  • NIOSII用户定制指令

    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

  • 多径信道下OFDM系统定时同步算法

    文中在pre-FFT定时同步算法的基础上提出一个新的定时同步算法及其改进算法,该算法利用规则集对相关函数和导函数优化的方法得以进一步减小估计方差,本文在给出其推导过程的基础上给出了仿真结果,并与相关算法进行比较,结果表明新算法的定时估计精度较高且具有一定的鲁棒性。

  • 远程配置Nios II处理器应用笔记

         通过以太网远程配置Nios II 处理器 应用笔记 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.
