Embodiment

[0045] refer to Figure 10 , this platform can constitute an intelligent projection platform, the HDMI video input and output module 16 in the ZYNQ subsystem 1 realizes video input and DMD drive, the Kintex chip 21 in the Kintex subsystem 2 receives data through the camera 6, and then solidifies it in the Kintex chip 21 The advanced neural network algorithm completes functions such as gesture recognition and scene detection. For everyday projection equipment, the neural network unit solidified in the Kintex chip 21 can recognize user gestures and complete human-computer interaction. At the same time, the scene detection module solidified in the Kintex chip 21 can adjust the color saturation, brightness, sharpness and intelligent noise reduction for the corresponding scene, so as to improve the overall visual quality.

[0046] Specific working process: the video to be projected is input from the HDMI interface 161 of the HDMI video input and output module in the ZYNQ subsystem...

Description

technical field [0001] The present invention relates to chip prototype verification, in particular to a digital micromirror device drive chip FPGA prototype verification platform, which as a projection chip prototype verification platform includes ultra-large-scale chip prototype verification, intelligent projection chip prototype verification, and remote network video projection chip Prototype verification, etc. Background technique [0002] With the continuous development of integrated circuits, the demand for chip verification continues to increase. At present, the time spent in the chip verification stage accounts for more than 60% of the entire chip design cycle, so how to improve the efficiency and comprehensiveness of verification is a major problem facing current chip design. Traditional EDA simulation is a commonly used verification method at present, but it has the disadvantages of slow verification speed and incomplete verification. [0003] At the same time, wi...
