Supersampling or supersampling anti-aliasing (SSAA) is a technique to reduce aliasing (jagged edges) in computer graphics by rendering the image at a higher resolution and downsampling it. Learn about the motivation, methods, patterns and applications of SSAA in this Wikipedia article.
The Deltar was a hydraulic analogue computer used to design and execute the Delta Works, a project to protect the Netherlands from floods. It simulated tidal movements and river flows using electrical signals and mechanical devices.
Multisample anti-aliasing (MSAA) is a technique to remove jaggies in computer graphics by rendering multiple samples per pixel and combining them. Learn the definition, advantages, disadvantages, and sampling methods of MSAA.
Spatial anti-aliasing is a technique for minimizing the distortion artifacts when representing a high-resolution image at a lower resolution. Learn about the methods, examples, and applications of spatial anti-aliasing in digital signal processing, computer graphics, and digital photography.
Delta Computer Corporation was a short-lived American computer systems company active from 1986 to 1990 and originally based in Canton, Massachusetts. The company marketed a variety of IBM PC compatible systems featuring Intel 's 8088 , 80286 , and i386 processors under the Deltagold name.
The Paragon XP/S is a productized version of the experimental Touchstone Delta system that was built at Caltech, launched in 1992. The Paragon superseded Intel's earlier iPSC/860 system, to which it is closely related. The Paragon series is based on the Intel i860 RISC microprocessor. Up to 2048 (later, up to 4096) i860s are connected in a 2D grid.
Delta-sigma modulation is an oversampling method for encoding signals into low bit depth digital signals at a high sample-frequency. It is used in delta-sigma ADCs and DACs, which can achieve high quality and efficiency by correcting quantization errors and moving noise to higher frequencies.
In both November 2009 and June 2010, TOP500, the semiannual list of the world's top 500 supercomputers, named Jaguar as the world's fastest computer. In late October 2010, the BBC reported that the Chinese supercomputer Tianhe-1A had taken over the top spot, achieving over 2.5 quadrillion calculations per second , thereby bumping Jaguar to ...
