Microcontroller including alternative links between peripherals for resource sharing

摘要

A system includes one or more master modules configured to execute instructions embedded in non-transitory machine-readable media and controllable by a processor. The system also includes one or more peripheral modules that are configured to execute instructions embedded in non-transitory machine-readable media and controllable by the processor. The system also includes a system bus with instructions embedded in a non-transitory machine-readable medium and configured to allow data transfer between the processor and the one or more peripheral modules. A data processing module of the one or more peripheral modules includes a master interface and a slave interface. Both master and slave interfaces are coupled to the system bus.

1. A system comprising:
one or more master modules; a data processing module; and a system bus that is configured to perform operations comprising:
receiving an instruction from a master module for a transfer of data to a destination;determining whether additional processing is associated with the transfer; andbased on a determination that additional processing is associated with the transfer, redirecting the transfer to the data processing module by setting an extra address bit in the system bus.
