Apparatus and methods for extending functionality of memory controllers in a processor-based device are disclosed herein. In one aspect, a processor-based device provides a memory access intercept circuit that is communicatively coupled to a memory controller and a memory device. The memory access intercept circuit is configured to receive a memory write request that is directed to and received by the memory controller, and generates a write transaction identifier (ID) for the memory write request. The memory access intercept circuit then generates proxy write data containing the write transaction ID, and sends the proxy write data to the memory controller. The memory access intercept circuit subsequently intercepts the actual write data directed to the memory controller, and stores the write data in a write data buffer in association with the write transaction ID.

Extending functionality of memory controllers in a processor-based device

Apparatuses, systems, and methods for distributing a global counter value in a multi-socket SoC complex. In exemplary aspects, an apparatus comprises a first system-on-a-chip (SoC) in a first socket and a second SoC in a second socket. The apparatus further comprises a reset circuit coupled to the first SoC and the second SoC, a reset synchronization circuit coupled to the reset circuit, the first SoC, and the second SoC, and a global counter clock signal coupled to the reset synchronization circuit, the first SoC, and the second SoC. The reset synchronization circuit is configured to generate a global counter reset signal in response to a reset signal received from the reset circuit and to distribute the global counter reset signal to the first SoC and the second SoC substantially simultaneously.
