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.
DMA Hardware (8237 DMAC) : 1)Processor contain HOLD/HOLD Acknowledge lines to interact with 8237 o DMAC can achieve control of ISA bus by asserting HOLD o P
Write a program that performs the addition, subtraction, multiplications, division of the given operands. Perform BCD operation for addition and subtraction.
This is a short program to practice assembly language loops and if/else statements. You will use various jump commands and the cmp instruction. The program will generate a random
CMP: Compare: - This instruction compares the source operand, which can be a register or memory location an immediate data with a destination operand that might be a register or a
take an integer and its base and the base in which you want to convert the number from user and perform conversion.
Modes of 8254 : Mode 0 (Interrupt on Terminal Count)-GATE which value is 1 enables counting and GATE which value is 0 disables counting, and GATE put not effect on
