  • Patent number: 10468149
    Abstract: Extreme ultraviolet mirrors and masks used in lithography and methods for manufacturing an extreme ultraviolet mirror or mask. Initial data is obtained that includes materials and optical properties for a first intermixed layer, a second intermixed layer, a first pure layer, and a second pure layer in each of a plurality of periods of a multi-layer stack for an optical element. For multiple thicknesses for the first pure layer and multiple thicknesses for the second pure layer, a reflectivity of the multi-layer stack is determined based on the initial data, a thickness received for the first intermixed layer, and a thickness received for the second intermixed layer. One of the thicknesses for the first pure layer and one of the thicknesses for the second pure layer are selected that maximize the reflectivity of the multi-layer stack.

  • Publication number: 20190332540
    Abstract: Various techniques are directed to a storage management method, an electronic device and a computer readable medium. Such techniques may involve: receiving a request for a target storage block in a disk; obtaining, from a cache, a cache indicator indicating a state of a group of storage blocks including the target storage block, the number of bits occupied by the cache indicator in the cache being less than the number of storage blocks in the group of storage blocks; and responding to the request based on the cache indicator. Such techniques can reduce times of access to the disk and thereby enhancing input/output performance.

  • Publication number: 20190335189
    Abstract: Systems, apparatuses, and methods for reducing latency when consuming an encoded video bitstream in real-time are disclosed. A video encoder encodes a video bitstream and writes chunks of the encoded bitstream to a bitstream buffer. Prior to the encoder completing the encoding of an entire frame, or an entire slice of a frame, a consumer module consumes encoded chunks of the bitstream. In one implementation, to enable pipelining of the consumption with the encoding, the encoder updates a buffer write pointer with an indication of the amount of data that has been written to the bitstream buffer. The consumer module retrieves encoded data from the bitstream buffer up to the location indicated by the buffer write pointer. In this way, the consumer module is able to access and consume encoded video data prior to the encoder finishing encoding an entire frame or an entire slice of the frame.

  • Publication number: 20190332287
    Abstract: Techniques manage a storage system. The techniques involve: in response to a first control unit of the storage system receiving an access request to a target storage area in the storage system, determining whether the target storage area is located in a first storage area or a second storage area; in response to the target storage area being located in the second set of storage areas, determining that a second control unit of the storage system processes the access request, the first control unit and the second control unit sharing the storage system; and updating an access state of the first control unit to the target storage area, the access state indicating access permission for the target storage area included in the first control unit. Such techniques can effectively reduce the number of CMI messages related to a stripe lock mechanism in a dual active SP.

  • Publication number: 20190327744
    Abstract: A first access network device determines a timing offset of a first carrier and a second carrier. The timing offset is an offset between timing of downlink communication of the first carrier and timing of uplink communication of the second carrier. The first carrier is a carrier using a first radio access technology (RAT), and the second carrier is an uplink frequency division duplex (FDD) carrier using the first RAT and a second RAT. The first access network device sends first indication information to a terminal. The first indication information indicates the timing offset, and the timing offset is used to determine the timing of the second carrier. Based on this scheme, the terminal can use a shared frequency band resource of LTE, thereby improving resource utilization.
