• Manufacturer Part Number: adsp-bf548
• Description: Blackfin Embedded Processor
• Manufacturer: Analog Devices, Inc.

GENERAL DESCRIPTION
The ADSP-BF54x Blackfin processors are members of the
Blackfin
Devices/Intel Micro Signal Architecture (MSA). Blackfin pro-
cessors combine a dual-MAC state-of-the-art signal processing
engine, the advantages of a clean, orthogonal RISC-like micro-
processor instruction set, and single-instruction, multiple-data
(SIMD) multimedia capabilities into a single instruction-set
architecture.
Specific performance and memory configurations for
ADSP-BF54x Blackfin processors are shown in
