Embodiment Construction

[0066] Overall system design:

[0067] Such as figure 1 As shown, the hardware system adopts the ARM+FPGA architecture, where ARM is mainly used for data acquisition and system control, and FPGA is mainly used for video processing and graphics drawing and display. The specific hardware design is detailed as follows:

[0068] ARM hardware design

[0069] Such as figure 2 Shown is the overall design of the ARM part, which is mainly composed of a hardware layer, a hardware driver layer, a hardware abstraction layer, an operating system layer, and an application program layer.

[0070] In the design, layered structure, layered design, and layered implementation are adopted. The internal implementation of each layer is transparent to other layers, and the lower layer can only be called one-way by the upper layer. The functions between the layers are clearly defined and the interface is clear. The hardware layer is the hardware platform on which the entire embedded operating system and app...

Abstract

The present invention relates to a hardware system structure of intelligent wholly-graphic vehicle instrument, and consists of a microprocessor ARM and a field programmable gate array FPGA. The ARM isused for data acquisition and system control; the FPGA is used for video processing and graphic depiction display. The hardware system structure is characterized in that the FPGA and the ARM adopt anIIC mode or a shared memory for communication; the FPGA module is arranged outside, with an AVALON / SRAM serving as a static random access memory SRAM of the ARM processor; the graphic data transmitted from the ARM processor is stored in a synchronous dynamic random access memory SDRAM; the display and drawing array VGA display is driven according to the instructions of the ARM processor, so as torealize the functions of multilayer aliasing display, picture-in-picture display and point-line plotting. The hardware system adopts the highly efficient and flexible ARM+FPGA structure; the ARM is used for data collection, collation, analysis, storage and other functions; and the FPGA field programmable gate array is used for displaying the user interface.

Description

Technical field [0001] The invention belongs to the field of automobile electronic meters, and specifically relates to a hardware system architecture of an intelligent full-graphic automobile instrument. Background technique [0002] The degree of electronic control and informatization of automobiles is constantly improving, and various on-board equipment and information services are also increasing. As a traditional information display terminal, the instrument system has the potential to meet the new requirements of displaying large amounts of complex information under the new trend. Upgrading the traditional instrument system to a new generation of intelligent full-graphics system can well meet the demand, and has the advantage that traditional mechanical or electromechanical instruments cannot be replaced. [0003] "Intelligent full-graphic car instrument" realizes a multi-functional intelligent full-graphic car instrument system on a self-developed software and hardware platfo...
