使用NIOS II軟件構建工具 This chapter describes the NIOS® II Software Build Tools (SBT), a set of utilities and scripts that creates and builds embedded C/C++ application projects, user library projects, and board support packages (BSPs). The NIOS II SBT supports a repeatable, scriptable, and archivable process for creating your software product. You can invoke the NIOS II SBT through either of the following user interfaces: ■ The Eclipse™ GUI ■ The NIOS II Command Shell The purpose of this chapter is to make you familiar with the internal functionality of the NIOS II SBT, independent of the user interface employed.

通過以太網遠程配置NIOS II 處理器 應用筆記 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.

NIOS II 軟件開發人員手冊中的緩存和緊耦合存儲器部分 NIOS® II embedded processor cores can contain instruction and data caches. This chapter discusses cache-related issues that you need to consider to guarantee that your program executes correctly on the NIOS II processor. Fortunately, most software based on the NIOS II hardware abstraction layer (HAL) works correctly without any special accommodations for caches. However, some software must manage the cache directly. For code that needs direct control over the cache, the NIOS II architecture provides facilities to perform the following actions:

NIOS II定制指令用戶指南：With the Altera NIOS II embedded processor, you as the system designer can accelerate time-critical software algorithms by adding custom instructions to the NIOS II processor instruction set. Using custom instructions, you can reduce a complex sequence of standard instructions to a single instruction implemented in hardware. You can use this feature for a variety of applications, for example, to optimize software inner loops for digital signal processing (DSP), packet header processing, and computation-intensive applications. The NIOS II configuration wizard,part of the Quartus® II software’s SOPC Builder, provides a graphical user interface (GUI) used to add up to 256 custom instructions to the NIOS II processor. The custom instruction logic connects directly to the NIOS II arithmetic logic unit (ALU) as shown in Figure 1–1.
