<P>PROBLEM TO BE SOLVED: To obtain the estimation of a step execution time by expressing a behavior at an application level by an event-driven simulation and statistically approximating memory access timings of a smaller granularity. <P>SOLUTION: A memory access detection module 316 in a referenced integrated system 310 detects an access of an application 312 to memory of a platform 314. A measurement module 330 puts data, which is detected by the memory access detection module 316 and whose beginning and end are delimited by a beginning/end-of-step detection module 318, into a form of an execution trace, and transfers it to a modeling/simulation system 320. A calculation module 324 estimates values such as an execution time and memory band usage rate using the data received from the measurement module 330. <P>COPYRIGHT: (C)2012,JPO&INPIT |
