Intel’s MMX Speeds Multimedia: 3/5/96
The first major extension to the x86 instruction set since 1985 will greatly improve the venerable architecture’s handling of emerging multimedia applications. Collectively known as MMX, these 57 new instructions accelerate calculations common in audio, 2D and 3D graphics, video, speech synthesis and recognition, and data communications algorithms by as much as 8×. Overall, users will see a 50–...
متن کاملHigh Quality Video on MultiMedia PCs
Displaying broadcast video on a MultiMedia PC, implies the use of video format conversion (VFC) techniques, as computer displays and television receivers use quite distinct scanning rasters. VFC consists of spatial scaling, deinterlacing and picture rate conversion. Although scaling is rather straightforward, the other two tasks are far from trivial, and advanced motion compensated interpolatio...
متن کاملATM-based TH-SSMA network for multimedia PCS
Personal communications services (PCS) promise to provide a variety of information exchanges among users with any type of mobility, at any time, in any place, through any available device. To achieve this ambitious goal, two of the major challenges in the system design are: i) to provide a highspeed wireless subsystem with large capacity and acceptable quality-of-service (QoS) and ii) to design...

متن کاملCharacterization of MMX-enhanced DSP and Multimedia Applications on a General Purpose Processor
Proper use of native signal processing (NSP) instruction set enhancements can result in speedup for targeted applications. In this paper, we study the behavior of the X86 architecture's Multimedia Extension (MMX) instruction set on signal processing and multimedia algorithms and applications. In addition to quantifying speedup, we make comparisons based on detailed dynamic instruction pro ling....
