What is Relocation data?
Relocation is the process of assigning load addresses for position-dependent code and data of a program and adjusting the code and data to reflect the assigned addresses.
What is a relocation register?
Relocation and limit registers are used to protect user processes from each other. Relocation register contains value of the smallest part of the physical address. Limit register contains range of logical addresses, each logical address must be less than the limit register.
What is relocation loader?
A relocating loader is capable of loading a program to begin anywhere in memory: The addresses produced by the compiler run from 0 to L–1. After the program has been loaded, the addresses must run from N to N +L–1. Therefore, the relocating loader adjusts, or relocates, each address in the program.
What is the difference between static and dynamic relocation?
Static Relocation - Program must be relocated before or during loading of process into memory. Program must always be loaded into same address space in memory, or relocator must be run again. Dynamic Relocation - Process can be freely moved around in memory.
What is relocation problem in memory management?
Relocation problem. Having multiple partitions presents a problem: This means that references to particular memory addresses within the program won't be the same every time the program runs. For example, the program might call a particular function that begins 1024 bytes into the program.
What is deadlock explain?
A deadlock is a situation in which two computer programs sharing the same resource are effectively preventing each other from accessing the resource, resulting in both programs ceasing to function. The earliest computer operating systems ran only one program at a time.
What is relocatable address?
An address expression that has a fixed value, independent of run-time considerations such as where the program is located in memory, is called an absolute address expression. An address expression with a value that depends on run-time considerations is called a relocatable address expression.
What is absolute and relocatable program?
Basically, "absolute" mode means that the code and RAM variables will be placed exactly where you tell the assembler it will be, while "relocatable" means the assembler builds code chunks and specifies RAM needs that can be placed wherever the linker finds room for them.
What is assembler directive?
Assembler directives supply data to the program and control the assembly process. Assembler directives enable you to do the following: Assemble code and data into specified sections. Reserve space in memory for uninitialized variables. Control the appearance of listings.
