  Aim:  Write a program using 8085 & verify for:              1. Subtraction of Two 8-Bit Numbers.  (Display Of Borrow)               2. Addition of Two 16-Bit Numbers.  (Display Of Borrow)

Aim: Write a program using 8085 & verify for:               1. Addition of Two 8-Bit Numbers.              2. Addition of Two 16-Bit Numbers (With Carry)  

Aim:  To implement various 4-bit arithmetic Micro-operations           using arithmetic unit.   Theory Arithmetic micro operation of the form L:   R A  ( R A + R B ) refers to two data items contained in R A and R B input to a parallel adder with the result being stored back in R A (Fig.). Loading      of the result in R A is subject to the availability   of the control   signal designated as L   (that   is   load control of R A ) . Note that adder being a combinational logic, the adder output is available after a delay of the associated combinational circuit. Input to adder may be also controlled by providing AND word gates on the data paths from R A and R B to the adder under the control signal C (Fig.). the control signals `C' and 2's complement are at logic `0' for add operation.   The subtract micro operation L:   R A  ( R A - R B ) in 2's comp...
