ADSPSC57xSHARC双核处理器解决方案（特性,框图,电路图）ADI公司的ADSP-SC57x/2157x系列处理器集成了两个增强型SHARC+内核和先进的DSP加速器(FIR,IIR),功耗低于2W,功效比以前的SHARC产品高5倍以上,专为需要DSP协处理器并包括两个SHARC+内核和一个匹配DSP内核的外设集的应用而设计,主要用在汽车,消费电子和专业音频,多轴电机控制和能源分配系统.本文介绍了ADSP-SC57x/ADSP-2157x系统特性,处理器框图,ARM Cortex-A5处理器器框图,SHARC处理器框图,SHARC+SIMD处理器核框图以及评估板ADSP-SC573 EZ-KIT主要特性,框图,电路图和材料清单.The ADSP-SC57x/ADSP-2157x processors are members of theSHARC family of products. The ADSP-SC57x processor isbased on the SHARC+ dual-core and the ARM Cortex-A5core. The ADSP-SC57x/ADSP-2157x SHARC processors aremembers of the single-instrucTIon, mulTIple data (SIMD)SHARC family of digital signal processors (DSPs) that featureAnalog Devices Super Harvard Architecture. These 32-bit/40-bit/64-bit floaTIng-point processors are opTImized for high performanceaudio/floating-point applications with large on-chipstatic random-access memory (SRAM), multiple internal busesthat eliminate input/output (I/O) bottlenecks, and innovativedigital audio interfaces (DAI). New additions to the SHARC+core include cache enhancements and branch prediction, whilemaintaining instruction set compatibility to previous SHARC products.By integrating a set of industry leading system peripherals andmemory, the ARM Cortex-A5 and SHARC processor is the platform of choice for applicationsthat require programmability similar to reducedinstruction set computing (RISC), multimedia support, andleading edge signal processing in one integrated package. Theseapplications span a wide array of markets, including automotive,professional audio, and industrial-based applications thatrequire high floating-point performance.ADSP-SC57x/ADSP-2157x系统特性:Dual-enhanced SHARC+ high performance floating-pointcoresUp to 450 MHz per SHARC+ coreUp to 3 Mb (384 kB) L1 SRAM memory per core with parity(optional ability to configure as cache)32-bit, 40-bit, and 64-bit floating-point support32-bit fixed pointByte, short word, word, long word addressedARM Cortex-A5 core450 MHz/720 DMIPS with NEON/VFPv4-D16/Jazelle32 kB L1 instruction cache with parity/32 kB L1 data cachewith parity256 kB L2 cache with parityPowerful DMA systemOn-chip memory protection图1.ADSP-SC57x/ADSP-2157x处理器框图图2.ADSP-SC57x/ADSP-2157xARM Cortex-A5处理器器框图图3.SHARC处理器框图图4.SHARC+SIMD处理器核框图评估板ADSP-SC573 EZ-KITThank you for purchasing the Analog Devices, Inc. ADSP-SC573 EZ-KITevaluation system.The ADSP-SC573 processor is a members of the SHARC family of products. The ADSP-SC573 processor isbased on the SHARC+ dual-core and the ARM Cortex-A5TM core. The ADSP-SC573SHARC processor is amembers of the SIMD SHARC family of DSPs that feature Analog Devices Super Harvard Architecture. These 32-bit/40- bit/64-bit floating-point processors are optimized for high performance audio/floating-point applicationswith their large onchip SRAM, multiple internal buses to eliminate I/O bottlenecks, and innovative digital audiointerfaces (DAI). New enhancements to the SHARC+ core add cache enhancements, branch prediction, and otherinstruction set improvementsall while maintaining instruction set compatibility to previous SHARC products.The EZ-KIT ships with all of the necessary hardware to get you up and running and start the evaluation immediately.The EZ-KIT contains an expansion interface 3 (EI3). This interface provides for connecting with daughter boardsto expand on the functionality of the EZ-KIT.The evaluation board is designed to be used in conjunction with the CrossCore Embedded Studio developmentenvironment for advanced application code development and debug such as: Create, compile, assemble, and link application programs written in C+, C, and assembly Load, run, step, halt, and set breakpoints in application programs Read and write data and program memory Read and write core and peripheral registers图4.评估板ADSP-SC573 EZ-KIT外形图评估板ADSP-SC573 EZ-KIT主要特性: Analog Devices ADSP-SC573 processor 400 ball BGA 25 MHz oscillator DDR3 Memory 128Mx16 bit (2Gbit ) Micron MT41J128M16JT-125 1.5V SPI Flash (SPI2) Memory 128Mbit Windbond32M-bit Serial Flash Memory with Dual and Quad SPI (W25Q32) Single/Dual/Quad SPI SPI EEPROM Microchip 4K I2C Serial EEPROM (24AA04) Ethernet Texas Instruments 10/100/1000 Ethernet Physical Layer (DP83865) Broadcom BroadR-Reach Single Port Automotive Ethernet Transceiver (BCM89810) Cirrus Logic Fractional-N Clock Multiplier (CS2100) Two RJ45 connectors Audio Analog Devices 12 Channel, High Performance, 192kHz, 24-Bit DAC (ADAU1962A) Analog Devices Quad ADC with Diagnostics (ADAU1977) Analog Devices Quad Analog-to-Digital Converter (ADAU1979) 12 RCA connectors. 12 outputs or 8 outputs/4 inputs Universal Asynchronous Receiver/Transmitter (UART3) FTDI USB to UART (FT232R) USB micro-B CAN NXP Enhanced fault-tolerant CAN transceiver (TJA1055) NXP High-speed CAN transceiver for partial networking (TJA1145) Two RJ11connectors A2B Analog Devices Automotive Audio Bus A2B Transceiver (AD2410) Two DuraClik connectors Debug Interface (JTAG and Trace) ICE-1000 emulator JTAG 10-pin 0.05 header JTAG and Trace 38-pin Mictor connector LEDs Eleven LEDs: one power (green), one board reset (red), eight general-purpose (amber) and one fault (red) Pushbuttons Four pushbuttons: one reset and three IRQ/Flag EI3 connector SMC EPPI SPORT SPI UART TWI TMR GPIO RESET GND/3.3V/5V output External power supply CE compliant 12V 1.5 Amps Power measurement 0.051-ohm resistors for measuring current drawYour ADSP-SC573 EZ-KIT package contains the following items.
