What it the size bit address for 8085 and 8086?
128Kb
Size of 8086 address bus?
The 8086/8088 has an internal 20-bit address bus and 16-bit data bus. Externally, the address bus is 20-bits, and the data bus is 16-bits for the 8086 and 8-bits for the 8088.The data bus in the 8086 is 16 bits in size, while the address bus is 20.
What is the size of address bus in 8086?
The address bus in the 8085 is 16 bits wide.
Maximum RAM capacity of 8086 processor?
The 8086/8088 can address a maximum of 220, or 1,048,576, or 1 MB of memory.
What is the max ram for a 20 wire CPU address bus?
220 or 1,048,576 locations, otherwise known as 1 meg. If its an 8 bit bus, we are talking about 1 megabyte. That happens to be the size of the address bus of the original 8086/8088 microprocessor.
What is physical address in 8086 microprocessor?
Physical address in the 8086/8088 is {Selected Segment Register} * 16 + {Effective Offset Address}. It is a 20-bit address .
Does 8086 has memory?
8086 does not have RAM or ROM inside it. However, it has internal registers for storing intermediate and final results.
How many address lines are required to access 1MB RAM using microprocessor 8086?
The 8086/8088 microprocessor has a 20 bit address bus, so the number of memory locations it can address is 220 or 1,048,576.
Why 4 bit address bus is grounded?
The data bus in the 8086 is 16 bits in size, while the address bus is 20 (16bits would only address 64KB of memory, an extra 4 bits allows to address the total of 1MB, this is done trough segmentation of the memory). To form a multiplexed of data bus and address bus, four bits of 8086 address bus are grounded.
How many memory address does this number of address lines allow the 8086 to access directly?
The 8086/8088 has 20 address lines. It can access 220, or 1MB, or 1,048,576 bytes of memory.
What is the size of the interrupt vector table in the 8086-8088 microprocessor?
There are 256 different interrupt vectors in the 8086/8088. Each vector is a far CS:IP address, which is four bytes. That makes the interrupt vector table 1,024 bytes.
What is the highest memory address?
The highest memory address in the 8086/8088 is FFFFFH.
