SPI Engine#

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.

The core component of the SPI Engine framework is a lean but powerful fully programmable execution module, which implements the SPI bus control logic. The SPI Engine execution module is controlled by a command stream which is generated by a separate module. Different command stream manager modules are available and can be used depending on the system requirements. For example a software controlled memory mapped command stream offers high flexibility, while a offload core which executes a pre-programmed command stream when triggered by an external event allows for very low latency response times. By using a SPI Engine interconnect it is possible to connect multiple command stream manager modules to a SPI Engine execution module.
