Abstract: In a computer system, when data for a register assigned to a current process arrives at a processing element, an instruction for loading this data is automatically inserted into an instruction sequence to be fetched by an instruction fetch unit provided in the processing element, thus synchronizing of data on registers is enabled. In addition, when data for a register assigned to a process which had previously been suspended and is not the current process arrives at the processing element, the data is written to a corresponding save area allotted in local memory for that register. Suspension of a process occurs at a point in time at which a register assigned to that process is accessed by an instruction but no data is yet present in the register and when this process suspension occurs, the process to be executed is switched to another process.

Abstract: A method and an apparatus for sorting chromosomes or cells by utilizing a difference in fluorescent profilepatterns. A linear laser beam having a high beam intensity is formed from several fringe patterns, and fluorescence intensities from local portions of chromosome or cell are measured in real-time. Resolution of chromosome or cell is improved. A type of flowing chromosome or cell which permits the rotational conditions within a range can be sorted accurately and rapidly.

Abstract: In order to discriminate minute particles such as biological particles or organic polymers, a suspension of minute particles is formed into a particle stream with the individual particles substantially separated from each other, the particle stream is irradiated with a high-intensity light beam, the particle stream irradiated with the high-intensity light beam is formed into droplets, and the particle in each droplet is discriminated in accordance with the intensity of light emited from the particle upon irradiation with the high-intensity light beam. In discriminating the particles, a high-intensity light pulse is used as the high-intensity light beam, and each minute particle is discriminated in accordance with a change in the emitted light intensity over a period of time.
