DSP軟件仿真及調(diào)試有了初步的了解與認(rèn)識，因?yàn)樽鰧?shí)驗(yàn)的時(shí)候都是按照實(shí)驗(yàn)指導(dǎo)書按部就班的，與真正的理解和掌握還是有些距離的。如果不重新加載，那么修改執(zhí)行程序后，其結(jié)果將不會改變。，顯示圖形出現(xiàn)問題，不能顯示，后來在Graph Title 把Input的大寫改為input，在對volume進(jìn)行編譯執(zhí)行后，就可以看到顯示的正弦波圖形了。如果按F10執(zhí)行程序，則程序在mian主函數(shù)中運(yùn)行，如果按F11，則程序進(jìn)入write_buffe函數(shù)內(nèi)部的程序運(yùn)行。，無需連接板卡和仿真器等硬件。但是一般無法構(gòu)造DSP中的外設(shè)，所以軟件仿真通常用于調(diào)試純軟件算法和進(jìn)行效率分析等。設(shè)置好的配置中只能有一項(xiàng)。，不是按實(shí)驗(yàn)書上的型號選擇，而是應(yīng)該按照實(shí)驗(yàn)設(shè)備上的型號去添加。=0x0。//
