family, offering a 32/64-bit processor with advanced DSP extensions supporting SIMD (Single Instruction Multiple Data) operations. Engineered for applications requiring significant DSP functionality without a high silicon footprint, the eSi-3264 integrates dual/quad-multiply-accumulate units for complex arithmetic operations. Enhancements include both single and double precision floating-point instructions conforming to the IEEE-754 standard. With a configurable memory management unit (MMU) and cache architecture, it manages high data throughput with minimal delay. Tailored for audio, sensor hub, motion control, and similar applications, this processor delivers robust performance in a power-efficient package.
