Problems solved by technology

Although there are already many compression algorithms for rendering files that can achieve high compression ratios, these compressed files often take up a lot of resources when decompressed by software. The higher the compression ratio, the longer the decompression time and the greater the overhead.

Embodiment Construction

[0055] The RIB rendering compressed file is in ASCII encoding format, and the data content is composed of commands + parameters. In an example, "Option"limits""int bucketsize"[16 16]", Option is a state of graphics, which means global sharing Graphics state, the change of the frame will not change the state information; in another example, "Attribute"identifier""name""_spotLight1_spotLightShape1"", the current state is represented by Attribute, including the light source, the material of the geometry and other information; there are other such as Display commands in the global state; these commands and parameters contain all the information needed for rendering. In a RIB rendering compressed file, the data content appears repeatedly in the form of command calls, which has high compressibility; in the RIB rendering compressed file stream of the same series of rendering tasks, the data content is called by the same command The form repeats many times, and the parameters of the c...

Abstract

The invention discloses a RIB rendering compressed file FPGA compression / decompression system and hardware decompression method, including a user end, the user end is used to transmit the RIB rendering compressed file to a compression module, and the compression module is the RIB rendering compressed file from the user through the wide area network The preprocessing module before the client is transmitted to the server is used to compress the RIB rendering compressed file streamed from the client to the server. The RIB rendering compressed file is compressed in batches by the compression module and then sent to the FPGA hardware decompression module through the WAN, and decompressed by the FPGA hardware The module reads the compressed data, which is used to realize the hardware decompression of the streamed RIB rendering compressed file, and outputs the decompression result to the server. The server is used to access the rendering unit to complete the subsequent rendering work, improve the decompression speed, and reduce the decompression power consumption during the process.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to an FPGA compression / decompression system and hardware decompression method for RIB rendering compressed files. Background technique [0002] Animation and video rendering is the process of using software to build a model of information such as materials, textures, and light in the scene to generate continuous and realistic images. Among them, the RIB rendering compressed file is a script file of the rendering software RenderMan, which stores script commands belonging to the RenderMan interface, and is also called the RIB protocol. RenderMan's application programming interface has a series of functions for transferring data from other applications, including geometric attributes of the scene, rendering attributes, etc. The renderer will accept these data and read the control information inside to complete the follow-up work, while RIB rendering compression The...
