What is Run-time Environment

Chapter 17
Handbook of Research on Industrial Informatics and Manufacturing Intelligence: Innovations and Solutions
Stands for “Runtime Environment.” As soon as a software program is executed, it is in a runtime state. In this state, the program can send instructions to the computer’s processor and access the computer’s memory (RAM) and other system resources. When software developers write programs, they need to test them in the runtime environment.

Abstract
This research deals with reconfigurable uniprocessor embedded real-time systems to be implemented by different OS tasks that should be independent, synchronous, and periodic, and that should meet functional and temporal properties described in user requirements. The authors define two forms of automatic reconfigurations assumed to be applied at run-time: addition-removal of tasks or just modifications of their temporal parameters; WCET and/or periods. The authors define a new semantic of reconfigurations where a crucial criterion to consider is the automatic improvement of the system’s feasibility at run-time.
