What is the addressing mode of the instruction PCHL in 8085 microprocessor?
It is register addressing mode, as it moves the content of HL to PC which is data and not address.
A microprocessor with 12 address lines is capable of addressing?
A microprocessor with 12 address lines is capable of addressing 4096 locations in memory. The Intel 4004 and the DEC PDP-8 are examples of processors with 12 address lines.
What are addressing mode in microprocessor?
Addressing modes of 8051 are 1.Immediate Addressing Mode 2.Register Addressing Mode 3.Register Indirect Addressing Mode 4.Direct Addressing Mode 5.Implied Addressing Mode and 6.Relative Addressing Mode
Why is the jump instruction jmp of 8085 microprocessor given the immediate addressing mode?
because the operand is available in the instruction itself
Which microprocessor part their tempararily data stored?
Usually memory banks made up of SRAMs or DRAMs or EPROMs consist of the storage area provided on a microprocessor. For understanding how the address space of a 20 bit address line microprocessor is organised, read about address decoding for even and odd memory addressing through SRAMs and EPROMs.
Difference between direct addressing mode and indirect addressing modein8085 microprocessor?
When a microprocessor wants to store a byte of information in memory, or retrieve a byte of information from memory, it needs to refer to the address of the byte in the instruction. When direct addressing is used then the microprocessor instruction refers explicitly to the address that is to be used. When indirect addressing is used then the microprocessor instruction refers to a third object that refers to the address that is to be used. So, for example: Direct addressing: (*) Store the data at address 0x3C6E (*) Deliver the letter to house 12 on the street. Indirect addressing: (*) Store the data at whatever address is in register AX. (*) Deliver the letter to whichever house the occupant of house 7 tells you. So, in indirect addressing, the microprocessor instruction refers to some other "third-party" location (a register or another memory location) to find-out what the ultimate address to be used should be. The instruction does not contain all of the information needed to store the byte (or deliver the letter) but it does say where the missing information can be found. In direct addressing, the instruction contains all of the information needed to store the byte (or deliver the letter). This is basically true for all microprocessors but different microprocessors allow different forms of indirect addressing. For example, some use memory indirect addressing (the third party is another memory location), and some use register indirect addressing (the third party is a register).
What do you mean single and double handshaking of microprocessor 8086?
They are the ways of transmitting parallel data to the microprocessor. In single handshake, a peripheral device first sends a "Strobe signal" to the microprocessor to indicate that it is ready to send data. The microprocessor , upon detecting the strobe signal, opens up its input port and receives the data. After receiving data, it sends an "Acknowledge signal" to the peripheral to indicate that transmission has been completed.A transmission session has been completed. In double handshake, first the peripheral device sends a strobe signal, the microprocessor, sends the acknowledge signal to indicate that it is ready to receive data. After which data is received.After sending data, the peripheral sends a strobe signal to indicate data transmission completion, due to which, the microprocessor drops its acknowledge signal and a session has been completed. The only difference in the two is that, in double handshake, the peripheral is informed about the microprocessor's readiness to receive data. This is doesn't happen in single handshake. So the name follows "double handshake", literally meaning "double confirmation".
How many pins are present in 8085 and 8086 microprocessor?
There are 256 ports available in the 8085 microprocessor. The IN and OUT instructions have an 8-bit port number, and that is where the 256 comes from.In order to use ports, the hardware addressing system must decode IO/M-. Some implementations don't do this, so they map IO addresses to memory addresses. In that case, you could say there are 65536 possible IO addresses, but that is not the same as ports, because ports are specific to the IN and OUT instructions.The other "problem" with IN and OUT is that you cannot specify the address in a register, while you can do so with indirect memory addressing.

What is the plural of microprocessor?
The plural of microprocessor is microprocessors.
Microprocessor is single chip processor or multi chip?
Microprocessor is a single chip processor.
What is the microprocessor of Windows 7?
The microprocessor is a piece of hardware, not software. Windows 7 doesn't supply a microprocessor.
