Embodiment Construction

[0020] Various embodiments will be described below with reference to the accompanying drawings.

[0021] Generally, according to an embodiment, a graphics processing unit includes a host interface, a memory controller, multiple processing cores, an operation control unit, a video signal output interface, and an audio signal output interface. The host interface is configured to receive video data and audio data from the host. The memory controller is configured to store the received video data and audio data in memory. Multiple processing cores are connected to memory. The arithmetic control unit is configured to analyze a frame of the video data on the memory to detect a feature of the video data by using at least one first processing core among the plurality of processing cores, and to process the video data by using at least one second processing core among the plurality of processing cores. A core applies processing related to the detected characteristics of the video dat...

Abstract

The present invention provides a graphics processing unit and information processing apparatus. According to one embodiment, a graphics processing unit 105 detects characteristics of video data by analyzing frames of the video data by using at least one first processing core 204 of a plurality of processing cores 204, and applies a process, which is associated with the detected characteristics of the video data, to audio data on a memory 105A, by using at least one second processing core 204 of the plurality of processing cores 204. The graphics processing unit 105 includes an audio signal output interface 207 and outputs an audio signal corresponding to the audio data, to which the process has been applied, to a sound device.

Description

technical field [0001] Embodiments described herein relate generally to graphics processing units and information processing devices using graphics processing units. Background technique [0002] Generally, in an information processing device such as a personal computer, a graphics processing unit (GPU) is used in order to improve the image rendering performance of the information processing device. Most modern GPUs include multiple processing cores that can operate in parallel and can perform operations such as 2D or 3D graphics operations at high speed. [0003] On the other hand, processing of audio data (also called "sound data") in an information processing device is generally performed by a digital signal processor (DSP) called a "sound controller". However, in general, the operation processing performance of DSP is relatively low. Therefore, it is difficult for DSP to perform advanced processing on audio data alone. [0004] In addition, recently, media processing ...
