What is the difference between Pseudo instructions and instruction?

What is the difference between instruction and pseudo-instruction?

A pseudo-instruction : A symbolic representation in a compiler or interpreter. An instruction : a simple statement in any language that defines a task or computation etc.

What is the Difference between machine op and pseudo op?

A pseudo-op is an assembly language instruction that specifies an operation of the assembler i.e about the base register & its contents e.g. USING instruction. On the other hand, a machine-op instruction. That represents a machine instruction to the assembler e.g. BR instruction is a machine-op instruction

What is pseudo instructions?

A pseudo-instruction doesn't actually exist in the instruction set of a processor. A pseudo-instruction will be a convenient single name for one or more actual instructions. A common example is the unconditional jump instruction. Normally the syntax for this instruction would be: jmp address ...but the assembler might actually translate that into: cmp t0 r0 r0 jmp t0 address Which is basically checking to see if the zero register is equal to the zero register, and if so jump. Since this will always be true, it will always jump.

What is the basic Difference between flow chart and pseudo-code?

what's the difference between flow chart and structure diagrams and pseudo code

What is the difference between Mnemonics and hexadecimal representation?

Mnemonics is a method of remembering things by associascation. Hexadecimal is a number system. 0-9 are as usual and then a(10) b(11) c(12) d(13) e(14) f(15)

What is the difference of source code object code and pseudo code?

Source code is a sequence of executable instructions written in a particular language. Pseudo code is a sequence of non-executable instructions. It is also called algorithm written in plain English

Why is assembly language considered easier for humans to program than machine language?

Assembly is signficantly shorter and easier to remember than the equivilant machine instructions. Assembly instructions are human readable characters, for which a direct translation exists to the binary machine code instructions. Pseudo example: add <- assembly instruction 1010101010 <- machine instruction

What are the instructions that are not getting translated but act as a directive?

Pseudo instructions.

What is the difference between Pseudo-code and an actual computer software program?

the difference between that two words is the spelling, numbers of letters and the first letter in that two particular words

Assembly language to machine language translation is?

Assembly language to machine code translation is a "one to one" translation process, as every individual instruction expressed in the assembly language corresponds to exactly one machine instruction. Note this does not hold for pseudo instructions or expanding macros, which are supported by some assemblers.

Write comparisons based on the following parameters of instruction set architecture between Intel and mips architecture?

Dear, Class of ISA ( Instruction Set Architecture ) INTEL : The complete Intel Architecture instruction set includes the integer, floating-point, MMX technology, and system instructions. The instruction descriptions are arranged in alphabetical order. For each instruction, the forms are given for each operand combination, including the opcode, operands required, and a description. Also given for each instruction are a description of the instruction and its operands, an operational description, a description of the effect of the instructions on flags in the EFLAGS register, and a summary of the exceptions that can be generated. MIPS instructions fall into 5 classes: Arithmetic/logical/shift/comparison Control instructions (branch and jump) Load/store Other (exception, register movement to/from GP registers, etc.) Memory Addressing & Addressing modes :Intel : The addressing modes in Intel are, Immediate addressing mode Register addressing Direct addressing Indirect addressing Indexed MIPS has 5 ways of addressing data Immediate: data is in instruction itself Register: register number in instruction tells which register contains data Base/offset: offset value added to base register PC-relative: offset added to PC Pseudo direct: offset from instruction merged with PC Type and size of Operands :Intel : Dear, Class of ISA ( Instruction Set Architecture )INTEL : The complete Intel Architecture instruction set includes the integer, floating-point, MMX technology, and system instructions.

MIPS : The type of operands that it can handle are bit string, character, decimal, integers and floating point numbers. The size of operands in Intel are 8-bit, 16-bit, 32-bit integers and 32-bit and 64-bit IEEE 754 floating-point. Control Flow Instructions : Intel : Branch and Jump instructions MIPS : BRANCH and JUMP are the control instructions in MIPS " I hope this will help you"

Assembler directives in microprocessor?

Manual coding of 8086 is difficult hence we use a assembler or a compiler. Note that the microprocessor should be able to interpret your discussions via the program. Suppose if the instruction corresponds to word(16 bits), we use assembler directive WORD PTR, but when assembler is contacting the processor it sets a bit called 'w' indicating its a byte operation.
