The ADSP-2183x/ADSP-SC83x digital signal processors (DSPs) are members of the SHARC^®-FX family of products. The SHARC-FX core uses a single-instruction, multiple-data (SIMD) vector floating-point architecture and can issue up to four instructions per cycle in most combinations. The SHARC-FX core inside the ADSP-2183x/ADSP-SC83x processors offers processing speeds of up to 1 GHz coupled with up to 2 MB of L2 memory for low latency applications. For applications seeking enhanced connectivity options such as Ethernet, the ADSP-SC834/SC835 includes an Arm^® Cortex^®-M33 in addition to the SHARC-FX core. All members of the SHARC-FX family have on-board 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), thus reducing the need for stack save and restore. The peripherals and system architecture of the 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 family of processors is the platform of choice for applications that require leading-edge signal processing in one integrated package. These applications span a wide array of markets, including automotive, professional audio, and industrial-based applications that require high floating-point performance.
