SUBSYSTEM CONTROLLERS
1. Some parts of the computer are able to transfer data to and from the computer's memory without passing through the CPU. This operation is called direct memory access, or DMA, and it is handled by а chip known as the DMA controller. The main purpose of the DMA controller is to allow disk drives to read or write data without involving the microprocessor. Because disk I/О is relatively slow compared to CPU speeds, DMA speeds up the computer's overall performance quite а bit.
2. The clock generator supplies the multiphase clock signals that coordinate the microprocessor and the peripherals. The clock generator produces а high-frequency oscillating signal. For example, in the original IВМ РС, this frequency was 14.31818 megahertz (MHz, or million cycles per second); in the newer machines, the frequency is higher. Other chips that require а regular timing signal obtain it from the system clock generator by dividing the base frequency by а constant to obtain the frequency they need со accomplish their tasks.
3. The programmable interval timer generates timing signals at regular intervals controlled by software. The chip can generate timing signals on three different channels at once (four channels) and more in other systems.
The timer's signals are used for various tasks. One essential timer function is to generate а clock-tick signal that keeps track of the current time of day. Another of the timer's output signals can be used to control the frequency of tones produced with the computer's speaker.
