Input Output Transfer Techniques

Input Output Transfer Techniques: In Input Output Transfer Techniques, the system requires the transfer of data between external circuitry and the microprocessor. In this section, we will discuss different ways of I/O transfer. Program controlled I/O or Polling control . Interrupt program controlled I/O or interrupt driven I/O. Hardware controlled I/O. I/O controlled by Handshake […]

Input Output Interfacing Techniques

Input Output Interfacing Techniques: The most of the microprocessors support isolated I/O system. It partitions memory from I/O, via software, by having instructions that specifically access (address) memory, and others that specifically access I/O. When these instructions are decoded by the microprocessor, an appropriate control signal is generated to activate either memory or I/O operation. […]

Memory Interfacing in 8085

Memory Interfacing in 8085: Memory is an integral part of a microprocessor system, and in this section, we will discuss how to interface a memory device with the microprocessor. The Memory Interfacing in 8085 is used to access memory quite frequently to read instruction codes and data stored in memory. This read/write operations are monitored […]
