TMS320C6711D 浮點數(shù)字信號處理器

數(shù)據(jù):

描述

TMS320C67x ??的DSP(包括TMS320C6711,TMS320C6711B,TMS320C6711C,TMS320C6711D設(shè)備)構(gòu)成浮點DSP家族在TMS320C6000? DSP平臺。在C6711,C6711B,C6711C和C6711D設(shè)備都是基于高性能,先進的超長指令字(VLIW)架構(gòu)的德州儀器(TI)開發(fā),使這些DSP的多通道多功能應(yīng)用的絕佳選擇。

C6711D器件的時鐘頻率為200 MHz,時鐘速率高達1200萬次(MFLOPS),時鐘頻率為250 MHz,最高可達1500 MFLOPS,高效DSP編程挑戰(zhàn)的有效解決方案。 C6711D DSP具有高速控制器的操作靈活性和陣列處理器的數(shù)字能力。該處理器具有32個32位字長的通用寄存器和8個高度獨立的功能單元。八個功能單元提供四個浮點/定點ALU,兩個定點ALU和兩個浮點/定點乘法器。 C6711D每個周期可以產(chǎn)生兩個MAC,總共400 MMACS。

C6711D DSP還具有專用硬件邏輯,片上存儲器和其他片上外設(shè)。

< p> C6711D設(shè)備使用基于緩存的兩級架構(gòu),并具有功能強大且多樣化的外設(shè)集。 1級程序高速緩存(L1P)是32-Kbit直接映射高速緩存,1級數(shù)據(jù)高速緩存(L1D)是32-Kbit 2路組關(guān)聯(lián)高速緩存。 2級內(nèi)存/高速緩存(L2)由512-Kbit的內(nèi)存空間組成,在程序和數(shù)據(jù)空間之間共享。 L2內(nèi)存可以配置為映射內(nèi)存,緩存或兩者的組合。外圍組包括兩個多信道緩沖串行端口(McBSP的),兩個通用定時器,主機端口接口(HPI),和一個無縫外部存儲器接口(EMIF)能夠連接到SDRAM,SBSRAM和異步外圍設(shè)備。

C6711D有一套完整的開發(fā)工具,包括:一個新的C編譯器,一個簡化編程和調(diào)度的匯編優(yōu)化器,以及一個Windows?調(diào)試器接口,用于查看源代碼執(zhí)行情況。
