  1. 數位信號處理器--TI DSP 10/21/03

  2. Outline • TI DSPs’ overview • Features of TMS320C6711 • Software Development Tool Flow • DSP/BIOS • Code Compose Studio (CCS) • Tools for Debug

  3. TI DSPs’ overview • Why DSP Processor ? • Mathematical calculate vs. data manipulation • Math Calculation • Addition A+B=C • Multiplication AxB=C • Sum of Production a0x0+a1x1+a2x2…+anxn • Data Manipulation • Data Move AB • Value testing , sorting , and searching • Real-time processing vs. off-line processing • Real-time Processing: 輸入資料進入的同時也輸出訊號 • Off-line Processing 大量資料輸入後一起處理 • Massively computational requirements • 應用於通訊系統、多媒體系統或智慧型控制系統

  4. TI DSPs’ overview (cont’) • Common Features of DSP Processor • Specialized Addressing Modes • Circular buffer , Bit-Reversed addressing for FFT • Fast Multiply-accumulate (MAC) • Specialized Program Control • High performance Interrupt handling • Pipeline structure to perform one instruction per cycle • On-chip Peripherals and I/O Interface • Direct Memory Access (DMA) • Multichannel Buffered Serial Ports (McBSP) • External Memory Interface (EMIF) • Timers • On-chip A/D , D/A converters • Clock generators

  5. TI DSPs’ overview (cont’) • TI TMS320 DSP Platforms • Control Optimized：TMS320C2000 DSP Platform • 以控制為主，類似於MCU（Micro Control Unit）。 • Best Power Efficiency：TMS320C5000 DSP Platform • 低耗電但速度較慢。 • 多應用於如手機、PDA、數位相機等攜帶式產品上。 • High Performance：TMS320C6000 DSP Platform • 以高效能為主。 • 主要市場目為Broadband、Wireless、3G、Image等市場。

  6. TI DSPs’ overview (cont’) • The Evolution of DSP

  11. DSP/BIOS：Real-Time Kernel BIOS provides: • System Configuration (Timer、PLL、wait states…etc.) • Peripheral setup and use configuration • Priority based scheduling (H/W、S/W) • Creation of interrupt vectors • Graphical real-time analysis • 利用DSP/BIOS圖形化介面設定相關參數 • 不需自行撰寫Link command file and vector.asm

  12. Code Compose Studio (CCS) • 提供使用者程式開發介面 • 程式編譯與連結 (Build ) • 載入程式碼至DSP發展板 (Program Load) • 提供完整除錯工具與環境

  13. Tools for Debug • 中斷點設定 • 探測點設定 • 記憶體與暫存器內容值 • 圖形分析 (時域/頻域) • 影像擷取(CCD) • 利用DSP/BIOS • CPU效能分析 • 軟體邏輯分析儀 • 工作執行時間分析
