How are the address binding of instructions and data is carried to memory address?
Address binding of instructions and data to memory addresses can happen at three different stages: Compile time: If memory location known a priori, absolute code can be generated; must recompile code if starting location changes. Load time: Must generate relocateable code if memory location is not known at compile time. Execution time: Binding delayed until run time if the process can be moved during its execution from one memory segment to another. Need hardware support for address maps (e.g., base and limit registers).
What is compile-go loader?
compile and go loader is a type of loader function to have an assembler run in one part of the memory and places the assembled machine instructions,data as they are assembled,directly into their assigned memory location.
What does it mean to run a program?
In computer terminology, "running a program" means copying a sequence of instructions from storage into main memory and initiating the execution or interpretation of those instructions.
Does main memory provide the CPU with a working storage area for program instructions and data?
main memory provides buffers.buffers are the places where program execution takes place.but the CPU is provided with registers(memory units) there CPU can accomodate instructions and the data on which theses instructions are to be operated.from the main memory CPU fetches the instructions one by one and the instruction is processed in the CPU and then sends back the result to the main memory......i think so.thank u
Why is not possible to enforce memory protection at compile time?
This cannot be done at compile time because the memory allocated to a process is subject to change.
What is meant by flow of execution a program?
That means to load a computer program into a computer's memory, and have the computer carry out the instructions in the program.
What is address binding in operating systems?
A program, to be executed, must be brought to main memory. The instructions that use addresses in a program, must be bound to proper address space in main memory. Address binding is a scheme that performs this job. It can be thought as a mapping from one address space to another. There are bindings available as follows: Compile time binding Load time binding Execution time binding
What is dynamic mamory?
Dynamic memory refers to memory that is allocated and deallocated during program execution, as opposed to static memory which is allocated at compile time. In C and C++, dynamic memory allocation is done using functions like malloc() and free(), allowing for flexibility in managing memory resources at runtime. However, improper use of dynamic memory can lead to memory leaks or segmentation faults.
What is difference in static and dynamic storage allocation?
Static storage allocation is when a program dedicates an amount of memory for its use at the start of the program. Dynamic storage allocation is when a program only takes storage as it needs it.
What are the functions of cu and alu?
The ALU (Arithmetic Logic Unit) performs arithmetic and logical operations on data such as addition, subtraction, AND, OR, and NOT operations. The CU (Control Unit) manages the execution of instructions, fetching them from memory, decoding them, and coordinating the ALU, memory, and input/output devices to carry out the instructions.
How are programs copied into the CPU for it to read?
Programs are copied into the CPU for it to read through a process called loading. Loading involves transferring the program's instructions from storage, such as a hard drive or memory, into the CPU's memory for execution. This allows the CPU to access and execute the program's instructions in the correct sequence.
Why arm processor instructions are encoded?
ARM processor instructions are encoded to optimize performance and memory efficiency. By using a fixed-width or variable-width instruction format, ARM can reduce the size of the binary code, allowing for more efficient use of cache and memory. This encoding also facilitates easier decoding and execution of instructions by the processor, which can lead to faster execution times. Additionally, it allows for a rich set of instructions while maintaining a compact representation, contributing to the overall effectiveness of ARM architecture in various applications.
