What is the use of Intel 8257 microprocessor?
Its a Programmable Direct Memory Access (DMA) controller.
What is Difference between 8155 and 8255 microprocessor?
Neither the 8155 nor the 8255 are considered to be microprocessors. The 8155 is an integrated RAM, IO, and Timer device designed for the 8085. The 8255 is an Programmable IO 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
How do you start parallel port interfacing?
The old workhorse 8255 PPI (Programmable Peripheral Interface) is a good place to start.
What is 8255?
8255 is a programmable peripheral device, a chip used to control peripheral devices connected to/with in a computer in the 8086 based machines.
