What are different types of registers in a basic computer?
computer has different registers each of which has different functions. ax - accumulator register bx - base register cx - counter register computer has different registers each of which has different functions. ax - accumulator register bx - base register cx - counter register
WHAT IS BX in general purpose register?
EBX --> Extended Base Register. Extended means, it stores more data than 'Base Register' OR BX. BX is a 16 bit register, where EBX is 32 bit. Base register stores the base address, ie the starting address with respect to a segment.
What is the MOV instruction of microcontroller PIC16F877A?
•The mov instruction carries out assignment in 8086 assembly language. •It which allows us place a number in a register or in a memory location (a variable) i.e. it assigns a value to a register or variable. Example: Store the ASCII code for the letter A in register bx.•A has ASCII code 65D (01000001B, 41H) •The following mov instruction carries out the task:•mov bx, 65d•We could also write it as:•mov bx, 41h•or mov bx, 01000001b•or mov bx, 'A'
What isBX register?
The BX register is a general purpose register. It is a 16 bit register that represents the contatenation of the two 8 bit registers BH (B High) and BL (B Low)
What is the possible machine instruction equivalent to mov bx 24?
The instruction mov bx, 24 in assembly language moves the immediate value 24 into the BX register. The possible machine instruction equivalent for this operation, assuming a 16-bit x86 architecture, would typically involve an opcode for moving an immediate value into a register, such as B8 18 00, where B8 is the opcode for moving an immediate value into the AX register, and 18 00 represents the little-endian format of the number 24. However, for the BX register specifically, the opcode would be BB, resulting in a machine code like BB 18 00.
How do you write a code to complement the corresponding bit in bxif AX contains 6complement the 6th bit of BX in assembly?
To complement the 6th bit of the BX register in assembly language, you can use the XOR instruction. First, create a mask that has the 6th bit set (binary 00100000, which is 0x20 in hexadecimal). Then, XOR the BX register with this mask to toggle the 6th bit. Here's an example in x86 assembly: mov ax, <value> ; Load AX with some value xor bx, 0x20 ; Complement the 6th bit of BX This will flip the 6th bit of BX without affecting the other bits.
What is the function of bx register?
The BX register in x86 assembly language serves as a general-purpose register primarily used for storing data and addresses. It can act as a base pointer for memory addressing in certain addressing modes, especially when working with arrays or structures. Additionally, BX can hold values for arithmetic operations and can be used in conjunction with other registers to facilitate data manipulation. Its versatility makes it a key component in many assembly language programs.
What are the multipurpose registers in 8086 microprocessor?
8086 has four multipurpose registers. 1. AX (Accumulator Register) 2. BX (Base Register) 3. CX (Count Register) 4. DX (Data Register) By Aneeta Arshad
How do you write a code to complement the corresponding bit in bx if AX contains 6complement the 6th bit of BX in assembly?
To complement the 6th bit of the BX register in assembly language, you can use the XOR instruction. The 6th bit corresponds to the bit mask 0x20 (binary 0010 0000). The code would look like this: MOV AX, 6 ; Load AX with 6 (not directly relevant to complementing BX) XOR BX, 0x20 ; Complement the 6th bit of BX This will toggle the 6th bit of BX, effectively complementing it.
What are the Functions of DX register?
