What is use of offset address in 8086 mp?
Offset address is also known as displacement.By adding this offset value to a base address,address of a specific locaction in memory can be accessed
How do you obtain offset address?
To obtain an offset address, you typically start with the base address of a memory segment and add the desired offset value to it. In programming, this can be done using pointer arithmetic. For example, in C or C++, if you have a pointer pointing to a base address, you can obtain the offset address by adding an integer value to that pointer. The resulting address points to a specific location within the memory segment relative to the base address.

How do you calculate instruction address and data address give example?
To calculate an instruction address and a data address, you typically use the base address and an offset. For example, if the base address of a program is 0x1000 and the instruction is located at an offset of 0x0040, the instruction address would be calculated as 0x1000 + 0x0040 = 0x1040. Similarly, if a data item is stored at an offset of 0x0020 from the same base address, the data address would be 0x1000 + 0x0020 = 0x1020.
What is indexed addressing mode?
When stored in contiguous blocks, data usually has a base address. Accessing any data from the block requires an offset to the base address which is achieved through an index. The adding of an offset to the base address is called indexed addressing.
How do you calculate effective address?
To calculate the effective address in a computer system, you typically follow a formula that incorporates the base address, index, and offset. The effective address is determined by adding the base address to the product of the index register and the scale factor, along with any immediate offset. The general formula can be expressed as: Effective Address = Base Address + (Index × Scale) + Offset. This calculation is commonly used in assembly language and memory addressing modes.
How can one calculate the physical address from a given logical address?
To calculate the physical address from a logical address, you can use the base address and offset. Add the base address to the offset to get the physical address. This process is commonly used in computer systems to translate logical addresses to physical addresses for memory access.
Write a program using the following figure that determines and displays the physical addresses and the accessible physical addresses for each of the above logical addresses?
The Physical address can be calculated asPhysical address = Base address + Offset.So take Base,Offsets,Lengths in to different arrays and check whether offset is less than length , if it is then the physical address would be base+ Offset , if not then that is a segment error.
What is offset in microprocessors?
Refers to a value added to a base address to produce a second address. For example, if B represents address 100, then the expression,B+5would signify the address 105. The 5 in the expression is the offset.Specifying addresses using an offset is called relative addressing because the resulting address is relative to some other point. Another word for offset is displacement.Ajesh John
What is offset address?
An offset address is a relative address rather than an absolute address. You use offsets to refer to memory relative to an absolute address. For instance, array indices are implemented using offsets from the start address of the array, such that element 0 is at offset 0 and element 5 is at offset 5.
How the CPU will give the logical segment base addresses and offset addresses?
The CPU uses the segment registers to provide the base addresses for logical segments, which correspond to parts of a program's memory, such as code, data, and stack segments. When an application references a memory address, it specifies a segment selector (the logical segment) and an offset within that segment. The CPU combines the base address from the segment register with the offset to calculate the physical address in memory. This segmentation allows for organized memory management and protection between different segments of a program.
