Example The following example divides 8 with 2. The product is in AX. The dividend 8 is stored in the bit AX register and the divisor 2 is stored in the 8-bit BL register. In case of multiplication, overflow does not occur because double-length registers are used to keep the product.

This means that you need to make sure there are at least three instructions between an instruction that uses the Y register as a destination and an instruction that uses the value stored in the Y register.

The second format copies the contents of an integer register to the Y register. However, in case of division, overflow may occur. After division, the quotient goes to the AL register and the remainder goes to the AH register.

The integer multiplication operations smulcc and umulcc always clear the V overflow and C carry bits of the condition code register. Like the addition and subtraction operations, the multiplication and division operations have two assembly language formats: The high-order leftmost portion gets stored in DX and the lower-order rightmost portion gets stored in AX.

The third instruction format stores a small integer constant into the Y register. As with the other arithmetic operation add and subthere are versions of the multiplication and division operations that update the condition code bits and other multiplication and division operations that do not alter the condition code bits.

In many other cases you will need to examine or set the contents of the Y register.

The processor generates an interrupt if overflow occurs. How is the Y register used in the integer multiplication operations? These operations had to be performed using more primitive operations. Both instructions affect the Carry and Overflow flag. Integer multiplication The integer division operations divide a bit value into a bit value and produce a bit result.

The unsigned operations interpret their source operands as unsigned integers and produce unsigned integer results. In addition, these operations update the N negative and Z zero bits of the condition code register.

In addition, the division operations update the N, Z, and V bits in the condition code register based on the value of the bit result.

The high-order 16 bits are in DX and the low-order 16 bits are in AX. The resultant product is a doubleword, which will need two registers.

Like the multiplication operations, the division operations sdivcc and udivcc also clear the C bit in the condition code register. The product generated is stored in the EDX: The Y register provides the most significant 32 bits of the bit dividend.

Both the instructions can work with 8-bit, bit or bit operands. The multiplication sets the Y register and the division uses the value set by the multiplication. The operation affects all six status flags. How is the Y register used in the integer division operations?

One of the source values provides the least significant 32 bits, while the other provides the 32 bit divisor. The mov operation applied to the Y register. You can also use the mov operation to set the contents of the Y register.

You can use the mov operation to examine and set the contents of the Y register. After division, the bit quotient goes to the AX register and the bit remainder goes to the DX register.

High-order 8 bits of the product is stored in AH and the low-order 8 bits are stored in AL. Although the multiplication operations produce a bit result, updates to the N and Z flags are only based on the least significant 32 bits of the result.

In writing this code you should assume that a, b, and c are signed integer values and that all results can be represented in 32 bits. Again, you should assume that a, b, and c are signed integers and that all results can be represented in 32 bits.matrix multiplication assembly language, Search on matrix multiplication assembly language write cash register using assembly language: Dec assembly language: Nov assembly language Assembly Language problem, could anyone help me please?
