Embodiment Construction

[0066] Overall system design:

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

[0068] ARM hardware design

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

[0070] The design adopts a layered structure, layered design, and layered implementation. The internal implementation of each layer is transparent to other layers. The lower layer can only be called by the upper layer in one direction. The functions between each layer are clearly defined and the interfaces are clear. The hardware layer is the hardware platform on which the entire embedded operating system and applicatio...

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 is used 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 an IIC 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 to realize 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 automotive electronic instruments, and in particular relates to a hardware system architecture of an intelligent full-graphics automotive instrument. Background technique [0002] The level of electronic control and informatization of automobiles is constantly improving, and at the same time, various vehicle-mounted 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 a large amount of complex information under the new trend. Upgrading the traditional instrumentation system to a new generation of intelligent full graphics system can well meet the needs, and has the advantages that traditional mechanical or electromechanical instruments cannot replace. [0003] "Intelligent full-graphic automotive instrumentation" realizes a multi-functional intelligent full-graphical automotive instr...
