Analog Devices has unveiled the newest additions to its SHARC portfolio of 32-bit floating point digital signal processors—the SHARC 2148x and SHARC 2147x series. Delivering a balance of performance and price with up to 5 Mbyte of integrated memory, high-performance SHARC 2148x and low-power SHARC 2147x series processors extend single-chip, floating point signal processing precision to a wide range of applications. With SHARC 2148x and SHARC 2147x processors, designers can take advantage of end-to-end SHARC family code compatibility and a robust suite of ADI development tools.  

SHARC 2148x series processors deliver up to 33% greater performance (400 MHz) and up to 250% more on-chip memory (5 Mbyte) than competing 32-bit floating point DSPs, distinguishing the SHARC 2148x series as the processors of choice for high definition (HD) audio and home theater applications, as well as advanced industrial applications requiring single-chip, floating point precision at a low price point.  

For portable devices and applications that require floating point processing precision with low power consumption and high environmental tolerance, new 12x12 mm SHARC 2147x series processors consume only 363 mW power (typical use-case)—up to 20% less power than competing processors—and deliver performance up to 266 MHz with up to 5 Mbyte on-chip memory to provide more performance and memory integration per square millimeter than any other competing floating point DSP.

The new SHARC 2148x and SHARC 2147x 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 optimized via Variable Instruction Set Architecture (VISA) support, which can free up as much as 30% of memory space for application code through reductions in instruction opcode sizing.
