Abstract: When people want portable music, they usually rely on battery-powered audio devices. With a bit of engineeringblood (or curiosity) running in your veins, it is not difficult to build a wireless Bluetooth® stereo audio system that can becontrolled with Any device that has a Bluetooth connection and a music player

Nios II 軟件開(kāi)發(fā)人員手冊(cè)中的緩存和緊耦合存儲(chǔ)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:

This application note describes how to retrieve user-defined data from Xilinx configurationPROMs (XC18V00 and Platform Flash devices) after the same PROM has configured theFPGA. The method to add user-defined data to the configuration PROM file is also discussed.The reference design described in this application note can be used in Any of the followingXilinx FPGA architectures: Spartan™-II, Spartan-IIE, Spartan-3, Virtex™, Virtex-E, Virtex-II,and Virtex-II Pro.
