    摘要: A memory management unit is configured to receive requests for memory access from a plurality of I/O devices. The memory management unit implements a protection mode wherein the unit prevents memory accesses by the plurality of I/O devices by mapping memory access requests (from the I/O devices) to the same set of memory address translation data. When the memory management unit is not in the protected mode, the unit maps memory access requests from the plurality of I/O devices to different respective sets of memory address translation data. Thus, the memory management unit may protect memory from access by I/O devices using fewer address translation tables than are typically required (e.g., none).

    摘要: A mechanism is provided for minimizing system power in the data processing system with fast convergence. A current aggregate system power value is determined using a current thermal threshold value. For each potential thermal threshold value in a set of potential thermal threshold values, a determination is made as to whether there is a potential thermal threshold value that results in a potential aggregate system power value that is lower than the current aggregate system power value. Responsive to identifying an optimal potential thermal threshold value from the set of potential thermal threshold values that results in minimum aggregate system power value that is lower than the current aggregate system power value, the optimal potential thermal threshold value is set as a new thermal threshold value.
