【正文】 realtime signal processing requirements, requiring digital signal processing of mon operations performed as quickly as possible. This determines the DSP features and key technologies. Suitable for digital signal processing techniques: DSP indulgence multiplier, accumulator, special address generator, leading overhead loops。 easy integration。 facilitate the adjustment of the processor factor to achieve adaptive filter。 can be used to frequency of very low signal. Keywords: Typical characteristics。 Program flow 安徽工程大學(xué)機(jī)電學(xué)院畢業(yè)設(shè)計(jì) 3 目 錄 基于 DSP2812 的實(shí)驗(yàn)開發(fā)板設(shè)計(jì) ........................................................................................... 1 引 言 ........................................................................................................................................ 6 第 1 章 緒論 .............................................................................................................................. 7 課題背景及實(shí)際意義 ...................................................................................................... 7 DSP 芯片 的國內(nèi)發(fā)展概況 .............................................................................................. 7 本課題的主要研究內(nèi)容 .................................................................................................. 8 第 2 章 的安裝 與 配置 ................................................................................................ 9 系統(tǒng)的安裝 ......................................................................................................... 9 仿真器的安裝 ................................................................................................................... 9 系統(tǒng)的配置 ....................................................................................................... 12 本章小結(jié) ........................................................................................................................ 14 第 3 章 基于 DSP2812 的實(shí)驗(yàn)開發(fā)板的硬件設(shè)計(jì) .............................................................. 15 TMS320F2812 芯片 ....................................................................................................... 15 電源模塊硬件設(shè)計(jì) ........................................................................................................ 16 流水燈實(shí)驗(yàn)的硬件設(shè)計(jì) ................................................................................................ 17 獨(dú)立按鍵掃描的硬件設(shè)計(jì) ............................................................................................ 17 四位數(shù)碼管實(shí)驗(yàn)的硬件設(shè)計(jì) ........................................................................................ 17 外部中斷實(shí)驗(yàn)硬件設(shè)計(jì) ................................................................................................ 18 本章小結(jié) ........................................................................................................................ 18 第 4 章 基本實(shí)驗(yàn)內(nèi)容 ............................................................................................................ 19 GPIO 應(yīng)用：流水燈實(shí)驗(yàn) .............................................................................................. 19 實(shí)驗(yàn)?zāi)康?
