To transport data between memory and I/O devices, the computer system's CPU interfaces with them. However, the CPU communicates with memory and I/O devices in distinct ways. Either directly or through the Cache memory, the CPU can connect with the memory. The communication between the CPU and the I/O devices, on the other hand, is normally accomplished through the use of an interface.
In this “Input and Output Interfaces - Microprocessors” you will learn about the following topics:
- Internal Communication
- Processor to Memory Communication
- The Processor Perform the Following Steps to Read the Data, the Processor Perform the Following Steps for Writing the Data
