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 8257 chip means?
The 8257 is a three channel DMA controller.
What is the use of Intel 8257 microprocessor?
Its a Programmable Direct Memory Access (DMA) controller.
What is difference between 8237 and 8257 DMA controllers?
8237 provides better performance, compared to 8257. The distinctive feature of 8237 chip is that it provides, many programmable control and dynamic reconfigurability features which enhance the data transfer rate of the system remarkably
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
