What is the size of address bus in 8086?
The address bus in the 8085 is 16 bits wide.
What is memory address register of Intel 8085?
8 bits
How do you address 1GB memory with 8085 or 8086?
You cannot address 1GB memory with the 8085 or the 8086/8088 without some kind of external demultiplexor that is software controlled. The address bus on the 8085 is 16 bits, giving addressibility of 64KB; while the address bus on the 8086/8088 is 20 bits, giving addressibility of 1MB. To address 1GB, you need a 30 bit address bus.
Why stack pointer is of 16 bit in 8085?
The stack pointer is 16 bits in size on the 8085 because that is how Intel designed it. The address bus is also 16 bits, so it made sense for the program and stack to be located anywhere in that address space.
Why memory capacity of 8085 mp is 64 KB?
The memory capacity of the 8085 microprocessor is 64 kb because the address bus is 16 bits, and you can address 216, or 64kb, with a 16 bit address bus.
How many bits in 8085 microprocessor?
The 8085 is an 8-bit microprocessor. Even though there are some 16-bit registers (BC, DE, HL, SP, PC), with some 16-bit operations that can be performed on them, and a 16-bit address bus, the accumulator (A), the arithmetic logic unit (ALU), and the data bus are 8-bits in size, making the 8085 an 8-bit computer.
According to word size how many instruction in 8085?
The 8085 is an 8 bit processor, so its word length is 8 bits.
How many memory address can by address by 8085?
64 kb
How the width of address bus in 8085 decided?
The width of the address bus on the 8085 was decided based on a compromise between functionality, cost, and complexity. Intel decide to use 16 bits, as that was in keeping with common design at that time, and also because the 8085 was actually an enhanced version of the 8080.
What is the data size in Intel 8085?
The data size in the 8085 is 8 bits.
What is the address space in a system with 16-bit addresses?
It depends on the size of the address bus, which is often different than the size of the data bus.If the address bus were 8 bits, then you could address 256 locations.If the address bus were 16 bits, such as in the 8085, then you could address 65,536 locations.If the address bus were 20 bits, such as in the 8086/8088, then you can address 1,048,576 locations.
How many bits are contained in the A register of a 8085 CPU?
8085 is a 8 bit microprocessor and so A register which is also known as accumulator is also 8 bit.
