Patent EP-0381447-A2 (EP)
Inventor: HETHERINGTON RICKY C
IPC: G06F12/08
Filed: 1990-01-30
Abstract: In the field of high speed computers it is common for a central processing unit to reference memory locations via a virtual addressing scheme, rather than by the actual physical memory addresses. In a multi-tasking environment, this virtual addressing scheme reduces the possibility of different programs accessing the same physical memory location. Thus, to maintain computer processing speed, a high speed translation buffer 30 is employed to perform the necessary virtual-to-physical conversions for memory reference instructions. A translation buffer fixup unit 52 is employed to update the translation buffer 30 with the most recently accessed physical memory locations. Therefore, subsequent virtual memory references to these same locations are quickly processed without reference to the much slower main memory 14. The translation buffer fixup unit 52 consists of a state machine 66 controlling hardware specifically designed for the purpose of updating the translation buffer 30. These translation buffer updates are performed immediately after a "miss" is detected by stalling the translation buffer 30 to prevent subsequent conversions until the update is completed.

Abstract: A recording and reproducing device, which records and reproduces information on and from a rewritable recording medium having absolute addresses and comprising an information recording area wherein information entered from external devices is recorded and a TOC area wherein additional information with respect to the information recorded in the information recording area is recorded, comprises: an optical head and an electromagnet for recording information in the information recording area, and for recording in the TOC area the absolute addresses indicating at least the recording positions of information as additional information every time the information is recorded in the information recording area; a display section for graphically displaying the recorded and unrecorded ranges of the information recording area independently according to the absolute addresses recorded in the TOC area with respect to the recording positions of each piece of information; warning means for warning to show that a position has already been occupied by referring to the additional information recorded in the TOC area when it is instructed to record new information in the position of the information recording area where another information has already been recorded; first editing means for erasing the additional information from   the TOC area with respect to any information within the information recording area when the information is completely erased therefrom; and second editing means for detecting a remaining amount of any information when the information is partially erased from the information recording area, for recording in the TOC area absolute addresses indicating the recording positions of the remaining information part in the TOC area, after replacing the absolute addresses indicating the recording positions of its original information with those indicating the recording positions of the remaining information part when the remaining amount is not less than a predetermined value, and for erasing the additional information of the partially erased information from the TOC area when the remaining amount of the partially erased information is less than the predetermined value. With the arrangement, even if the stored additional information is lost due to the cut-off of the power source, in the recording operation thereafter, the user can accurately recognize the recording conditions of the information recording area, and such trouble as to record another information overlapping with information already recorded is perfectly prevented, and further the user can recognize space domains easily and accurately.

Abstract: In a multiprocessor computer system, a number of processors are coupled to main memory by a shared memory bus, and one or more of the processors have a two level direct mapped cache memory. When any one processor updates data in a shared portion of the address space, a cache check request signal is transmitted on the shared data bus, which enables all the cache memories to update their contents if necessary. Since both caches are direct mapped, each line of data stored in the first cache is also stored in one of the blocks in the second cache. Each cache has control logic for determining when a specified address location is stored in one of its lines or blocks. To avoid spurious accesses to the first level cache when a cache check is performed, the second cache has a special table which stores a pointer for each line in said first cache array. This pointer denotes the block in the second cache which stores the same data as is stored in the corresponding line of the first cache. When the control logic of the second cache indicates that the specified address for a cache check is located in the second cache, a lookup circuit compares the pointer in the special table which corresponds to the specified address with a subset of the bits of the specified address. If the two match, then the specified address is located in the first cache, and the first cache is updated.

Abstract: A laser system includes three or more narrow-gap laser discharge channels mounted radially about a common axis. The laser discharge volumes may be excited by RF radiation, microwave radiation or by means of the MAGPIE system. The laser discharge channels may be mounted in an optical resonator having a common unstable cavity mode, a toric resonator, with or without feedback, or a retro-reflected toric unstable resonator. A pair of adjacent discharge channels may be coupled to form a ring microwave resonator, and the ring resonator may be formed by a continuous double ridged waveguide. Excitation for the continuous double ridged waveguide is optimally produced by a magnetron. The approach, when applied to a very large number of radial discharge channels, provides an efficient and inexpensive means for constructing an extremely high powered gas laser in a very small physical package.

Abstract: 1. Method and circuit for automatic fine frequency tuning with high precision. 2.1 Known analog automatic frequency fine-tuning systems are imprecise and, for example due to a required oscillating circuit, not totally integrable. Known digital automatic frequency fine-tuning systems may offer high precision, but require a comparatively large chip surface and increased power consumption. 2.2 For the purposes of high-precision fine frequency tuning, e.g. to a specific television channel, an adjustable-frequency analog circuit, e.g. an FM demodulator, is adjusted in an integrated circuit with the aid of a control current. The control current generated in a control loop is dependent on a precision corresponding to a reference frequency and on a reference capacity integrated in the chip. Following a frequency selection, the analog circuit is calibrated and the frequency is then fine-tuned in a measurement mode. The analog circuit then operates in normal mode. 2.3 Analog circuit for automatic fine frequency tuning with high precision. <IMAGE>

Abstract: In order to investigate particles in a fluid, a flow cell (1) causes the fluid to flow past a sensor (16) which receives light from a continuous light emission system (76). When the sensor (16) detects a change in light, a particle detector (35) is triggered, which in turn triggers a pulse generator (34) and hence an intermittent light emission system (75). Light then illuminates the flow cell (1) to allow a CCD camera (15) to photograph the particle. The photographs taken by the CCD camera (15) are analyzed by an image processor (32). In order to obtain an accurate particle concentration measurement, it is necessary to modify the initial concentration measurement derived from the analysis of particle images by the image processor by a compensation coefficient. This operation is carried out by a concentration compensator (39). The result may then be displayed (38). Additional analysis may be carried out by changing the magnification of the CCD camera (15), or by selecting for analysis only those particles of a selected size or type.
