ADI公司的ADSP-BF516/ADSP-BF516F和ADSP-BF518/ADSP-BF518F Blackfin处理器集成了双MAC信号处理引擎,正交RISC类微处理器指令集以及单程指令多数据(SIMD). Blackfin处理器的频率高达400MHz,具有两个16位MAC,两个40位ALU,4个8位视频ALU以及40位移位寄存器,主要用在VoIP,工业控制,马达控制,微微蜂窝,网络音频和测试仪表.本京电港论坛文章先容了BF518F主要特点, Blackfin处理器核方框架图以及ADSP-BF518F EZ评估板主要特点,电路原理图纸和质料清单(BOM). ADSP-BF516/ADSP-BF516F, ADSP-BF518/ADSP-BF518F 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, multipledata (SIMD) multimedia capabilities into a single instruction-set architecture. The processors are completely code compatible with other Blackfin processors. By integrating a rich set of industry-leading system peripherals and memory, Blackfin processors are the platform of choice for next-generation applications that require RISC-like programmability, multimedia support, and leading-edge signal processing in one integrated package. PORTABLE LOW POWER ARCHITECTURE Blackfin processors provide world-class power management and performance. They are produced with a low power and low voltage design methodology and feature on-chip dynamic power management, which is the ability to vary both the voltage and frequency of operation to significantly lower overall power consumption. This capability can result in a substantial reduction in power consumption, compared with just varying the frequency of operation. This allows longer battery life for portable appliances. SYSTEM INTEGRATION The ADSP-BF51x processors are highly integrated system-on-a-chip solutions for the next generation of embedded network connected applications. By combining industry-standard interfaces with a high performance signal processing core, costeffective applications can be developed quickly, without the need for costly external components. The system peripherals include an IEEE-compliant 802.3 10/100 Ethernet MAC with IEEE-1588 support (ADSP-BF518/ADSP-BF518F only), an RSI controller, a TWI controller, two UART ports, two SPI ports, two serial ports (SPORTs), nine general-purpose 32-bit timers (eight with PWM capability), three-phase PWM for motor control, a real-time clock, a watchdog timer, and a parallel peripheral interface (PPI). PROCESSOR PERIPHERALS The ADSP-BF51x processors contain a rich set of peripherals connected to the core via several high bandwidth buses, providing flexibility in system configuration as well as excellent overall system performance (see Figure 1 on Page 4). The processors contain dedicated network communication modules and high speed serial and parallel ports, an interrupt controller for flexible management of interrupts from the on-chip peripherals or external sources, and power management control functions to tailor the performance and power characteristics of the processor and system to many application scenarios. All of the peripherals, except for the general-purpose I/O, rotary counter, TWI, three-phase PWM, real-time clock, and timers, are supported by a flexible DMA structure. There are also separate memory DMA channels dedicated to data transfers between the processor’s various memory spaces, including external SDRAM and asynchronous memory. Multiple on-chip buses provide enough bandwidth to keep the processor core running along with activity on all of the on-chip and external peripherals.

The board is not intended for use as a consumer end product or as a portion of a consumer end product. The board is an open system design which does not include a shielded enclosure and therefore may cause interference to other electrical devices in close proximity. This board should not be used in or near any medical equipment or RF devices.
