Nios II 軟件開發(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:
如果用戶現(xiàn)有的是 Protel99SE 。ProtelDXP,Protel2004 版本: 1 在powerpcb 軟件的中打開 PCB 文件,選擇導(dǎo)出 ASCII 文件(export ascii file) ,ascii file 的版本應(yīng)該選擇 3.5 及以下的版本。 2 a 在 Protel99SE 。ProtelDXP , 選擇 File->Import->在出現(xiàn)的對(duì)話框中,選擇文件類型中的PADS Ascil Files (*.ASC)輸入對(duì)應(yīng)文件即可 1.powerpcb-->export ascii file--->import ascii file with protel99 se sp5(u must install padsimportor that is an add-on for 99sesp5 which can downloan from protel company ). 2.powerpcb-->export ascii file-->import ascii file in orcad layout-->import max file(orcad pcb file)with protel 99 or 99se.
