Index Flex machine

The Flex Computer System was developed by Michael Foster and Ian Currie of Royal Signals and Radar Establishment (RSRE) in Malvern, England, during the late 1970s and 1980s.[1]

Abstract data type

In computer science, an abstract data type (ADT) is a mathematical model for data types, defined by its behavior (semantics) from the point of view of a user of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations.

See Flex machine and Abstract data type

ALGOL 68RS

ALGOL 68RS is the second ALGOL 68 compiler written by I. F. Currie and J. D. Morrison, at the Royal Signals and Radar Establishment (RSRE).

See Flex machine and ALGOL 68RS

Call stack

In computer science, a call stack is a stack data structure that stores information about the active subroutines of a computer program.

See Flex machine and Call stack

Capability-based addressing

In computer science, capability-based addressing is a scheme used by some computers to control access to memory as an efficient implementation of capability-based security. Flex machine and capability-based addressing are capability systems.

Garbage collection (computer science)

In computer science, garbage collection (GC) is a form of automatic memory management.

International Computers Limited

International Computers Limited (ICL) was a British computer hardware, computer software and computer services company that operated from 1968 until 2002.

Logica

Logica plc was a multinational IT and management consultancy company headquartered in London and later Reading, United Kingdom.

Malvern, Worcestershire

Malvern (locally also) is a spa town and civil parish in Worcestershire, England.

Microcode

In processor design, microcode serves as an intermediary layer situated between the central processing unit (CPU) hardware and the programmer-visible instruction set architecture of a computer, also known as its machine code.

See Flex machine and Microcode

PERQ

The PERQ, also referred to as the Three Rivers PERQ or ICL PERQ, is a pioneering workstation computer produced in the late 1970s through the early 1980s.

See Flex machine and PERQ

Proceedings of the Institution of Electrical Engineers

Proceedings of the Institution of Electrical Engineers was a series journals which published the proceedings of the Institution of Electrical Engineers.

PS-algol

PS-algol is an orthogonally persistent programming language.

See Flex machine and PS-algol

Remote procedure call

In distributed computing, a remote procedure call (RPC) is when a computer program causes a procedure (subroutine) to execute in a different address space (commonly on another computer on a shared computer network), which is written as if it were a normal (local) procedure call, without the programmer explicitly writing the details for the remote interaction.

See Flex machine and Remote procedure call

Royal Radar Establishment Automatic Computer

The Royal Radar Establishment Automatic Computer (RREAC) was an early solid-state computer in 1962.

See Flex machine and Royal Radar Establishment Automatic Computer

Royal Signals and Radar Establishment

The Royal Signals and Radar Establishment (RSRE) was a scientific research establishment within the Ministry of Defence (MoD) of the United Kingdom.

Ten15

Ten15 is an algebraically specified abstract machine. Flex machine and Ten15 are science and technology in Worcestershire.

See Flex machine and Ten15

Weak reference

In computer programming, a weak reference is a reference that does not protect the referenced object from collection by a garbage collector, unlike a strong reference.
