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 ...
t. e. In computer science, an instruction set architecture ( ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.
As a RISC architecture, the RISC-V ISA is a load–store architecture.Its floating-point instructions use IEEE 754 floating-point. Notable features of the RISC-V ISA include: instruction bit field locations chosen to simplify the use of multiplexers in a CPU, [2]: 17 a design that is architecturally neutral, [dubious – discuss] and a fixed location for the sign bit of immediate values to ...
The United States Army Intelligence Support Activity (USAISA), frequently shortened to Intelligence Support Activity (ISA), also known at various times as Mission Support Activity (MSA), Office of Military Support (OMS), Field Operations Group (FOG), Studies and Analysis Activity (SAA), Tactical Concept Activity, Tactical Support Team, and Tactical Coordination Detachment, [1] and also ...
The International Society of Automation ( ISA ), formerly known as The Instrumentation, Systems, and Automation Society, [ 3] is a non-profit technical society for engineers, technicians, businesspeople, educators and students, who work, study or are interested in automation and pursuits related to it, such as instrumentation.
e. International Standards on Auditing ( ISA) are professional standards for the auditing of financial information. These standards are issued by the International Auditing and Assurance Standards Board (IAASB). According to Olung M (CAO - L), ISA guides the auditor to add value to the assignment hence building confidence of investors.
International Standard Atmosphere. The International Standard Atmosphere ( ISA) is a static atmospheric model of how the pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes or elevations. It has been established to provide a common reference for temperature and pressure and consists of ...
Income share agreement. An income share agreement (or ISA) is a financial structure in which an individual or organization provides something of value (often a fixed amount of money) to a recipient who, in exchange, agrees to pay back a percentage of their income for a fixed number of years. ISAs have gained prominence as an alternative to the ...
