Types of Bus on Microprocessor
Length of Address Bus of 8085 microprocessor is 16 Bit (That is, Four Hexadecimal Digits), ranging from 0000 H to FFFF H, (H denotes Hexadecimal). The microprocessor 8085 can transfer maximum 16 bit address which means it can address 65, 536 different memory location.
The Length of the address bus determines the amount of memory a system can address.Such as a system with a 32-bit address bus can address 2^32 memory locations.If each memory location holds one byte, the addressable memory space is 4 GB.However, the actual amount of memory that can be accessed is usually much less than this theoretical limit due to chipset and motherboard limitations.
Data bus -
It is a group of conducting wires which carries Data only.Data bus is bidirectional because data flow in both directions, from microprocessor to memory or Input/Output devices and from memory or Input/Output devices to microprocessor.
Length of Data Bus of 8085 microprocessor is 8 Bit (That is, two Hexadecimal Digits), ranging from 00 H to FF H. (H denotes Hexadecimal).
When it is write operation, the processor will put the data (to be written) on the data bus, when it is read operation, the memory controller will get the data from specific memory block and put it into the data bus.
