16 Οκτ 2024 · Parts of Resident Monitor. Control Language Interpreter: The first part of the Resident monitor is control language interpreter which is used to read and carry out the instruction from one level to the next level.
7 Μαΐ 2023 · The Resident Monitors are divided into 3 parts: 1. Control Language Interpreter. The job of the Control Language Interpreter is to read and carry out the instructions line by line to the next level. 2. Loader. The Loader is the main part of the Resident Monitor.
RESIDENT MONITOR: Primitive Operating System. Usually in low memory where interrupt vectors are placed. Must check each memory reference against fence ( fixed or variable ) in hardware or register. If user generated address < fence, then illegal. User program starts at fence -> fixed for duration of execution. Then user code has fence address ...
In a uniprogramming system, main memory is divided into two parts: one part for the operating system (resident monitor, kernel) and other part for the program currently being executed. In a multiprogramming system, the “user” part of memory must be further subdivided to accommodate multiple processes.
Typical functions of a resident monitor include examining and editing ram and/or ROM (including flash EEPROM) and sometimes special function registers, the ability to jump into code at a specified address, the ability to call code at a given address, the ability to fill an address range with a constant such as 0x00, and several others.
Resident Monitor In this type of system, there are 2 sections of memory: one for the monitor, the other for the user. The monitor is usually put wherever more convenient; as the interrupt vectors are usually in low memory, so is the monitor.
Parts of resident monitor – Control card interpreter – responsible for reading and carrying out instructions on the cards. – Loader – loads systems programs and applications programs into memory. – Device drivers – know special characteristics and properties for each of the system’s I/O devices.
