ADSP-BF561: Blackfin Symmetric Multi-Processor for Consumer Multimedia
The ADSP-BF561 processor is a high performance member of the Blackfin® family of products targeting a variety of multimedia, industrial, and telecommunications applications. At the heart of this device are two independent Analog Devices Blackfin processors. These Blackfin processors combine a dual-MAC state-of-the-art signal processing engine, the advantage of a clean, orthogonal RISC-like microprocessor instruction set, and single instruction, multiple data (SIMD) multimedia capabilities in a single instruction set architecture.

The ADSP-BF561 processor has 328K bytes of on-chip memory.
Each Blackfin core includes:
16K bytes of instruction SRAM/cache
16K bytes of instruction SRAM
32K bytes of data SRAM/cache
32K bytes of data SRAM
4K bytes of scratchpad SRAM
Additional on-chip memory peripherals include:
128K bytes of low latency on-chip L2 SRAM
Four-channel internal memory DMA controller
External memory controller with glueless support for SDRAM, mobile SDRAM, SRAM, and flash.
