ADI 公司的ADSP-BF592是集成了ADI/Intel微信号架构(MSA)的高达400MHz Blackfin处理器,功耗低至51mW,包括了两个16位MAC信号处理引擎,两个40位ALU,四个8位视频ALU以及40位移位器,正交RISC类微处理器指令集和单指令多数据(SIMD)多媒体功能,具有先进的调试,跟踪和性能监测,主要用于工业,医疗,视频,音频和通用市场.本文介绍了ADSP-BF592主要特性,方框图, Blackfin处理器核框图以及ADSP-BF592 EZ-KIT Lite评估板主要特性,框图,电路图和材料清单. The ADSP-BF592 processor is a member 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 ADSP-BF592 processor is completely code compatible with other Blackfin processors. The ADSP-BF592 processor offers performance up to 400 MHz and reduced static power consumption. ADSP-BF592主要特性: Up to 400MHz high performance Blackfin processor Two 16-bit MACs, two 40-bit ALUs, four 8-bit video ALUs, 40-bit shifter RISC-like register and instruction model for ease of programming and compiler-friendly support Advanced debug, trace, and performance monitoring Accepts a wide range of supply voltages for internal and I/O operations, Off-chip voltage regulator interface 64-lead (9 mm × 9 mm) LFCSP package MEMORY 68K bytes of core-accessible memory 64K byte L1 instruction ROM Flexible booting options from internal L1 ROM and SPI memory or from host devices including SPI, PPI, and UART Memory management unit providing memory protection PERIPHERALS Four 32-bit timers/counters, three with PWM support 2 dual-channel, full-duplex synchronous serial ports (SPORT), supporting eight stereo I2S channels 2 serial peripheral interface (SPI) compatible ports 1 UART with IrDA support Parallel peripheral interface (PPI), supporting ITU-R 656 video data formats 2-wire interface (TWI) controller 9 peripheral DMAs 2 memory-to-memory DMA channels Event handler with 28 interrupt inputs 32 general-purpose I/Os (GPIOs), with programmable hysteresis Debug/JTAG interface On-chip PLL capable of frequency multiplication 图1.ADSP-BF592方框图 图2.ADSP-BF592 Blackfin处理器核框图 ADSP-BF592 EZ-KIT Lite评估板 The ADSP-BF592 EZ-KIT Lite® provides developers with a cost-effective method for initial evaluation of the ADSP-BF592 processor via a USB-based, PC-hosted tool set. With this EZ-KIT Lite, users can learn more about the Analog Devices (ADI) ADSP-BF592 hardware and software development, and quickly prototype a wide range of applications. The EZ-KIT Lite includes an ADSP-BF592 Blackfin Processor desktop evaluation board along with an evaluation suite of the VisualDSP++® development and debugging environment, including the C/C++ compiler, assembler, and linker. The evaluation suite of VisualDSP++ is designed to be used with the EZ-KIT Lite only. The EZ-KIT Lite also comes with a standalone debug agent board that is removable to allow a user to plug-in an external emulator.
