What happened to DEC Alpha?
After several attempts to enter the workstation and file server market, the DEC Alpha product line began to make successful inroads in the mid-1990s, but was too late to save the company….Digital Equipment Corporation.

What is Alpha operating system?
Alpha of OS (Alfa OS) – the operating system for the personal computer. OS is created on Linux- a core and is compatible to Debian GNU/Linux. The alpha of OS supports more than 150 thousand applications created including for Windows.
What is Alpha architecture?
The Alpha architecture is the first 64-bit load/store RISC (as opposed to CISC) architecture designed to enhance computer performance by improving clock speeding, multiple instruction issuing and multiple processors management.
How many instructions per clock cycle can Digital Alpha 21164 can issue?
four instructions per clock
Description. The Alpha 21164 is a four-issue superscalar microprocessor capable of issuing a maximum of four instructions per clock cycle to four execution units: two integer and two floating-point.
Why did December ultimately fail?
DEC identified a demand for more affordable and high-performing computing systems that could be used in scientific research and other technological settings. Most argue that it was a failure of the company’s leadership to adapt to the changing direction that computing began to take in the late 1980s.
Does Alpha Support Zero register?
Explicit load and store operations are required to move data between memory and registers. Conditional branches can only test the relation between a register and the value zero. Alpha supports integer operations for both 4-byte and 8-byte integers.
Does alpha Support Zero register?
What is Alpha platform of Tata Motors?
Tata says cars built on the ALFA platform will stretch between 3.7-4.3m in length, the wheelbase is stretchable to a not-so-insignificant 2,450mm, the front and rear track can be altered, and should engineers and designers choose, the cars, SUVs, and MPVs could be as wide as 1,800mm too.
What is the full from of RISC?
RISC, or Reduced Instruction Set Computer. is a type of microprocessor architecture that utilizes a small, highly-optimized set of instructions, rather than a more specialized set of instructions often found in other types of architectures.
What is Alpha microprocessor?
Alpha was a microprocessor from Digital Equipment Corporation which was based on 64-bit reduced instruction set computing (RISC). It was designed to replace DEC’s 32-bit VAX complex instruction set. The DEC Alpha microprocessors were used in a variety of Digital Equipment Corporation’s servers and workstations.
Who are beta males?
Beta males are the ‘lieutenants’ of the socio sexual hierarchy. They’re fiercely loyal to their alphas. In exchange for this loyalty, they enjoy many of the benefits of high status and position. Beta males are crucial to a stable hierarchy, and enforce the alpha’s rules to maintain order and structure.
When did hp stop supporting the AlphaServer system?
The availability of upgrades and options was discontinued on 25 April 2008, approximately one year after the systems were discontinued. Support for the most recent AlphaServer systems, the DS15A, DS25, ES45, ES47, ES80 and GS1280 is being provided by HP Services as of 2008.
What was the purpose of the DEC Alpha processor?
Alpha was designed to replace 32-bit VAX complex instruction set computer (CISC) as well as be a highly competitive RISC processor for Unix workstations and similar markets. Alpha is implemented in a series of microprocessors originally developed and fabricated by DEC.
When did the Compaq alpha server come out?
AlphaServer was the name given to a series of server computers, produced from 1994 onwards by Digital Equipment Corporation, and later by Compaq and HP.
Are there any condition codes for DEC Alpha?
The Alpha does not have condition codes for integer instructions to remove a potential bottleneck at the condition status register. Instructions resulting in an overflow, such as adding two numbers whose result does not fit in 64 bits, write the 32 or 64 least significant bits to the destination register.
