Abstract: A cache may include multiple request handling pipes, each of which may further include multiple request buffers, for storing device requests from one or more processors to one or more devices. Some of the device requests may require to be sent to the devices according to an order. For a given one of such device requests, the cache may select a request handling pipe, based on an address indicated by the device request, and select a request buffer, based on the available entries of the request buffers of the selected request handling pipe, to store the device request. The cache may further use a first-level and a second-level token stores to track and maintain the device requests in order when transmitting the device requests to the devices.

Abstract: Various method and apparatus embodiments for selecting tunable operating parameters in an integrated circuit (IC) are disclosed. In one embodiment, an IC includes a number of various functional blocks each having a local management circuit. The IC also includes a global management unit coupled to each of the functional blocks having a local management circuit. The management unit is configured to determine the operational state of the IC based on the respective operating states of each of the functional blocks. Responsive to determining the operational state of the IC, the management unit may provide indications of the same to the local management circuit of each of the functional blocks. The local management circuit for each of the functional blocks may select one or more tunable parameters based on the operational state determined by the management unit.
