What is the difference between 8051 and arm apart from its features?
arms executes aiimost all instruction in one cycle controller take more than one cycle in almost all instruction arm is risc based architecture con. is cics based architecture but having less no of instruction as compare to arm arm is based on load store architecturen i.e. data processing instruction can not access memory directly data has been store in reg controll access memory directly arm have conditional data processing
When an instruction is executed in a programm what happens in the processor memory?
All the programming instructions whcih are basically in the assembly code has the corresponding hexadecimal code.the microprocessor understand or interprets what this code is and based on that it performs operation for eg HLT which had hexcode 76 the microprocessor understands76 as tha halt instruction and based on that it halts or terminates the program Anand bhat(mca@kiit-870024)
How does a microprocessor know whether the next byte is an instruction or data?
A microprocessor know whether the next byte is an instruction or data because the microprocessor knows for what it is looking. The bus, on the other hand, for an 8085 based system, knows an opcode from data by looking at S0 and S1 when IO/M- is low. If both are high, it is an opcode, otherwise it is data.
What is the instruction to add the data in register B to the data in accumulator?
add B
What is considered a function of the instruction set for the CPU?
The Functions of the instruction set is to instruct All CPU's with a set of instructions: Tells the CPU where to find data When to read the data What to do with the data. Hope that helps Don
What is a programme or set of instruction called?
a program is called a program. a set of instructions is called a manual.
What register points to the next instruction?
actually register holds the data..there are 6 register which are temporary registers..program counter holds the address of next instruction to be fetched..instruction register holds the currently executed data...
What is instruction cycle with interrupts?
The instruction cycle is the basic operation cycle in a computer. This is what will take in data, process it and execute as required.
Is a process that allows the CPU to receive a single instruction and then execute it on multiple pieces of data rather than receiving the same instruction each time each piece of data is received?
"SIMD, which stands for 'single instruction, multiple data,' is a process that allows the CPU to receive a single instruction and then execute it on multiple pieces of data rather than receiving the same instruction each time each piece of data is received."(Pg. 434, A+ Guide to Managing and Maintaining Your PC)
PUSH Instruction in 8085 Micro processor?
Push instruction pushes two byte of data on the top of the stack.
What is data register?
It is used to hold data or the memory address that contains either the next place of data or an instruction that is to be used .
Need another word for Information?
instruction, data, or erudition.
