Abstract: This invention provides a data processing system capable of performing an interrupt exception handling routine as many times as the number of times of occurrence of a request event for the same interrupt exception handling routine if the request event occurs a plurality of times. A software interrupt counter or a hardware interrupt counter for retaining the number of times of occurrence of an interrupt request generation event counts up when a software processing which generates a software interrupt or a hardware event that generates a hardware interrupt occurs, and counts down when a CPU performs a processing for removing the interrupt request. If the value of the software interrupt counter and the value of the hardware interrupt counter are not zero, a software interrupt request signal and a hardware interrupt request signal to the CPU are asserted.

Abstract: A useful semiconductor processing device (LSI) is capable of implementing the precise setting of signals at the final stage of user system development and enabling the user to build a logic circuit in the device in a very short time. The LSI includes a CPU, a flash memory which is a nonvolatile memory, a programmable logic which is a SRAM-type field programmable gate array, and a configuration circuit which implements the logic circuit configuration operation. At the event of power-on reset, logic building data stored in the flash memory is transferred to the programmable logic to establish a logic circuit in it under control of the configuration circuit, so that the logic circuit built in the programmable logic can be used immediately after the power-on reset of the device.

Abstract: In accordance with a preferred embodiment of this invention, a fiber reinforced polyester article having a low surface profile is produced from a material which may be used either as a bulk molding or as a sheet molding compound. Preferably, this composition is produced from a formulation comprising about equal proportions of (1) an unsaturated polyester condensation product dissolved in (2) a copolymerizable reactive diluent solution of from proportionally 11/2 to 2 parts by weight of tertiary butyl styrene per each part of styrene. This formulation will of course also contain a filler such as a particulate calcium carbonate and reinforcing glass fibers. It is the specific combination of styrene and tertiary butyl styrene which promotes the low profile surface in the final molded article.
