Problems solved by technology

[0006] For the deficiencies in the prior art, the present invention proposes a display stream compression (DSC) encoder and a display engine, the display engine is integrated with a DSC encoder, and the DSC encoder multiplexes the internal memory of the display engine, which solves the problem of existing Display the problem of insufficient utilization of storage resources in the engine
The DSC encoder uses the existing write-back path in the display engine to write back the code stream data generated by compression into the memory, which solves the problem that the existing DSC encoder application scheme lacks effective verification means for the compressed data
The DSC encoder adopts block compression for the image, realizes a configurable and scalable multi-core parallel processing architecture, and solves the problem that the existing DSC encoder has insufficient ability to compress large-resolution images

Embodiment Construction

[0045] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention.

[0046] Such as Figure 4 As shown, a display engine includes an original image acquisition module 2 , an internal memory 3 , a write-back module 4 , and a display stream compression encoder 1 .

[0047] The memory bus is connected with the display stream compression encoder 1 through the original image acquisition module 2 . The display stream compression encoder 1 is also connected to the internal memory 3 . Moreover, the display stream compression encoder 1 is connected to the memory bus through the write-back module 4 .

[0048] The original image acquisition module 2 acquires the original image data from the original image storage module through the memory bus, and pre-processes the image data; the original image acquisition module 2 sends the processed original image data to the display stream compression encoder 1 . The display stream compression encoder 1 ...

Abstract

The invention discloses a display flow compression encoder and a display engine. The display engine comprises an original image acquisition module, an internal memory and the display flow compressionencoder. The original image acquisition module acquires original image data and transmitting the original image data to the display flow compression encoder. The display flow compression encoder compresses the original image data into code stream data and transmits out the code stream data. The display flow compression encoder multiplexes storage space of the internal memory. The display flow compression encoder is integrated in the display engine, the display flow compression encoder multiplexes the existing internal memory of the display engine, and thus, cost and area are saved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a display stream compression encoder and a display engine. Background technique [0002] Such as figure 1 As shown, the bandwidth requirement of the display link is proportional to the resolution of the display. A display with a large resolution requires a display link with a large bandwidth, and some display links do not have the bandwidth to support a display with a large resolution. Such as figure 2 As shown in Figure 1, video compression can be used to reduce bandwidth requirements, allowing the use of lower bandwidth display links to deliver digital video to large resolution displays. The high-resolution original image is compressed by the encoder and becomes a code stream with a small amount of data, which is output from the output interface to the input interface of the target device through the display link, and then sent to the display after being restored by...
