This is the Xilinx Dual Processor Reference Designs suite. The designs illustrate a few differentdual-core architectures based on the MicroBlaze™ and PowerPC™ processors. The designsillustrate various concepts described in the Xilinx White Paper WP262 titled, “DesigningMultiprocessor Systems in Platform Studio”. There are simple software applications includedwith the reference designs that show various forms of interaction between the two processors.

With the Altera Nios II embedded processor, you as the system designercan accelerate time-critical software algorithms by adding custominstructions to the Nios II processor instruction set. Using custominstructions, you can reduce a complex sequence of standard instructionsto a single instruction implemented in hardware. You can use this featurefor a variety of applications, for example, to optimize software innerloops for digital signal processing (DSP), packet header processing, andcomputation-intensive applications. The Nios II configuration wizard,part of the Quartus® II software’s SOPC Builder, provides a graphicaluser interface (GUI) used to add up to 256 custom instructions to theNios II processor

通過以太網(wǎng)遠(yuǎn)程配置Nios II 處理器 應(yīng)用筆記 Firmware in embedded hardware systems is frequently updated over the Ethernet. For embedded systems that comprise a discrete microprocessor and the devices it controls, the firmware is the software image run by the microprocessor. When the embedded system includes an FPGA, firmware updates include updates of the hardware image on the FPGA. If the FPGA includes a Nios® II soft processor, you can upgrade both the Nios II processor—as part of the FPGA image—and the software that the Nios II processor runs, in a single remote configuration session.
