面向Eclips的NIOS ii軟件構(gòu)建工具手冊(cè)
The Nios® II Software Build Tools (SBT) for Eclipse™ is a set of plugins based on the
Eclipse™ framework and the Eclipse C/C++ development toolkit (CDT) plugins. The
NIOS ii SBT for Eclipse provides a consistent development platform that works for all
NIOS ii embedded processor systems. You can accomplish all NIOS ii software
development tasks within Eclipse, including creating, editing, building, running,
debugging, and profiling programs.

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(hù)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.
NIOS ii 系列處理器配置選項(xiàng):This chapter describes the Nios® II Processor parameter editor in Qsys and SOPC Builder. The NIOS ii Processor parameter editor allows you to specify the processor features for a particular NIOS ii hardware system. This chapter covers the features of the NIOS ii processor that you can configure with the NIOS ii Processor parameter editor; it is not a user guide for creating complete NIOS ii processor systems.
