How an assembler converts assembly mnemonics to machine language?
Each mnemonic maps directly to a machine instruction code, known as an opcode. Some mnemonics map to more than one opcode, however the instruction's operand types will determine which specific opcode will be generated.
How do you write object code for format 2 instruction in sic xe machine?
To write object code for a format 2 instruction in the SIC/XE machine, you need to identify the opcode for the instruction and the registers involved. The object code consists of the 8-bit opcode followed by the 4-bit binary representation of the two registers. The format is typically structured as follows: the first 8 bits for the opcode, the next 4 bits for the first register, and the last 4 bits for the second register. Finally, you concatenate these binary values to produce the final object code.
What translates a program written in Assembly language into machine code?
Well, let's say you have the following Assembler statement: MOV AX, 0005 Each processor (depending on the processor architecture, being some of them: SPARC, Intel 80x86, Motorola...) translates each Assembler mnemonic and register into Machine Code according to an Opcode Table. Think of an Opcode Table this way: Instruction OpCode ----------------------------------- MOV A1 ADD A2 SUB A3 MUL A4 DIV A5 ... AX B0 BX B1 CX B2 ... Each mnemonic/register has its corresponding hex code for the processor to understand the operation, so: MOV AX, 0005 Could be translated as: A1 B0 0005 Hopefully this gives you an idea of how a processor assembles code and generates machine code.
What are the difference between opcode and operand?
An opcode is an instruction. An operand is information used by the opcode. Not all opcodes require operands.
what tool used to convert C++ source code into executable machine code?
Compliers are used to convert C++ into assembly code. Then a tool called an "assembler" converts that code into machine code. Finally, a "linker" connects all of those machine code files into a single executable.

What is the content of java byte code?
It is partial with opcode and processor code. It is meaningless when we see it on our eyes, but it provides info instructions to Java Virtual Machine to execute that.
How does microprocessor differentiate between data and instruction code?
i) Instruction code deals only with mnemonics and its corresponding opcode but data code refers to your data like 10h which is always of 8 bits or a particular address say 8080h which is of 16 bits. ii) Data is your input to the instruction but an opcode is native to your machine. iii) Data is user specific instruction while opcode is machine specific instruction iv) You can alter data code but you cannot modify an instruction opcode.

What are the examples of compiler?
basically compiler is that convert an object code in to machine code and machine code is directly understood by a computer. assembler and interpreter are the examples of compilers. assembler is used to convert object code of assmebly language in machine code.
What are the Machine Cycles For Inr M Instruction?
3 for opcode fetch, 1 for opcode decode, 3 for operand fetch, and 3 for opcode store, for a total of 10, not including wait states.

What is Op code and Operand?
An opcode (operation code) is a part of an instruction in machine language that specifies the operation to be performed, such as addition, subtraction, or data movement. The operand, on the other hand, is the part of the instruction that provides the necessary data or addresses required for the operation, indicating the target of the operation or the data to be manipulated. Together, the opcode and operand define the specific action and the data involved in machine-level programming.
IS OPCODE FETCH MACHINE CYCLE ENOUGH FOR THE INTRUCTION MOV MA IN 8085 TIMING DIAGRAM?
In the 8085 microprocessor, the opcode fetch machine cycle is not sufficient on its own for executing the MOV MA instruction. While the opcode fetch cycle is responsible for retrieving the instruction from memory, additional machine cycles are required to perform the data transfer or execution of the instruction. Specifically, the MOV MA instruction involves both an opcode fetch cycle and a memory access cycle to complete the operation. Therefore, multiple machine cycles are necessary for executing this instruction effectively.
What happens to ip after completion of fetch of instruction code?
IP is incremented after fetch of instruction opcode. Specifically, IP is incremented by the number of opcode bytes.
