Microprocessor SPHL instruction copies the content of H-L register pair to the _________. PSW Stack Pointer B-C D-E PSW Stack Pointer B-C D-E ANSWER DOWNLOAD EXAMIANS APP
Microprocessor A good assembly language programmer should use general purpose registers rather than memory in maximum possible ways for data processing. This is because: Data processing with registers is easier than with memory Data processing with memory requires more instructions in the program than that with registers Data processing with registers takes fewer cycles than that with memory Of limited set of instructions for data processing with memory Data processing with registers is easier than with memory Data processing with memory requires more instructions in the program than that with registers Data processing with registers takes fewer cycles than that with memory Of limited set of instructions for data processing with memory ANSWER DOWNLOAD EXAMIANS APP
Microprocessor In a computer the data transfer between hard disk and CPU is nearly the same as that between diskette and CPU. True False True False ANSWER DOWNLOAD EXAMIANS APP
Microprocessor The output data lines of microprocessor and memories are usually tristated because More than one device can transmit over the data bus at the same time More than one device can transmit information over the data bus by enabling only one device at a time The data line can be multiplexed for both input and output It increases the speed of data transfer over the data bus More than one device can transmit over the data bus at the same time More than one device can transmit information over the data bus by enabling only one device at a time The data line can be multiplexed for both input and output It increases the speed of data transfer over the data bus ANSWER DOWNLOAD EXAMIANS APP
Microprocessor PUSH B instruction in 8085 microprocessor causes the contents of registers B & C to be transferred in the stack and and the registers get cleared the contents of register B & C to be copied in the stack the contents of register B only to be copied in the stack registers B & C to be cleared the contents of registers B & C to be transferred in the stack and and the registers get cleared the contents of register B & C to be copied in the stack the contents of register B only to be copied in the stack registers B & C to be cleared ANSWER DOWNLOAD EXAMIANS APP
