數據緩沖單元
英文
dbu data buffer unit-
Is the length in bytes of the data buffer
是數據緩沖區的長度，以位元組為單位。By default mmus are implemented and they are constructed of 64 - entry hash based 1 - way direct - mpped data tlb and 64 - entry hash based 1 - way direct - mapped instruction tlb
默認的存儲器管理單元實現由基於64個散列入口的單通道直接映射的數據后備式轉換緩沖區和基於64個散列入口的單通道直接映射的指令后備式轉換緩沖區組成。Concretely, on the basis of describing the communication specification of arinc 429 with enhanced parallel port ( epp ), the standard and the module application of dsp and cpld, the thesis has proposed the design of the arinc 429 technology based on dsp system. at first, the function and the application of each module of the system and the operation principle of high - performance cmos bus interface circuit hs - 3282 chip which forms the main body of the data diversion of the interface module are introduced. secondly, the hardware structure of the interface module is described in detail, mainly including data latch and buffer circuit, choice circuit of transmission rate, etc. and then the design philosophy and flow charts of the software are fully discussed, such as the basic requirement of software, the design and realization of the function
本文在簡單的論述了pc並口協議（ epp ）與dsp之間的通信方法、 cpld模塊邏輯控制應用和arinc429的通訊規范的基礎上，給出了基於dsp的arinc429通訊介面的設計方案:對通訊板中各模塊的功能和應用以及構成數據轉換主體的總線介面晶元hs - 3282的工作原理做了說明;介紹了本設計所用的dsp和cpld的功能概況;詳細敘述了通訊板介面模塊的硬體結構設計，其中，對數據緩沖電路、數據傳輸速率選擇電路、邏輯控制電路等各關鍵點做了重點介紹;具體闡述了軟體設計思想及流程圖，包括軟體的基本要求和功能的設計與實現;接著從埠譯碼單元、 i / o通道、電平轉換電路等方面進行了介面模塊的軟、硬體調試;最後，給出了測試結果，對研製工作做了總結，對本設計的優缺點各做了評述。The content of the electricity transforming of the system with profibus includes the designing of signal detecting and dealing system, the developing of the major cache unit machine control, the integration of the system diagnosis and data information, and the subordinate station diagnosis function
