    • A method and apparatus for cached adaptive transforms for compressing data streams, computing similarity, and recognizing patterns have been disclosed.In one embodiment of the invention an encoder and decoder begin with a baseline transform. As data is transferred an algorithm is arranged so that the encoder and decoder adapt toward a superior basis than the baseline, with a corresponding reduction in the encoding bit rate. That is the algorithm adapts to the incoming data stream and can use a custom basis. We deliberately avoid having to send the custom basis itself (when possible), because sending the basis vectors consumes precious bandwidth and may defeat the goal of compression. The encoder and decoder can bootstrap themselves into using one or more better bases.In one embodiment of the invention there is no beginning baseline transform shared between the encoder and the decoder.
    • 已经公开了用于压缩数据流的缓存自适应变换的方法和装置,计算相似度和识别模式。 在本发明的一个实施例中,编码器和解码器以基线变换开始。 随着数据的传输,算法被安排使得编码器和解码器适应于比基线更优越的基础,并且编码比特率相应地减小。 这是算法适应输入的数据流,并可以使用定制的基础。 我们故意避免必须发送自定义基础(如果可能),因为发送基本向量会消耗宝贵的带宽,并可能会破坏压缩的目标。 编码器和解码器可以引导自己使用一个或多个更好的基础。 在本发明的一个实施例中,在编码器和解码器之间没有共享的开始基线变换。

    • A storage controller facilitating extending storage capacity while suppressing investment related to storage capacity is provided. System configuration information, including content of a definition of a virtual volume having a storage capacity that is larger than a real storage capacity including the storage capacity of a storage device unit, and content of a definition of at least one of a real volume formed by dividing the real storage capacity, and a pool area, is stored. Based on the system configuration information, relevant data is written to or read from an address position in the storage device unit in response to a data input/output request from the host system designating an address in the real volume, and data is written to or read from the pool area in response to a data input/output request from the host system designating an address in the virtual volume other than the real volume.
    • 提供了一种便于扩展存储容量的存储控制器,同时抑制与存储容量有关的投资。 系统配置信息,包括具有大于包括存储设备单元的存储容量的实际存储容量的存储容量的虚拟卷的定义的内容,以及由存储设备单元的存储容量中的至少一个定义的内容,以及由 存储实际存储容量和池区域。 基于系统配置信息,响应于来自主机系统的指定实际卷中的地址的数据输入/输出请求,相关数据被写入或从存储设备单元中的地址位置读取,并且数据被写入或 从池区域读取响应来自主机系统的数据输入/输出请求,指定除了实际卷之外的虚拟卷中的地址。
