摘要： Methods and an apparatus for storing information in a processing device with flexible security are disclosed. In one embodiment, an apparatus processes back-to-back write and read operations without stalling the processor. A cache memory subsystem buffers write operations between a central processing unit (CPU) and the cache memory subsystem. Included in the cache memory subsystem are a tag memory, a data memory and a store buffer. The store buffer is coupled to both the data memory and the tag memory. Additionally, the store buffer stores a write operation.

摘要： An apparatus and method for providing an accurately regulated flow of liquid medium to a device mounted in or on a rotor of a centrifuge, comprises a scoop on the rotor having a mouth opening forwards in the direction of rotation, with a duct connecting the mouth to the device; the liquid medium being projected as a jet into the path of the rotating scoop so that the mouth chops out a mid-portion of the jet during each revolution, and feeds it to the device. Rotation rates are high, typically 50,000 rpm for devices like liquid flow density balances for mass detection, but may be less and/or variable with SFFF devices.

摘要： The invention concerns complexity management of a receiver in a multi-access/user communication system where interference exists. For example, but not limited to, multi-user detection at the receiver in the uplink of a code division multiple access DS/CDMA system. The invention provides a method for power management and decoding schedule optimisation by deriving (40) an extrinsic information transfer (EXIT) function for an interference canceller and a plurality of decoders. Then, determining (42) a power level for each of the plurality of users based on the derived EXIT functions; and then deriving (44) a decoding schedule for the plurality of decoders based on the derived EXIT functions and determined power levels. It is an advantage of the invention that optimization is broken into two parts. There is no trade-off between computational complexity (number of iterations) and the improvement in bit error rate performance at a given signal-to-noise ratio. Using the invention, large gains in receiver sensitivity (i.e. in power efficiency and/or spectrum efficiency therefore reducing interference from the terminals) and computational complexity can be achieved simultaneously.
摘要翻译：本发明涉及存在干扰的多址/用户通信系统中的接收机的复杂度管理。例如但不限于在码分多址DS / CDMA系统的上行链路中的接收机处的多用户检测。本发明提供一种通过导出（40）干扰消除器和多个解码器的外在信息传输（EXIT）功能来对功率管理和解码进度优化的方法。然后，基于导出的EXIT功能确定（42）多个用户中的每一个的功率电平; 然后基于导出的EXIT函数和确定的功率电平导出（44）多个解码器的解码调度。本发明的优点是将优化分为两部分。在给定的信噪比下，计算复杂度（迭代次数）和误码率性能的改善之间不存在折衷。使用本发明，可以同时实现接收机灵敏度（即，功率效率和/或频谱效率，从而减少来自终端的干扰）的大增益和计算复杂度。

摘要： A disc player that incorporates a single piece disc enclosure and a chassis section is described. The incorporation of the disc enclosure and the chassis section into a single piece eliminates the requirement for a separate damping system. As well as reducing the cost of manufacturing the device this also allows for the tolerance between the spindle motor and the disc enclosure to be precisely controlled so enabling miniaturization of the disc player.

摘要： Methods of maintaining cache coherency of a virtual cache memory system in a data processing system are disclosed. The entries of the virtual cache memory include physical address information and logical address information. A memory access operation may be initiated on one or more predetermined memory locations based on physical address information. A determination may be made if the memory access operation may involve cache coherent memory. If the memory access operation may involve cache coherent memory, then a cache coherency command may be issued that contains physical address information of the memory access operation. Based on the cache coherency command and the physical address information, a determination may be made if there is a match between the physical address information of the memory access operation and the physical address information stored in the virtual cache. If there is a match, then a determination may be made whether data associated with the particular entry of the virtual cache memory is dirty. If the data associated with the particular entry of the virtual cache memory is dirty, then a write back operation may be initiated, and data in the particular entry of the virtual cache memory may be written to memory. A command may then be issued that indicates that the virtual cache memory and the memory locations of the memory access operation are cohered, and the memory access operation may be completed. A determination also may be made whether the memory access operation is a write operation. If the memory access operation is a write operation, then the particular entry of the virtual cache memory may be invalidated. The virtual cache memory may be included in a single chip microprocessor, and a device external to the single chip microprocessor may initiate the memory access operation. A circuit that bridges between the external device and an internal bus may receive a command from the external device to initiate the memory access operation.

摘要： A process for producing a Monascus pigment by growing a microorganism of the genus Monascus in an aqueous nutrient medium under aerobic conditions. The microorganism is grown at a pH-value in the range from 4 to 7 in a first medium which promotes its growth; a first biomass is obtained; the first biomass thus obtained is transferred to a second medium which stimulates the production of pigment; the pH is adjusted to a value in the range from 2 to 4; the growth process is continued for a period of 2 to 7 days at a temperature in the range from 20.degree. to 35.degree. C. and pigment is extracted with a solvent from the second biomass obtained.
