Software-hardware method of serial interface controller implementation

A software-hardware method of serial interface controller implementation is proposed which includes separate processing of data link and physical layer functions The data link layer functions are implemented in software using a microcontroller (MC), and physical level functions -in hardware using programmable logical device (PLD). The proposed method provides optimal ratio of hardware and software costs for interface controller (IC) implementation, and effective utilization of MC computing power. Based on this method a structure of the universal serial interface controller is proposed.
