Analog Devices has unveiled additions to its SHARC portfolio of 32bit floating- point DSPs, the high-performance SHARC 2148x and low-power SHARC 2147x series. The processors extend single-chip, floating-point signal processing precision to a range of applications and enable high-end system functionality in portable devices. The 2148x series processors deliver performance up to 400MHz and features 5Mbit on-chip memory. The processors are suitable for high- definition audio and home theatre applications. For portable devices and applications like advanced driver assistance systems, new 12x12mm 2147x series processors consume 363mW power and deliver performance up to 266MHz with up to 5Mbit on-chip memory. The processors feature dedicated hardware accelerators with independent compute units and DMA memory mapping, enabling the ability to execute FFT/FIR/IIR signal processing operations in the background to free up MIPS for core processing. Memory usage is optimised via variable instruction set architecture support, which can free up memory space for application code through reductions in instruction opcode sizing.
