Processors
Processor electronics standards are published by IEC and ISO. This list covers a variety of computation topics such as terminology of microprocessors and numerical control in computers. Processors must be able to perform operations such as floating point arithmetic, numerical control, and post-processing.
ISO/IEC 60559:2020
Information technology - Microprocessor Systems - Floating-Point arithmetic
This standard specifies interchange and arithmetic formats and methods for binary and decimal floating-point arithmetic in computer programming environments. This standard specifies exception conditions and their default handling. An implementation of a floating-point system conforming to this standard may be realized entirely in software, entirely in hardware, or in any combination of software and hardware. For operations specified in the normative part of this standard, numerical results and exceptions are uniquely determined by the values of the input data, sequence of operations, and destination formats, all under user control.
ISO 4343:2000
Industrial automation systems -- Numerical control of machines -- NC processor output -- Post processor commands
This International Standard defines the elements of a set of post processor statements to be used in numerical control software. These statements are encoded on 2 000 class and 20 000 class CLDATA records or their equivalent.
Each processor using one of the ISO numerical control programming languages shall be capable of producing post processor command type CLDATA records as defined in this International Standard.
Each post processor shall be capable of using the post processor command type CLDATA records defined in this international Standard as input.
This International Standard does not prescribe
- the mechanism by which the statements are processed;
- the medium on which the input language statements are recorded;
- the medium and format of output machine control data;
- the order of statements within a part program.
