In order to preserve the MOS Technology 6502 central processing unit, the team at Visual 6502 had to reverse engineer the chip.
HP Labs, HP's central research arm, said it has made advancements that could allow future computers to perform logic on the chip that stores the data, rather than on a central processing unit.
Deployed just two weeks ago, Titan is the fastest, most powerful, and most energy-efficient of a new generation of supercomputers that breach the bounds of "central processing unit" computing.

An essential distinction of the GPU architecture from the Central Processing Unit (CPU) architecture causes new difficulties as well as new optimization capabilities.
Pseudo-random number generators for Monte Carlo simulations on Graphics Processing Units
While implementation of the algorithm on the central processing unit such discarding is “virtual”, because lag table fits in processor cache very well, as a rule.
Pseudo-random number generators for Monte Carlo simulations on Graphics Processing Units
Lately, however, the increase in computing power has been achieved by the use of multi core CPUs (Central Processing Units) while raw clock frequencies have evolved at a slower pace.
Using graphics processing units to generate random numbers
The central idea is to view the Wasserstein distance d1 (µM , µ) from the empirical spectral measure of a random matrix M to a deterministic reference measure µ as the supremum of a stochastic process indexed by the unit ball of the (infinite-dimensional) space Lip(C) of real-valued Lipschitz functions on C.

The main parts of RTPIS are vehicle units in buses, station units at bus stops and a central data processing server.
Implementation of a Real Time Passenger Information System
When one (or more) of the four hit processing units detects a “large” hit, the unit books one of the central latency counters (in green).
Prototype ATLAS IBL Modules using the FE-I4A Front-End Readout Chip
Processor – the central processing unit today is a complex subsystem including the core processing element, two layers of cache, and external bus controllers.
Cluster Computing White Paper
The process involves many rods and cones in the eye being stimulated chemically by different frequencies of light, and the signals from different classes (color recognizing) of cells being combined within a central processing unit to form an image.
