Abstract: A hard/soft cooperative verifying simulator is based on a SystemC simulator, and provides the capability of reducing overhead of context switching control thereby to shorten processing time. Time keepers for controlling simulation times of a plurality of threads are provided corresponding to the threads generated as simulation models for hardware and software. Each of the time keepers has a variable which holds a simulation time for each thread, a variable which holds a summation time, and a break request queue which stores a break time and its corresponding break method therein. The time keeper manages both variables and the queue in response to six types of method invocations from the thread, and invokes a wait function of the SystemC simulator when necessary. It is thus possible to reduce the number of times that a wait function invocation is performed, and shorten the entire processing time.

Abstract: A method of calibration of a particle characterization apparatus, and a particle characterization apparatus, in which particles suspended in a liquid are passed through an orifice one by one for characterization of the particles, for instance by Coulter counting. The calibration does not require utilization of special calibration particles or liquids. A priori knowledge of the shape of a typical size distribution of a blood sample is utilized to adjust the apparatus based on an initial relatively short counting period of the sample in question. The initially determined size distribution is compared to the corresponding known typical size distribution and the apparatus is subsequently adjusted to counteract possible differences. Upon adjustment of the apparatus, the remaining part of the sample is passed through the orifice for determination of the actual particle size distribution of the remaining sample.
