Presence in Modern Systems
Many modern processors now contain multiple processing cores and have different buses for instructions and data (for example the Harvard architecture and MIMD). Furthermore, many modern CPUs support out-of-order execution and other advanced optimization heuristics. Thus these systems do not implement a von Neumann architecture at the hardware level. However, they retain some of its obvious features such as random access memory (RAM).
Many widely used programming languages such as C++ and Java have ceased to be strictly von Neumann by adding support for parallel processing, in the form of threads. However, most of the categorically non-von Neumann languages are also functional languages and have not achieved widespread use.

Famous quotes containing the words presence in, presence, modern and/or systems:
“I dont think there is anything on earth more wonderful than those wistful incomplete friendships one makes now and then in an hour’s talk. You never see the people again, but the lingering sense of their presence in the world is like the glow of an unseen city at night—makes you feel the teemingness of it all.”
—John Dos Passos (1896–1970)
“The City of New York is like an enormous citadel, a modern Carcassonne. Walking between the magnificent skyscrapers one feels the presence on the fringe of a howling, raging mob, a mob with empty bellies, a mob unshaven and in rags.”
—Henry Miller (1891–1980)
“An ... important antidote to American democracy is American gerontocracy. The positions of eminence and authority in Congress are allotted in accordance with length of service, regardless of quality. Superficial observers have long criticized the United States for making a fetish of youth. This is unfair. Uniquely among modern organs of public and private administration, its national legislature rewards senility.”
—John Kenneth Galbraith (b. 1908)
“The geometry of landscape and situation seems to create its own systems of time, the sense of a dynamic element which is cinematising the events of the canvas, translating a posture or ceremony into dynamic terms. The greatest movie of the 20th century is the Mona Lisa, just as the greatest novel is Gray’s Anatomy.”
—J.G. (James Graham)
