ADI公司的ADSP-BF518F EZ-Board评估系统是用来评估ADSP-BF518F Blackfin处理器的功能,处理器的I/O电压为3.3V,核电压由 DP1715和AD5258来控制,而Blackfin 处理器ADSPBF518F,采用ADI/Intel微信号架构(MSA),集成了双MAC信号处理引擎,具有正交RISC类微处理器指令集,单指令多数据(SIMD)多媒体功能,主要用在工业控制,马达控制,仪器仪表,Femto基站,网络音频,VoIP等领域.本文介绍了ADSP-BF518主要特性,方框图,Blackfin 处理器核框图,以及ADSP-BF518F EZ-Board评估板主要特性,方框图,电路图和材料清单.

The ADSP-BF512/ADSP-BF512F, ADSP-BF514/ADSPBF514F, ADSP-BF516/ADSP-BF516F, ADSP-BF518/ADSPBF518F 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.

The processors are completely code compatible with other Blackfin processors.

ADSP-BF518F EZ-Board评估系统

ADSP-BF518F EZ-BoardTM Evaluation System

This EZ-Board is designed to demonstrate the ADSP-BF518F Blackfin processor capabilities. The processor has an I/O voltage of 3.3V. The core voltage of the processor is controlled by an Analog Devices ADP1715 low dropout regulator (LDO) and an Analog Devices AD5258 digipot, which is configurable over the 2-wire interface (TWI) signals.

The ADSP-BF518F EZ-Board provides example programs to demonstrate the capabilities of the product.
