Program : Write a program to perform a one byte BCD addition.
Solution :
It is consider that the operands are in BCD form, but the CPU considers it as hexadecimal and accordingly performs addition operation. Assume the following example for addition. Carry is set to be 0.
Actual result after addition considering hex operand
In this program, the DAA instruction is used after ADD. In similar manner, DAS can be used after instruction SUB.
Pin functions for the minimum mode operation of 8086 are following: 1) M/I/O -Memory/IO: This is a status line logically equivalent to S2 in maximum mode. When it is low, it
ROR : Rotate Right without Carry: This instruction rotates the contents of destination operand to the bit-wise right either by one or by the count specified in register CL, exclud
Execution Unit (EU) and Bus Interface Unit (BIU) : 8086 consist of two processors called EU and BIU. Two Processors can work parallel. This improves speed of execution. BIU fi
A good starting point for your program is the toupper.asm program shown in class. It already queries the user for input and sets up a loop that looks at each character of the input
