9. Registers: are high speed storage areas within the CPU but has the least storage capacity .. Following are some commonly used registers: Accumulator : This is the most common register, used to store data taken out from the memory. General Purpose Registers : This is used to store data intermediate results during program execution. MAR : Memory Address Register are those registers that holds the address for memory unit. MDR: Memory Data Register stores data received from the memory and sent from the memory. PC: Program Counter points to the next instruction to be executed. IR: Instruction Register holds the instruction which is currently been executed. 13-May-20 NIMMY RAJU,AP,VKCET,TVM 9
