With the expansion of ASIP application,the design cycle, design cost and other nonfunctional requirements of ASIP are being more and more important .And the design of pipeline structure is one of the most plicated part in ASIP design, traditional ASIP pipeline design method has been couldn39。 Application Specific Instruction Processor 。 Petri Net Markup Language Thesis : Applied Research目錄 I 目 錄 1 緒論 ......................................................................................................................................... 1 選題的背景 ......................................................................................................................... 1 研究意義 ............................................................................................................................. 1 國內(nèi)外研究現(xiàn)狀分析 ......................................................................................................... 2 研究目標(biāo)及主要研究內(nèi)容 ................................................................................................. 3 論文章節(jié)安排 ..................................................................................................................... 5 2ASIP 設(shè)計方法學(xué) .................................................................................................................... 7 “描述 綜合”方法學(xué) ......................................................................................................... 7 描述模型 .................................................................................................................... 8 模型 ......................................................................................................................... 9 ...................................................................................................................... 9 邏輯綜合 .................................................................................................................. 13 本章小結(jié) ........................................................................................................................... 14 3 基于 OTA 的 ASIP 架構(gòu)研究 .............................................................................................. 15 架構(gòu) ........................................................................................................................... 15 ASIP 指令集 ..................................................................................................................... 16 ISA ....................................................................................................................... 16 專用指令 .............................................................................................................. 18 系統(tǒng)結(jié)構(gòu)描述 .......................................................................................................... 19 單周期處理器 ............................................................................................................... 19 多周期處理器 ............................................................................................................... 21 流水線處理器 ............................................................................................................... 23 本章小結(jié) ............................................................................................................................ 26 4Petri網(wǎng)流水線建模 ................................................................................................................ 27 ............................................................................................................ 32 模型 ........................................................................................................................ 33 武漢紡織大學(xué)碩士學(xué)位論文 模型 ....................................................................................................................... 33 模型 ...................................................................................................................... 34 基于 PNML 的 Petri 網(wǎng)流水線模型描述 ........................................................................ 35 .................................................................................................... 44 單元邏輯綜合 ............................................................................................................ 44 單元邏輯綜合 ........................................................................................................... 44 單元邏輯綜合 ....................................................................................................... 45 邏輯綜合 .............................................................................................................. 45 邏輯綜合 ................................................................................................................. 46 本章小結(jié) ...................................................................
