How many address lines and Datalines are there in 8086?
8086 Microprocessor is an enhanced version of 8085Microprocessor that was designed by Intel in 1976. It is a 16-bit Microprocessor having 20 address lines and16 data lines that provides up to 1MB storage.
What is address line microprocessor?
An address line usually refers to a physical connection between a CPU/chipset and memory. They specify which address to access in the memory. So the task is to find out how many bits are required to pass the input number as an address.
How many address lines and Datalines are there in 8085?
16 address line
Which microprocessor has multiplexed data and address line?
Which microprocessor has multiplexed data and address lines? 8086/8088.
Which is part of the execution unit EU?
In computer engineering, an execution unit (E-unit or EU) is a part of the central processing unit (CPU) that performs the operations and calculations as instructed by the computer program.
What are segment and offset addresses?
A Segment Offset Address combines the starting address of a segment with an offset value. Segment and offset: Segments are special area defined in a program for containing the code, the data, and the stack.
What is meant by offset address?
In computer engineering and low-level programming (such as assembly language), an offset usually denotes the number of address locations added to a base address in order to get to a specific absolute address. In this context an offset is sometimes called a relative address.
How is logical address calculated?
we know that logical address spaces is = total no of bits required to represent total no of pages + bits required to map page offset . Hence total bits required = 3 (because total no of pages is 8 and to represent you need three bits) + 10 (page offset is 1024 so you need 10 bits) = 13 bits all total.
What is the purpose of logical address?
Logical address is used to reference to access the physical memory location. A logical address is generated so that a user program never directly access the physical memory and the process donot occupies memory which is acquired by another process thus corrupting that process.
What is the difference between logical and physical address?
The logical address is a virtual address and can be viewed by the user. The fundamental difference between logical and physical address is that logical address is generated by CPU during a program execution whereas, the physical address refers to a location in the memory unit.
