具有AMBA之數位濾波器晶片設計與實作

一個高級微控制器匯流排架構(AMBA)架構的晶片系統(SOC)，一般來說包含了進階高性能匯流排(AHB)與進階周邊匯流排(APB)。高性能匯流排能提供高效率、多功能的傳輸模式，適用於高速的裝置；而進階周邊匯流排能提供比較簡單的傳輸介面，讓一些低功率的周邊裝置能互相連接。本論文將數位濾波器進行介面(Wrapper)的設計，使得其可以接連到高級微控制器匯流排架構上；以進階精簡指令集機器(ARM)模組當作系統控制者，去控制數位濾波器。數位濾波器使用在三角積分調變器的的後端電路，使用的濾波器有梳型濾波器以及有限脈衝響應濾波器，具有降頻(Down Sampling)的功能，主要濾除超出取樣頻率的訊號成分與量化誤差。使用TSMC之0.18-μm製程並經過電路合成(Synthesis)、自動佈局與繞線(APR)、設計規則(DRC)/電路比對(LVS)等流程製作出特殊應用積體電路(ASIC)的專用晶片，其邏輯閘數(Gate Count)約為60,000，動態功率為7.26mW。

A system on chip of AMBA(Advanced Microcontroller Bus Architecture) contains AHB(Advanced High-performance Bus) and APB(Advanced Peripheral Bus). AHB is the system bus and APB is the peripheral bus. AHB provides high-performance and multi-function transfer modes. It is applicable for high-speed devices. APB provides simple interface of the transmission and let low-power peripherals interlink. A wrapper of digital filter which can connect with AMBA is designed. Using the ARM module treats as the controller and controls the digital filter. The digital filter makes use of after the Sigma-Delta Modulator. The design uses Comb Filter and FIR Filter. It has the function of down sampling and filters out signals and quantification differences of exceeding frequency mainly. The TSMC 0.18-μm CMOS technology is selected to implement the ASIC by passing through the procedure of Synthesis、APR(Auto Place and Route)、DRC(Design Rule Check)、LVS(Layout Versus Schematic). After simulation, the proposed ASIC performs with the gate count of 60,000, the dynamic power of 7.26mW.
