Includes single cycle MAC operations, and hardware based native Jazelle Java Byte-codeĮxecution. The ARM926EJ-S also has a hardware based set of DSP instruction extensions, which Virtual memory capabilities needed to support the programming demands of modern The NXP implementation uses a ARM926EJ-S CPU core with a Harvard architecture, 5-stage pipeline, and an integrated Memory Management Unit (MMU). NXP achieved these goals using a 90 nano-meter process to implement an ARM926EJ-S CPU core with a vector floating point co-processor and a large set of standard peripherals. The Phytec board data can be found on: The details of the micro-conroller can be obtained from: The LPC0/50 embedded micro-controllers are designed for low power, high performance applications. With the choice of the Phytec board came the NXP LPC3250-A9 micro-controller.
#INTERFACE MEMORY PROCSSOR CODE#
The obvious choice was thus to go for Linux instead of writing code on the bare metal of the ARM processor.The Phytec development system comes with a Linux port.A ZYNQ connecting to its FPGA Block-RAM is a topic of another article.
A board with a processor-less FPGA is chosen because the successful connection between the external processor and FPGA must be proven.Use an available Xilinx Development board.The Phytec ph圜ORE-LPC3250 development board was chosen.Use off the shelf micro-controller hardware.To prove this concept some design decisions were taken: The FPGA connects via the External Memory Interface (EMI) to the ARM processor. Figure 1shows the setup of an example video design.įigure 1: Micro-controller – FPGA video application. The solution provided is to use one Chip Select area of the micro-controllersĮxternal Memory Controller (EMC) in SRAM mode and connect this to theįPGA. Using an FPGA as high speed – parallel video processing engine and aĭedicated ARM micro-controller as human interaction interface. Because ARM devicesĪre so widely used across the processor sector there is a variation ofĪn application that caused this note to be written was a video application Its versatility, many manufacturers implement it as the core of theirĪpplications (Including he ZYNQ family of devices). Parallel processing tasks while the ARM micro-controller is widely used due to IntroductionĪn FPGA is primary used for computationally intensive, high-speed and/or The micro-controller mostly uses the FPGA as a pre-processing high-speed, Or as extended multi-peripheral (USB, LCD, Keyboard, etc.) device. The FPGA can use the micro-controller as process controller This note provides a way to hook a FPGA to an off the shelf available ARM Of course a standalone micro-controller can also be used in combination with a ZYNQ FPGA. 5.2 Build U-boot, Linux kernel and root file system:Īlthough there is the versatile and powerful ZYNQ extensible processor-centric architecture with its on board dual-core Cortex-A9 ARM processorĭevices, sometimes it is necessary to use a standalone micro-controller inĬombination with a processor-less FPGA.
