Embodiment

[0018] This embodiment is implemented by using a built-in multimedia processing unit in a flat-panel TV. Such as figure 2 shown. The multimedia terminal mainly includes two parts: a TV and a multimedia processing unit. The TV completes the processing, display and control functions of TV signals; the built-in multimedia processing unit completes the multimedia signal processing. The multimedia processor of this example adopts the XScale platform proposed by Intel Corporation, with PXA270 as the central processing unit.

[0019] The PXA270 processor is a solution based on the ARMv5TE architecture, using INTEL's XSCAL multimedia processing technology, with 7 state pipelines, a 32KB instruction cache, a 32KB data cache, and a 2KB "mini" data cache, which can be extended to 64MB. Data buffering; at the same time, built-in memory controller, internal and external bus widths are 16 and 32bit respectively, and supports 2.5V SDRAM, 64MB SDRAM is used in this example. PXA270 itself ...

Description

technical field [0001] The invention relates to signal processing technology, in particular to multimedia image signal processing technology. Background technique [0002] As the market environment continues to mature, more and more players such as MP4, mobile phones, PDAs, PMPs (Pocket Multimedia Players) that can play images begin to appear in the consumer electronics market, and are also welcomed by some users. However, due to the limitation of volume and storage capacity, relatively speaking, such devices have high storage cost, small screen size, poor playback clarity, and often have defects such as not being able to record information sources and not being able to manage files. [0003] In the technological tide of 3C integration, the topic of computer-centered or color TV-centered has been debated endlessly. But for now, TV has become the most suitable consumer electronics product because of its easier operation mode and wider popularity for ordinary consumers. Con...
