Domain Modeling and the Duration Calculus: International by Alan Burns, Andy Wellings (auth.), Chris W. George, Zhiming

By Alan Burns, Andy Wellings (auth.), Chris W. George, Zhiming Liu, Jim Woodcock (eds.)

This ebook offers completely revised instructional papers in line with lectures given by means of major researchers on the overseas education tuition on area Modeling and the length Calculus, held in Shanghai, China, in September 2007 as an linked occasion of ICTAC 2007, the 4th foreign Colloquium on Theoretical points of Computing.

The 4 instructional papers provided supply useful insurance of software program defense, area modeling of software program engineering, and length calculus for genuine time platforms - originating from lectures of best specialists in those fields from Europe and Asia. themes addressed intimately are: improvement of real-time structures, area engineering utilizing summary modeling, the realm of length calculus, and formal tools like language description utilizing the operational semantics approach.

A slight rearrangement of these conditions shows a single hit if Ri + J ∈ [0, T), a double hit if Ri + J ∈ [T, 2T) and so on. This can be represented in the same form as the previous response time equations as follows [4]: Ri = Bi + Ci + j∈hp(i) R i + Jj Cj Tj (10) In general, periodic processes do not suffer release jitter. An implementation may, however, restrict the granularity of the system timer (which releases periodic processes). In this situation, a periodic process may also suffer release jitter.

As long as all the values (Ts, Cs and so on) are in the same units from the same time band, the tests can be applied. So in these (and later examples), the unit of time is just considered to be a tick of some notional time base. Table 4 contains three processes that have been allocated priorities via the rate monotonic algorithm (hence process c has the highest priority and process a the Delivering Real-Time Behaviour 23 Table 4. 33 Process a b c 0 10 20 30 40 50 60 Time Process release time Executing Process completion time – deadline met Preempted Deadline missed Fig.

Wni Cj Tj (5) The set of values is, clearly, monotonically non-decreasing. When wni = wn+1 , the solution to the equation has been found. If w0i < Ri then wni i is the smallest solution and hence is the value required. If the equation does not have a solution then the w values will continue to rise (this will occur for a low-priority process if the full set has a utilization greater than 100%). Once they get bigger than the process’s period, T, it can be assumed that the process will not meet its deadline.
