3 / 68 page ADSP-BF542/4/8/9 Preliminary Technical Data Rev. PrE | Page 3 of 68 | April 2007 GENERAL DESCRIPTION The ADSP-BF542/4/8/9 processors are members of the Blackfin family of products, incorporating the Analog Devices/Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. Specific performance and memory configurations for ADSP-BF542/4/8/9 processors are shown in Table 1. Specific peripherals for ADSP-BF542/4/8/9 processors are shown in Table 2. Table 1.
