【正文】 是一種適合完成數(shù)字信號處理運(yùn)算的處理器。 數(shù)字信號處理是利用計(jì)算機(jī)或?qū)Ｓ锰幚碓O(shè)備，以數(shù)字形式對信號進(jìn)行采集，變換，濾波，固執(zhí)，增強(qiáng)，壓縮，識別等處理，已得到符合 人們需要的信號形式。 關(guān)鍵詞 ： 典型特征；體系結(jié)構(gòu)；程序流程 王 輝：基于 DSP2812 的實(shí)驗(yàn)開發(fā)板設(shè)計(jì) 2 The experimental development board design based on DSP2812 Abstract This design is the DSP (2812) Minimum system design, DSP is a widely used but many disciplines involved in many areas of emerging disciplines. We often say that the DSP refers to the digital signal processor. Digital Signal Processor is a plete crosssignal processing for the processor. Since the 60s of the 20th century, with the puters and the rapid development of information technology, DSP technology and the rapid development emerged. In the past twenty years time, digital signal processing in munications and other fields has been very widely used. Digital signal processing is to use a puter or dedicated processing equipment to collect the signal in digital form, transform, filter, stubborn, enhancement, pression, recognition processing needs of the people has been the signal form. Digital signal processing theory is based on a number of sciencebased, its scope and wide. For example, in science, calculus, probability and statistics, stochastic processes, numerical analysis, digital signal processing are the basic tools. And work theory, signals and systems, control theory, munication theory, fault diagnosis, etc., are closely related, can be said that digital signal processing is to many classical theoretical system as its theoretical basis, but also to bee a new discipline theoretical basis. DSP is mainly used in digital signal processing, designed to meet 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。 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? ................................................................................................................. 19 實(shí)驗(yàn)要求 ................................................................................................................. 19 實(shí)驗(yàn)設(shè)備 ................................................................................................................. 19 實(shí)驗(yàn)內(nèi)容 ................................................................................................................. 19 實(shí)驗(yàn)方法和步驟 ..................................................................................................... 20 實(shí)驗(yàn)參考程序 ......................................................................................................... 20 實(shí)驗(yàn)預(yù)習(xí)要求 .......................................................................................................... 21 GPIO 應(yīng)用：獨(dú)立按鍵掃描實(shí)驗(yàn)（流水燈觀察） ....................................................... 21 實(shí)驗(yàn)?zāi)康? ................................................................................................................. 21 實(shí)驗(yàn)要求 ................................................................................................................. 21 實(shí)驗(yàn)設(shè)備 ................................................................................................................. 21 實(shí)驗(yàn)內(nèi)容 ................................................................
