    • A performance analyzing method for an information processing system includes a logic called “hardware monitor” for CPU performance profiling, CPU performance information collectable by the monitor, a CPU performance information collecting program to collect the information, transaction performance information collectable by an application program, and a calculation procedure to calculate performance analysis information such as a dynamic step count using the CPU performance information and the transaction performance information. Therefore, the performance analysis information can be collected while reducing the operation to count the number of source code lines of an application program or the operation to obtain the execution count of each macro code.
    • 用于信息处理系统的性能分析方法包括用于CPU性能分析的CPU硬件监视器,由监视器收集的CPU性能信息,用于收集信息的CPU性能信息收集程序,应用程序可收集的事务性能信息, 以及使用CPU性能信息和交易性能信息来计算诸如动态步数的性能分析信息的计算过程。 因此,可以收集性能分析信息,同时减少对应用程序的源代码行的数量的操作或者获得每个宏代码的执行计数的操作。

    • Decrease in throughput performance called a “jamming” in a memory device is prevented. There is provided a timing generation part which gives, based on a request signal outputted for each unit of the data processing from a data processing part, an output timing for a burst transfer request to a burst transfer request generation part. Based on the relationship in size between a lapsed time from the output of the burst transfer request to the activation of the request signal and a time specified by a set threshold value of a threshold value register, the timing generation part controls output timing for a burst transfer request. When the lapsed time exceeds the time specified by a maximum threshold value, the burst transfer request generation part is given an output timing for the burst transfer request without waiting for the activation of the request signal. As a result, when the issuance of the request signal is delayed, a next burst transfer request can be given to the memory device without waiting for the issuance but preceding it.
    • 防止在存储器件中称为“干扰”的吞吐量性能降低。 提供了一种定时生成部件,其基于从数据处理部分对每个单位的数据处理输出的请求信号,向突发传送请求生成部分提供突发传送请求的输出定时。 基于从突发传送请求的输出到请求信号的激活的经过时间与由阈值寄存器的设定阈值指定的时间之间的大小关系,定时生成部控制突发的输出定时 转移请求。 当经过的时间超过由最大阈值指定的时间时,突发传送请求生成部分被给予突发传送请求的输出定时,而不等待激活请求信号。 结果,当请求信号的发出被延迟时,可以向存储设备提供下一个突发传送请求,而不必等待发出,而在其之前。
