Digital Logic and Microprocessors

It holds the location of current stack frame.

The output is high only when any one of the inputs were high and output is low if both inputs are at the same logic.

It requires two Ex-OR gate for sum generation and two AND gates, one Ex-OR gate and one OR gate for the carry generation.

Here, the output is high only when all inputs are high at the same time

It has a typically fast update period but a disproportionately slow step recovery.

This logic circuit is to detect the presence of a specified combination of bits on its inputs and to indicate that presence by a specified output level.

This flag is set if a result is out of range in 8086 processor.

The output is high any time at least one of its inputs is high.

This logic circuit adds two 4-bit BCD code groups, using straight binary addition.

This may be useful in I/O operations with serial devices, or anyplace that error checking is to be done in 8085 processor.

Here, each operand datum occupies one word, with its low order part being in the first byte and its high order part being in the second byte in 8086 processor.

Here, the output is ON only when both the inputs are ON or OFF.

It takes data from the one input line and distributes it to output lines.

Here, the counter will receive a low signal on the active low LOAD input, causing it to reset to 00000000 on the next clock pulse.

Here, the register monitors the comprator's output to see if the binary count is less than or greater than the analog signal input, adjusting the bit values accordingly.
