Memory Register

Some of  CPU general purpose registers – Intel, arsitektur x86 :

• EAX => accumulator.

used to perform calculations and used to store the return value from the function call. base of operations such as addition, subtraction, comparisons using these registers.

• EBX => base.

can be used to store data

• ECX => counter.

 can be used for looping, this register counts down.

• EDX => data.

used for addition to the EAX register. can be used for more complex calculations such as: division or subtraction by adding extra data to memfalisitasi calculation.

• ESI => source index,

used for the detention of the location of the input data

• EDI => destination index.

contains a pointer location where the result of the operation data is stored.

• EIP => instruction pointer.

 contains a pointer location where the next instruction will be executed by the CPU.

• EBP => base pointer.

also commonly called the frame pointer (base pointer is the terminology intel). used to reference all function parameters and local variables in stack frame.
