摘要:
A synchronization scheme is provided for a multiprocessor system. In particular, a processor includes a buffer sync controller. The buffer sync controller is operative to allow or deny access by a subprocessor to shared data in a shared memory, such that a processor seeking to write data into or read data from the shared memory must ascertain certain shared parameter data processed by the buffer sync controller.

The present invention provides a secure buffer for use in data storage and encryption processing. Blocks or packets of data are passed to a secure buffer within a processor. The processor may be one of many coprocessors, and the secure buffer may be inaccessible to some or all of the coprocessors. Data may be partially or fully encrypted and stored within the secure buffer. Encryption may occur before or after storage in the buffer, or it may take place within the buffer itself. Optionally, the encrypted data may be sent to and retrieved from a shared memory that is accessible by other coprocessors.

Methods and apparatus enable the execution of processing sequences including the computation of a register index that is loaded into one of a plurality of registers, utilizing that index to identify another of the plurality of registers, and accessing data from or copying data to the indexed register to or from yet another register or a memory location.

Methods and apparatus provide for associating memory allocation table (MAT) entries with nodes in a binary tree such that the nodes and the entries are grouped into hierarchical levels, each entry including status information; associating the nodes and the entries with segments of a shared memory of a multi-processor system such that higher level nodes and entries are associated with larger numbers of segments of the shared memory and lower level nodes and entries are associated with smaller numbers of segments of the shared memory; initializing the MAT such that the status information of at least a plurality of entries indicates that the associated segment or segments of the shared memory are available for reservation; and selecting one entry in a group of entries in the MAT at a level corresponding to a desired size of the shared memory to be reserved.
摘要:
A system wherein raw material excavated from a plurality of pit faces on a mine are conveyed to and collected at a specific collecting location at the foot of a mountain by a plurality of vehicles and the degree of quality of collected raw material is then properly controlled at the specific collecting location is generally called a mining site control process. To practically execute such a mining control process, the degree of quality of conveyed raw material previously analyzed per each pit face and a quantity of conveyance thereof are confirmed at every time when the raw material is conveyed to the collecting location. Then, the degree of quality of raw material required to be next conveyed so as to allow the degree of quality predetermined as a target with respect to raw material to be collected is determined on the basis of the confirmed degree of quality and quantity of conveyance, and the manner of operating the respective vehicles is determined on a real time base so as to allow the thus determined degree of quality to be realized. When such a manner of operating the vehicles is to be determined, the most effective arrangement is selected for them in view of the representative state of actual operations of the vehicles and their loading capacity. All information in relation to such a mining site control process are electrically processed using a variety of sensors arranged at the respective pit faces and the collecting location, a computer installed in a control center and the like means.
