The Elementary and Secondary School Emergency Relief Fund, also known as ESSER. [1] is a $190 billion program created by the U.S. federal government's economic stimulus response bills, the Coronavirus Aid, Relief, and Economic Security Act (), Consolidated Appropriations Act, 2021, the American Rescue Plan Act of 2021 (ARP Act), passed by the 116th and 117th U.S. Congress.
RISC OS Open Ltd. (also referred to as ROOL) [1] [2] is a limited company engaged in computer software and IT consulting. [3] It is managing the process of publishing the source code to RISC OS. [4] Company founders include staff who formerly worked for Pace, the company which acquired RISC OS after Acorn's demise. [5]
The first version of RISC OS was originally released in 1987 as Arthur 1.20. The next version, Arthur 2, became RISC OS 2 and was released in April 1989. RISC OS 3.00 was released with the A5000 in 1991, and contained many new features. By 1996, RISC OS had been shipped on over 500,000 systems. [15] An Acorn Archimedes A3020 computer running ...
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
RISC OS, the computer operating system developed by Acorn Computers for their ARM-based Acorn Archimedes range, was originally released in 1987 as Arthur 0.20, and soon followed by Arthur 0.30, and Arthur 1.20. The next version, Arthur 2, became RISC OS 2 and was completed and made available in April 1989.
HP PA-RISC 7300LC microprocessor HP 9000 C110 PA-RISC workstation booting Debian GNU/Linux. Precision Architecture RISC (PA-RISC) or Hewlett Packard Precision Architecture (HP/PA or simply HPPA), is a general purpose computer instruction set architecture (ISA) developed by Hewlett-Packard from the 1980s until the 2000s.
RISC-V [b] (pronounced "risk-five" [2]: 1 ) is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. . The project began in 2010 at the University of California, Berkeley, transferred to the RISC-V Foundation in 2015, and on to RISC-V International, a Swiss non-profit entity, in November 20
The PA-8000 is a four-way superscalar microprocessor that executes instructions out-of-order and speculatively. [1] [4] These features were not found in previous PA-RISC implementations, making the PA-8000 the first PA-RISC CPU to break the tradition of using simple microarchitectures and high-clock rate implementation to attain performance.
