由於驅動程式為應用軟體與硬體裝置之溝通橋樑,因此驅動程式本身之架構可粗略地分為三個部分:作業系統相關之溝通介面(OS dependent specifications),包含各種系統呼叫、核心函式等;硬體裝置相關之設定(HW dependent specifications)包括I/O暫存器設定與位址空間轉換等;以及支援硬體裝置特定功能或行為之韌體部分(User defined firmware)。使用者必須對這三個部分作描述,作為驅動程式自動產生器之輸入資訊。而驅動程式自動合成方法則是以Template-Based之設計方式,建立出程式樣板資料庫,根據使用者所於圖形化介面中所描述之輸入資訊,將適當之樣板組合成符合需求之驅動程式,因此可以快速產生所需之驅動程式,若要對驅動程式做修改時,也只需抽換部分樣板即可。此外,對於軟硬體之溝通方式,規劃了四種軟硬體溝通方式,能夠根據不同IP之特性,產生最合適之溝通方式,以達到提升系統效能之目的。最後,以若干軟硬體共設計之系統驗證驅動程式自動產生器,並且為各系統分別產生不同溝通方式之驅動程式,進而分析各系統使用不同溝通方式時之系統執行效能、以及軟硬體溝通效能。

This paper presents the framework of a baseline driver generator to facilitate the driver development for fast IP integration in SoC designs. The proposed baseline driver generator can handle both character and block type devices and is found useful for the integration of non-standard IPs. The driver generator can generate a baseline driver contains not only basic driver setting, hardware access/control functions and file operations but also interrupt and DMA functions.
Since application programs cannot have direct access to the hardware (IP) in the presence of OS, a driver is employed to serve the purpose. The code of a driver can be roughly divided into 3 sections. The first section is OS dependent and handles tasks such as interfacing with OS system calls and using OS kernel functions. The second section is hardware dependent settings and needs the knowledge of memory map and interface design. The third section is considered as the user defined firmware supporting specific functions needed for the driver operations. The proposed driver generator provides users with a GUI to capture these 3 specifications. Various pre-developed code templates can be instantiated subject to the specifications. The code templates are parameterized and users can characterize a desired driver through the parameter settings via GUI. Some design examples on the driver generation tool and various HW/SW codesign examples are presented to demonstrate the effectiveness of the proposed automation methodology.
