The ADSP-2184x/SC84x digital signal processors (DSPs) are members of the SHARC® family of products, featuring the next-generation SHARC-FX DSP core offering processing speeds of up to 1.2 GHz coupled with up to 4 MB of L2 memory for low-latency applications. For applications requiring enhanced connectivity options such as Ethernet and USB, the ADSP-SC84x includes both a SHARC-FX DSP core and dual Arm® Cortex®-A55 cores. All members of the ADSP-SC84x/2184x family feature on-chip 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. The processor allows eight float32 multiply/accumulate operations per cycle with no constraints on alignment. The processor comes with large register sets (32 data registers), thus reducing the need for stack save and restore. The peripherals and system architecture of the ADSP-2184x/ADSP-SC84x processors are compatible with previous SHARC processors, allowing for easy application porting.
By integrating a rich 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.
APPLICATIONS
- Automotive:
- audio for head units and amplifiers, ANC/RNC, Personal Sound Zones, digital cockpit, ICC, AEC/Mic beamforming, ADAS
- Consumer:
- speakers, sound bars, AVRs, conferencing systems, mixing consoles, microphone arrays
