Question 1 DMA Controller in 8086 The problem of slow data transfer between input-output port and memory is avoided by implementing Direct Memory Access (DMA) technique. This is faster as the microprocessor/computer is bypassed and the control of address bus and data bus is given to the DMA controller. Discuss in detail with the help of diagrams, the interface and the operation of DMA controller in single mode and in cascaded mode in 8086

Step 1
What is DMA? DMA stands for Direct Memory Access. It is a technique used in computer systems to transfer data between memory and peripheral devices without involving the microprocessor. This allows for faster data transfer as the microprocessor is bypassed. Show more…

Microprocessor 68000 Motorola system consists of three (3) main components which are Central Processing Unit (CPU), memory, and input/output devices. List down the main components of the CPU and describe each function. Illustrate and properly label the programming software model of Motorola 68000. Explain the details of data register, address register, stack pointer, program counter, all the buses, and basic memory map in terms of size only. Using an appropriate flow diagram, explain three microprocessor operations during program execution: major stages of basic.
