Abstract: An integrated circuit may include circuitry for accessing an associated die stack. The circuitry may receive temperature information as well as a plurality of operating parameters that help determine whether it may be desirable to reroute access commands or requests to one or more die in the stack. The circuitry may include a smart crossbar switch that implements an address translation or hashing function to help map the logical user address to a physical address space. Performing thermally aware traffic management in this way can ensure that acceptable timing margins are maintained in the system to minimize the probability of errors.

Abstract: One embodiment relates to a method of saving power in a memory subsystem. A first procedure is performed to save memory controller power by changing a clock toggle rate, and a second procedure is performed to save memory subsystem power by changing a clock frequency for the memory subsystem. A third procedure is performed to rebound back to full speed. Another embodiment relates to a memory subsystem which includes a memory controller, a memory, and a physical input/output interface. The memory controller performs at least a first procedure to save memory controller power by changing a clock toggle rate. Other embodiments and features are also disclosed.

Abstract: In one embodiment, the present invention includes a method for selecting a requester to service during an arbitration round, and updating counters associated with the selected requester including a command unit counter and a data unit counter, determining if the counters are in compliance with corresponding threshold values, and if so granting a transaction for the selected requester, and otherwise denying the transaction. Other embodiments are described and claimed.

Abstract: In the present method of implementing functioning of an encryption engine, a plurality of logic blocks are provided, each for running a function. Each function is run based on three variables, each of which may have a first or second value. The function is run with the first variable value selected as having its first value, and with the second and third variables having their actual values. The function is again run with the first variable value selected as having its second value, and again with the second and third variables having their actual values. An actual value of the first variable is determined, and the output of the logic block is determined by the actual value of the first variable.

Abstract: A system and associated methodology for performing a fast add rotate add operation is disclosed. Two separate addition functions conventionally separated by a shift operation are performed as a single operation thereby reducing the number of acts and resources required to perform the add rotate add operation.
