Opcodes are generated during the compilation process of programming languages. They are the machine-level instructions that represent the operations to be performed by the computer's processor. The compiler translates high-level code into a series of opcodes that can be understood and executed by the hardware.

Is there any possible justification for an instruction with two opcodes?

An instruction only has one opcode. There may be two opcode bytes, or there may be different fields in the assembly code of the instruction, but the bit pattern of an instruction will always generate the same results. There are some results that can be generated with two different opcodes. SUB A and XRA A, for instance, both clear the accumulator, but they are two different opcodes for two different instructions.

What is pseudo-opcodes?

Pseudo-opcodes are not actual machine-level instructions but instead are mnemonic codes used by programmers to simplify assembly language programming. They are translated into one or more real opcodes by the assembler during the compilation process.

What are the different MIPS ALU opcodes used for performing arithmetic and logical operations in a MIPS processor?

The MIPS ALU opcodes are used for performing arithmetic and logical operations in a MIPS processor. Some common opcodes include ADD (addition), SUB (subtraction), AND (logical AND), OR (logical OR), and XOR (exclusive OR).


How do you add and subtract 16 bit numbers using 8051 microprocessor?

The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.


What set of instructions tell the computer what to do?

A program is a set of instructions that tell a computer what to do. In the computer, those instructions are called opcodes and make up an instruction set.


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.


How the compiler conver the hll statements into machine language?

The assembler's role is most important.it converts the high level language statements into machine level language statements with the help of some operand and opcode specifications.there is first mnemonic opcode specification.here instead of writing binary opcodes,mnemonic opcodes can be specified.advantage of using mnemonic opcodes are:program becomes readable.debugging becomes simple.so it is the responsibility of the assembler to replace each mnemonic opcode by its respective binary opcode.also there is symbolic operand specification.in that,instead of specifying the addresses of instructions and data,symbols can be used.advantage of using the symbolic operand is that the program can be modified with no overhead.it is the responsibility of assembler to replace each symbol by its address.
