A Programmable Multi-Format Video Decoder

Flexible Multi-Core Platform for a Multiple-Format Video Decoder

Architecture Considerations for Multi-Format Programmable Video Processors

Many different video processor architectures exist. Its architecture gives a processor strength for a particular application. Hardwired logic yields the best performance/cost, but a programmable processor is important for applications that support multiple coding standards, proprietary functions, or future changes to application requirements. Programmable video processor architectures achieve b...

Programmable Accelerators for Reconfigurable Video Decoder

Practically all modern video coding standards such as H.264, MPEG-4 and VC-1 are based on hybrid transform based block motion compensated techniques, that employ almost the same coding tools. The same approach is used with numerous non-standard proprietary codecs, with decoders available via Internet as browser plugins. For mobile devices power efficient hardware accelerators have been develope...

A DSP Based Multi-Format Video Decoder for an IP Set-Top Box

In this paper, the implementation of a digital signal processor (DSP) based multi-format decoder for an IP set-top box is described. Using several software optimization techniques, the multi-format decoder has been fitted into a TMS320DM641 DSP @ 480 Mhz. Starting from a native C code implementation, a six-step software optimization process has been applied to improve the decoder performance. C...

A single-chip MPEG-2 MP@ML audio/video encoder/decoder with a programmable video interface unit

We present a single-chip, MPEG-2 Main Profile at Main Level, audio and video encoder and decoder. It combines a RISC core, a 24-bit DSP, video and audio interface units, and several dedicated processing units. A programmable video interface unit supports multiple modes of preand post-processing and on-screen display (OSD). The codec has been implemented using a standard-cell library in 0.18 m C...
