SPI Engine is a highly flexible and powerful SPI controller framework. It consist out of multiple sub-modules which communicate over well defined interfaces. This allows a high degree of flexibility and re-usability while at the same time staying highly customizable and easily extensible. Currently included are four components: * SPI Engine execution module: The excution module is responsible for handling the low-level physical interface SPI logic. * SPI Engine AXI interface module: The AXI interface module allows memory mapped acccess to a SPI bus control stream and can be used to implement a software driver that controls the SPI bus. * SPI Engine offload module: The offload module allows to store a predefined SPI Engine command and data stream which will be send out when a external trigger signal is asserted. * SPI Engine interconnect module: The interconnect module allows to combine multiple control streams into a single stream giving multiple control modules access to a execution module.
