Hardware and software work together to allow computers to process and store data. The hardware components include the motherboard, CPU, memory, storage devices, ports and expansion cards. The motherboard contains the CPU and connections for other components to communicate. Software provides instructions to control the hardware.
DMA Versus Polling or Interrupt Driven I/O
Polling and Interrupt driven I/O concentrates on data transfer between the processor and I/O devices.
An instruction to transfer (mov datain,R0) only occurs after the processor determines that the I/O device is ready
Either by polling a status flag in the device interface or
Waits for the device to send an interrupt request.
Considerable overhead is incurred, because several program instructions must be executed for each data word transferred.
Instructions are needed to increment memory address and keeping track of work count.
With interrupts, additional overhead associated with saving and restoring the program counter and other state information.
