Session 04 Where the Arithmetic Operations Are Done In A Complete Flashcards
Where the arithmetic operation are done in a computer?
In ALU - arithmetic and logic unit
What ALU can perform
Addition, subtraction, AND operation
operands that need ALU to do task store until perform the task in?
Processor Register (IR)
What’s processor register (IR)
It is local storage space inside a processor that holds data being processed by CPU
What’s Accumulator?
Special purpose register that store the result from the ALU
What components help ALU to perform
Accumulator AC
Instuction register IR
Program counter PC
Memory address register MAR
index register IR
Memory buffer register MBR
What’s Control Unit do?
Interpret the instuction and provide necessary signals to the ALU for operations
What’s Instuction Register do?
Hold the Instructions being executed inside the processor
To support IR they use 2 special registres what are those?
MAR memory address register
MBR memory buffer register
What MAR memory address register do?
Indicate the address of the information stored in the memory that has to fetch
What’s MBR memory buffer register do?
MBR keeps the data before bringing it to special register
How can register(A, B) can recive value?
From memory, general-perpouse register GPR, Accumulator
What’s Status register SR/ Flat register FR do
This register holds the status of the operation which has completed recently
