Hardware Questions

8085 is a one address microprocessor. In 8085 interrupts  are classified by software and hardware interrupts.

RST 4.5 is called as TRAP.

A SIPO and AND gate circuit can detect this sequence.The output of SIPO is connected to a four input AND gate ,the third SIPO output should be connected through a NOT gate.When the 1101 sequence is loaded in to the SIPO the AND output goes HIGH otherwise keeps LOW.

 Main Boot Record is located in sector 0, track 0, head 0, cylinder 0 of the primary active partition.

Microprocessor is a program-controlled device, which fetches the instructions from memory. decodes and executes the instructions. Most Micro Processors are single-chip devices.

1. Address lines to refer to the address of a block

2. Data lines for data transfer

3. IC chips

4. Processing data

RST0, RST1, RST2, RST3, RST4, RST5, RST6, RST7.

Microprocessor contain ROM chip beacause it contain instructions to execute data. It contain the monitor program which not only include execution instruction but also interfacing program
