Analog Devices Inc. ADSP-2183x/-SC83x High-Performance SHARC®-FX DSPs
Analog Devices ADSP-2183x/-SC83x High-Performance SHARC®-FX Digital Signal Processors (DSPs) are members of the SHARC-FX family of products. The SHARC-FX core utilizes a single-instruction, multiple-data (SIMD) vector floating-point architecture and can issue up to four instructions per cycle in most combinations. The SHARCFX core inside the ADSP-2183x/ADSP-SC83x processors offers processing speeds of up to 1GHz coupled with up to 2MB of L2 memory for low-latency applications. For applications seeking enhanced connectivity options such as Ethernet, the ADSPSC834/SC835 includes an Arm® Cortex®-M33 in addition to the SHARC-FX core. All members of the SHARC-FX family have onboard IIR and FIR accelerators as well as an efficient auto-vectorizing compiler for C/C++ programming.
The SHARC-FX core supports scalar and vector operations on all data types in vectors up to 256-bits, including integer, fixed point, floating-point, complex 16-bit/32-bit fixed-point, and complex 32-bit/64-bit floating-point. Eight Float32 multiply/accumulate operations are allowed per cycle, with no constraints on alignment. The SHARC-FX core also features large register sets (32 data registers), reducing the need for stack save and restore. The peripherals and system architecture of the ADI ADSP-2183x/ADSP-SC83x processors are compatible with previous SHARC processors, allowing for easy application porting.
By integrating a set of industry-leading system peripherals and memory, this ADI family of processors is the platform of choice for applications that require leading-edge signal processing in one integrated package. These applications include automotive, professional audio, and industrial-based applications that require high floating-point performance.
