Abstract:
A program response time estimating apparatus, wherein the response time calculation unit performs the estimation based on the following equation: (1-mEm&it;â€ƒ&it;A)&it;t-m&it;â€ƒ&it;Em&it;â€ƒ&it;A&it;&ee;-y/m&it;â€ƒ&it;D&it;{(y+2&it;â€ƒ&it;m&it;â€ƒ&it;D)&it;(1-&ee;t/m&it;â€ƒ&it;D)+t&it;â€ƒ&it;&ee;t/m&it;â€ƒ&it;D}=x(1)and the response time of the estimation-undergoing program can be calculated through the following equation (2): t+mEm&it;â€ƒ&it;A&it;{m&it;â€ƒ&it;D-(m&it;â€ƒ&it;D+y)&it;&ee;-y/m&it;â€ƒ&it;D},(2)wherein t represents the solution of expression (1), mA represents the background program average arrival interval, mE represents the background program average execution time, mD represents the background program average relative cutoff time, x represents the estimation-undergoing program execution time and y represents the relative cutoff time of the estimation-undergoing program.
