What was the PDP-11 used for?
Use. The PDP-11 family of computers was used for many purposes. It was used as a standard minicomputer for general-purpose computing, such as timesharing, scientific, educational, medical, or business computing.
How much memory did a PDP-11 have?
Later-model PDP-11 processors included memory management to support virtual addressing. The physical address space was extended to 18 or 22 bits, hence allowing up to 256 KB or 4 MB of RAM.
What is the full form of PDP-11?
PDP-11 (Programmed Data Processor-11) is one of the most famous computers in computing history, one of a series manufactured by Digital Equipment Corporation ( DEC ) from the early 1960s through the mid-1990s.
Who created the PDP-11?
Digital Equipment Corporation
PDP-11/Manufacturers
Who invented PDP-11 computer?
PDP-11/Inventors
It seems however that the designed by de Castro PDP-X has little relationship to DEC’s eventual 16-bit architecture, the PDP-11. Gordon Bell, the vice president of research in DEC, was involved with recommending what became the PDP-11, while the actual design was made by Harold McFarland.
How many registers should the PDP 10 have?
There are 16 general-purpose, 36-bit registers. The right half of these registers (other than register 0) may be used for indexing. A few instructions operate on pairs of registers.
What is the full form of PDP 8?
Programmed Data Processor (PDP), referred to by some customers, media and authors as “Programmable Data Processor,” is a term used by the Digital Equipment Corporation from 1957 to 1990 for several lines of minicomputers.
Who invented PDP 11 computer?
Is a brain of computer?
Central Processing Unit (CPU) The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it.
What kind of instruction set is PDP 11?
The PDP-11 architecture is a CISC instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). It is implemented by central processing units (CPUs) and microprocessors used in PDP-11 minicomputers. It was in wide use during the 1970s, but was eventually overshadowed by the more powerful VAX-11 architecture in the 1980s.
When did the PDP-11 architecture come into use?
It is implemented by central processing units (CPUs) and microprocessors used in PDP-11 minicomputers. It was in wide use during the 1970s, but was eventually overshadowed by the more powerful VAX-11 architecture in the 1980s. Sixteen-bit words are stored little-endian (with least significant bytes first).
Who is the developer of the PDP-11 Isa?
The PDP-11 architecture is an instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). It is implemented by central processing units (CPUs) and microprocessors used in PDP-11 minicomputers.
It is one of a series of papers by Gordon Bell, and various co-authors, spanning the design, growth, and eventual replacement of the companies iconic line of PDP-11 mini computers.
