In one embodiment, an apparatus includes: a fabric circuit to couple between a plurality of managers and a memory; and multi-bank memory control circuitry coupled to the fabric circuit and to couple to a plurality of banks of the memory and including a plurality of first ports to receive memory requests from the plurality of managers, The multi-bank memory control circuitry is to enable each of the plurality of managers to access the memory in parallel. A global monitor is coupled to the multi-bank memory control circuitry and includes a plurality of second ports and a plurality of state machines, each of the plurality of state machines to be associated with one of the plurality of managers. Each of the plurality of state machines is configured to enforce exclusivity of a memory region on behalf of a manager and concurrently enable non-exclusive access to the memory region.

Global monitor for multi-port memory controller

A multi-bus protocol memory controller is disclosed. The memory controller utilizes shim circuits to translate between the various bus protocols used in the System on a Chip (SoC) and the bus protocol used by the memory controller. The use of shim circuits reduces the number of bridges required in the SoC and also increases performance. The memory controller is designed such that it may interface with any bus protocol, requiring only the design and inclusion of a shim circuit for that bus protocol.
