Multicore shared cache operation engine

1. A processing system comprising:

one or more processors;

a cache memory coupled to the one or more processors; and

a memory controller comprising:

one or more trigger control channels configured to:

receive configuration information for a trigger control channel of the one or more trigger control channels, the configuration information defining a first one or more triggering events;

receive a first memory management command;

store the first memory management command;

detect the first one or more triggering events; and

trigger the stored first memory management command based on the detected first one or more triggering events.

2. The processing system of claim 1 , wherein the first one or more triggering events comprise at least one of receiving an event on a shared messaging interface or a set register bit value command received on a local bus.

3. The processing system of claim 1 , wherein the first one or more triggering event comprises an event received on a shared messaging interface.

4. The processing system of claim 1 , wherein the received configuration information comprises an indication of an interface to use to obtain the first memory management command.

5. The processing system of claim 1 , wherein the configuration information is obtained from a peripheral.

6. The processing system of claim 1 , wherein the memory controller further comprises return messaging circuitry configured to:

receive a response to a memory access command;

format the response based on a memory access command type; and

output a formatted memory access command.

7. The processing system of claim 6 , wherein formatting the response comprises formatting a local event based on the response, and wherein the one or more trigger control channels are configured to trigger a second memory management command based on the local event.

8. The processing system of claim 1 , wherein the detected first one or more triggering events comprise at least one of a receiving an event on a shared messaging interface or a set register bit value command received on a local bus.

9. The processing system of claim 1 , wherein the one or more trigger control channels include two or more trigger control channels configured to:

detect a second one or more triggering events;

trigger a second memory management command based on the detected second one or more triggering events; and

wherein the memory controller is configured to arbitrate between the first and second memory management command.

10. A memory controller device coupled to one or more processors, the memory controller device comprising:

one or more trigger control channels configured to:

receive configuration information for a trigger control channel of the one or more trigger control channels, the configuration information defining a first one or more triggering events;

receive a first memory management command;

store the first memory management command;

detect the first one or more triggering events; and

trigger the stored first memory management command based on the detected first one or more triggering events.

11. The memory controller device of claim 10 , wherein the first one or more triggering events comprise at least one of receiving an event on a shared messaging interface or a set register bit value command received on a local bus.

12. The memory controller device of claim 10 , wherein the first one or more triggering event comprises an event received on a shared messaging interface.

13. The memory controller device of claim 10 , wherein the received configuration information comprises an indication of an interface to use to obtain the first memory management command.

14. The memory controller device of claim 10 , wherein the configuration information is obtained from a peripheral.

15. The memory controller device of claim 10 , wherein the memory controller further comprises return messaging circuitry configured to:

receive a response to a memory access command;

format the response based on a memory access command type; and

output a formatted memory access command.

16. The memory controller device of claim 15 , wherein formatting the response comprises formatting a local event based on the response, and wherein the one or more trigger control channels are configured to trigger a second memory management command based on the local event.

17. The memory controller device of claim 10 , wherein the detected first one or more triggering events comprise at least one of a receiving an event on a shared messaging interface or a set register bit value command received on a local bus.

18. The memory controller device of claim 10 , wherein the one or more trigger control channels include two or more trigger control channels configured to:

detect a second one or more triggering events;

trigger a second memory management command based on the detected second one or more triggering events; and

wherein the memory controller is configured to arbitrate between the first and second memory management command.

19. A method for accessing memory by a memory controller, comprising:

receiving configuration information for a trigger control channel of one or more trigger control channels, the configuration information defining a first one or more triggering events;

receiving a first memory management command;

storing the first memory management command;

detecting the first one or more triggering events; and

triggering the stored first memory management command based on the detected first one or more triggering events.

20. The method of claim 19 , further comprising:

receiving a response to a memory access command;

formatting the response based on a memory access command type; and

outputting a formatted memory access command.
