Block diagram of 8257 dma controller?
it is a device to transfer the data directly between io device and memory without through the cpu so it performs a high-speed data transfer between memory and io device
What are the examples of microprocessors?
E.g. 8085, 8086, 8255, 8051, 6800, 8257, 8251 and many more...
Why A0 to A3 lines are bidirectional in 8257?
The A0 to A3 lines in the 8257 DMA controller are bidirectional because they are used for both address and data transfer. During the address phase, these lines carry the address of the memory location being accessed, while during the data transfer phase, they transmit the actual data. This dual functionality reduces the number of required pins on the chip, making it more compact and efficient in managing data transfers between memory and peripherals.
What are tristate lines of dma 8257?
Tristate lines in the context of the DMA 8257 refer to the control lines that can be in one of three states: high, low, or high impedance (floating). This high impedance state allows multiple devices to share the same bus without interfering with each other, as it effectively disconnects the device from the bus when it is not actively transmitting data. The tristate feature is crucial for managing data transfers between the CPU and peripherals in a system, enabling efficient communication and minimizing conflicts.
What is the phone number of the Parmly Billings Library Bookmobile in Billings?
The phone number of the Parmly Billings Library Bookmobile is: 406-657-8257.
What is auto load in 8257 DMA controller?
Auto load in the 8257 DMA controller refers to a feature that allows the DMA controller to automatically load the address and count registers from a specified memory location after each DMA transfer. This capability enables the controller to perform multiple transfers without requiring the CPU to intervene between each operation. By using auto load, it simplifies the programming of DMA operations, particularly for repetitive data transfers. This feature is useful in applications where continuous data movement is needed, such as in audio or video processing.
