    • An information processing system which reduces an access latency from a memory read request of a processor to a response thereto and also prevents reduction of the effective performance of a system bus caused by an increase in the access latency. In the information processing system, a memory controller is connected with the processor via a first bus and connected with a memory via a second bus, and a buffer memory is provided in the memory controller. The control circuit is controlled, before a memory access from the processor is carried out, to estimate an address to be possibly next accessed on the basis of addresses accessed in the past and to prefetch into the buffer memory, data stored in an address area continuous to the address and having a data size of twice or more an access unit of the processor.
    • 一种信息处理系统,其将访问延迟从处理器的存储器读取请求减少到对其的响应,并且还防止由于访问等待时间的增加而导致的系统总线的有效性能的降低。 在信息处理系统中,存储器控制器经由第一总线与处理器连接,并经由第二总线与存储器连接,并且在存储器控制器中提供缓冲存储器。 在执行来自处理器的存储器访问之前,控制电路被控制以基于过去访问的地址来估计可能下一次被访问的地址并预取到缓冲存储器中,存储在连续的地址区域中的数据 并且具有处理器的访问单元的两倍或更多的数据大小。

    • A resource distribution method capable of lending surplus resources among a plurality of services and reducing the maintenance cost of the surplus resources is provided. Computer resources in the standby system have a dead standby state in which at least an application is not installed. A plurality of services or a plurality of users share the computer resources in the standby system. As a result, improvement of the utilization factor of idle computer resources and server integration are implemented, and the cost required to maintain the computer resources is reduced. Furthermore, load prediction is conducted as regards individual services by using past operation history. Idle computer resources secured from services having surplus and maintained are thrown in according to a result of the prediction.
