Embodiment Construction

[0022] refer to figure 1 , the present invention takes the programmable device FPGA as the core, and the FPGA includes an input timing controller, FIFO1, FIFO2, an image scaler, an output timing controller and a high-speed data storage controller. These module codes (software) are burned into the FPGA configuration chip, and are automatically loaded into the programmable FPGA after power-on.

[0023] The input timing controller is based on the synchronization signal and timing requirements of the input video signal to ensure that the effective image data can be smoothly written into the FIFO for buffering; the output timing controller is the synchronization signal, field synchronization signal and line synchronization signal necessary to generate the output image , to ensure that the data of the output image is consistent with the timing, so that the image can be displayed correctly on the display.

[0024] As for the control design of the two sequential controllers, proceed ...

Abstract

The invention discloses an ARM (Advanced RISC (reduced instruction set computing) Machines) signal extension display device, which comprises an ARM9 system circuit used for generating ARM image signals, a programmable device FPGA (Field Programmable Gate Array) used for controlling the zoom of graphics, a high-speed data memory used for storing input digital video data frames and output digital video data frames, an output digital video signal converter used for decoding the digital video signals to signals capable of being identified by an external display device, and an LCD (Light Crystal Display) screen used for converting the digital video signals into information capable of being directly sensed by the eyes of a human body. According to the ARM signal extension display device, the resolution of ARM signals is extended, thereby facilitating to observe the graphics and increasing the performance of the graphics.

Description

technical field [0001] The invention relates to image information processing technology, in particular to a device for expanding the resolution of a reduced instruction set microprocessor (ARM) signal to a higher display resolution. Background technique [0002] In the information society of the 21st century, digital display technology has developed rapidly, and digital integrated circuits are widely used. ARM, as the world's largest IP provider of embedded chip technology, leads the development trend of embedded technology in the industry. Its IP has become a technical standard and development platform adopted by many chip design companies. Therefore, the SOC based on ARM CORE has become the focus of embedded processor development. Therefore, the LCD controller can be implemented through ARM to complete the control of the embedded LCD screen. If the TFT screen is used to support the display, its resolution is low. For Observation and grasp of graphic details are limited, s...
