摘要： Execution of the read-ahead function to fragmented data will result only in caching non-contiguous physical blocks, failing to hit and wasting any read-ahead data. Even if file accesses are sequential, but if intervals between accesses are too long, it may occur that any cached data are discharged from the buffer memory due to another readout operation with any cached data ending up in vain. Information concerning fragmented locations is taken out from the input-output circuit and included in the management data of the file system. Predefined management data is added to the readout command of the interface. This management data is used to determine whether or not read-ahead should be activated, the amount of data to be read ahead, and other controls for read-ahead processing. With reference to random access or time-based access to the files, the application is to designate whether or not the read-ahead function should be used so as to enable the storage unit to carry out efficient accesses.
摘要翻译：将预读功能执行到分段数据将仅导致缓存非连续的物理块，不能击中并浪费任何预读数据。即使文件访问是顺序的，但是如果访问之间的间隔太长，则可能会发生任何高速缓存的数据从缓冲存储器中释放出来，这是由于任何缓存数据的另一次读出操作无效。关于分段位置的信息从输入输出电路中取出并包含在文件系统的管理数据中。预定义的管理数据被添加到接口的读出命令中。该管理数据用于确定是否应激活预读，预读数据量以及其它用于预读处理的控件。参考对文件的随机访问或基于时间的访问，应用程序是指定是否应该使用预读功能，以使得存储单元能够执行有效的访问。

摘要： It is difficult to implement an arrangement for handling of contents data such as moving picture and audio data because of a need to ensure the desired bit rate, etc. In ordinary cases, therefore, a configuration dependent on hardware results and the portability of the system is low. A layered contents processing architecture improves the portability of the system and facilitates the development of application programs. In a case where part of devices are combined into an LSI, the layered architecture can also be applied to the LSI.
摘要翻译：由于需要确保期望的比特率等，因此难以实现用于处理诸如运动图像和音频数据的内容数据的布置。因此，通常情况下，依赖于硬件结果的配置和系统的可移植性低。分层内容处理架构提高了系统的可移植性，并有助于开发应用程序。在将部分器件组合成LSI的情况下，分层结构也可以应用于LSI。

摘要： Complete data deletion from a storage device imposes high loads respectively on a host computer for transfer of insignificant data and on a storage device for execution of data transfer, a write operation, and a retry process. As such, a complete deletion command is provided to control deletion of a specified area of a storage space of the storage device without requiring data transfer from the host computer to the storage device. The complete deletion command on the storage device is executed in a simple manner that a write operation is performed to write “arbitrary data” over data of an area specified in, for example, a delete command, by a controller of the storage device, whereby the complete deletion of the specified data is executed. Consequently, a file system is enhanced to enable an application to execute the complete deletion command (“complete file data detection function”).
摘要翻译：存储设备的完整数据删除在主计算机上分别施加高负载以传送无关紧要的数据，并在存储设备上执行数据传输，写入操作和重试过程。因此，提供完整的删除命令来控制存储设备的存储空间的指定区域的删除，而不需要从主机到存储设备的数据传输。存储装置上的完全删除命令以简单的方式执行，即通过存储装置的控制器执行写入操作以对例如删除命令中指定的区域的数据写入“任意数据”，由此执行指定数据的完全删除。因此，增强文件系统以使应用程序能够执行完整的删除命令（“完整的文件数据检测功能”）。
