A method is disclosed to estimate energy consumed by a component in a microcontroller during operation including identifying 'event' activities, where the energy consumed by the component may be determined by the number of events executed by the component, and “duration” activities, where the energy consumed may be determined by the duration of time required to execute of the activity, and determining the energy consumed by the component based on the number of events/duration of time and an energy coefficient which corresponds to the amount of energy consumed by the component to execute the activity, under given operating conditions. In an embodiment, data transfers at a bus interface may represent event activities. Apparatus to estimate the energy consumed is disclosed including bus monitors to receive signals representing data transfers at a bus interface and provide signals indicating the number of data transfers executed.

Microcontroller energy profiler

Embodiments described herein provide for an emulation system that supports efficiently generating outgoing messages to a test bench. The emulation system transmits the outgoing messages to the test bench various busses and interfaces. The compiled virtual logic writes the outgoing messages into memories of the emulation chips for queuing, and notification messages associated with the queued outgoing messages. A traffic processor transfers from memories to the test bench using buses and interfaces. The traffic processor reads a notification message from memory to identify the storage location with a corresponding queued outgoing message. The traffic processor then transmits DMA requests to I/O components (e.g., DMA engines) to instruct the I/O components to transfer the queued outgoing message to the host device.
