摘要： In a computer system having an operating system and a compressed main memory defining a physical memory and a real memory characterized as an amount of main memory as seen by a processor, and including a compressed memory hardware controller device for controlling processor access to the compressed main memory, there is provided a system and method for managing real memory usage comprising: a compressed memory device driver for receiving real memory usage information from the compressed memory hardware controller, the information including a characterization of the real memory usage state: and, a compression management subsystem for monitoring the memory usage and initiating memory allocation and memory recovery in accordance with the memory usage state, the subsystem including mechanism for adjusting memory usage thresholds for controlling memory state changes. Such a system and method is implemented in software operating such that control of the real memory usage in the computer system is transparent to the operating system.

摘要： A fault-tolerant clock system for providng digital timing signals (system clock signals) is provided by a plurality of clock sources. Each clock source receives as inputs the generated clock signals from all the other clock sources and contains receiver circuitry to derive a system clock signal from said clock sources which is the consensus clock signals of the other sources. Each clock source generates and distributes to the other clock sources a clock signal which is phase locked to the derived system clock from its clock receiver. In a system of (2r+2) clock sources (r+2) of them will remain phase locked to each other despite up to r clock source failures. Any clock receiver responsive to any (2r+1) of the clock sources can therefore derive a correct system clock despite up to r clock source failures.

摘要： A computing system and method employing a processor device for generating real addresses associated with memory locations of a real memory system for reading and writing of data thereto, the system comprising: a plurality of memory blocks in the real memory system for storing data, a physical memory storage for storing the pages of data comprising one or more real memory blocks, each real memory block partitioned into one or more sectors, each comprising contiguous bytes of physical memory; a translation table structure in the physical memory storage having entries for associating a real address with sectors of the physical memory, each translation table entry including one or more pointers for pointing to a corresponding sector in its associated real memory block, the table accessed for storing data in one or more allocated sectors for memory read and write operations initiated by the processor; and, a control device for directly manipulating entries in the translation table structure for performing page operations without actually accessing physical memory data contents. In this system, the actual data of the pages involved in the operation are never accessed by the processor and therefore is never required in the memory cache hierarchy, thus eliminating the cache damage normally associated with these block operations. Further the manipulation of the translation table will involve reading and writing a few bytes to perform the operation as opposed to reading and writing the hundreds or thousands of bytes in the pages being manipulated.

摘要： In a system with hardware main memory compression, the method of this invention monitors the physical memory utilization and if physical memory is near exhaustion it forces memory to be paged out, thus freeing up real memory pages. These pages are then zeroed, thus they are highly compressible and therefore reduce the physical memory utilization. Pages that have been forced out due to high physical memory utilization are not made available for allocation. In systems where operating system changes are permitted, this invention dynamically controls the minimum size of the free page pool and zeros pages upon freeing. When the physical memory utilization falls below a critical threshold the mechanism reduces the minimum size of the free pool to allow further allocation. In systems where operating system changes are not possible, pages are allocated by a module (e.g. Device driver) and then zeroed. When the physical memory utilization falls below a critical threshold this method frees some of the explicitly set aside pages.
摘要翻译：在具有硬件主存储器压缩的系统中，本发明的方法监视物理存储器利用率，并且如果物理存储器接近耗尽，则迫使存储器被分页出来，从而释放真实存储器页面。这些页面然后归零，因此它们是高度可压缩的，因此减少物理内存利用率。由于物理内存利用率高而被强制退出的页面不可用于分配。在允许操作系统更改的系统中，本发明在释放时动态地控制自由页面池和零页面的最小尺寸。当物理内存利用率低于临界阈值时，机制会降低可用池的最小大小以允许进一步分配。在不可能进行操作系统更改的系统中，页面由模块（例如，设备驱动程序）分配，然后归零。当物理内存利用率低于临界阈值时，此方法会释放某些明确设置的页面。

摘要： A nested frame communication protocol for communicating between computers. According to the nested frame communication protocol of the present invention, the computers communicate by transferring frames over communication links. The transmission of low priority frames may be interrupted in order to transmit high priority frames. After the transmission of the high priority frames is complete, the transmission of the low priority frames resumes. Processing states relating to interrupted frame transmissions are saved when the frame transmissions are interrupted. The processing states are restored when the interrupted frame transmissions are resumed.

摘要： A system having a plurality of redundant channels operating in tight synchronism wherein input information received in one or more of said channels is distributed to all the other channels. The received information in each channel is retransmitted to suitable voter circuitry in each channel so as to provide one or more voted outputs in each channel based on the distributed and retransmitted information from all the channels. The voted outputs from all unfailed channels are substantially identical and the voted output from a failed channel will not be identical to that of the unfailed channels.
