Abstract:

In the case of laptops and tablet PCs that replace desktop, it uses the Windows operating system to provide various functions depending on operating system dependency, the Windows operating system does not support real-time processing because it uses multilevel feedback queue scheduling that extends round-robin scheduling. Also, since the initial value of Local APIC Counter cannot be obtained from the Windows 8, the realtime processing function provided through the existing RTiK does not work. Therefore, in this paper, we calculate Local APIC Counter value by using MSR_FSB_FREQ register to support real-time processing function on tablet PC's. We designed and implemented RTiK+, which provides real-time processing function to guarantee the periodicity by calculating the operation time of accurate timer. In order to verify and evaluate the performance of the implemented the RTiK+, the period was measured by using the Read Time-Stamp Counter (RDTSC) instruction and it was confirmed that it operates normally at 1ms and 0.1ms period.
