External parallel port to internal wishbone master interface :: Overview
Other project properties
This core is intended to be used as an interface between some functionality in an FPGA and an external microcontroller.
The external microcontroller provides a simple 8bit interface to control some functions within the FPGA. These functions are communicating using a wishbone compatible bus within the FPGA.
- 8 bit external interface to a simple parallel port of a regular microcontroller
- two cycle external bus transfers: first address, then data
- interrupt request flag
- bidirectional external data port
- wishbone compatible master interface to connect internal cores
