摘要： A memory bandwidth control device for improving efficiency of data transfer between an external device and a memory. A memory is used for temporarily storing and outputting data to be communicated with external devices being connected via input/output ports, and an I/O buffer dynamically assigns memory bandwidth to external devices requesting data transfer when receiving the data transfer requests from the external devices to the memory. When compared to assigning fixed memory bandwidth, efficiency of data transfer to the memory can be significantly improved without wasting memory bandwidth.

摘要： A blade for an axial fluid machine comprises an effective blade portion having a root portion and a tip portion and projecting blade portions. The projecting blade portions are defined by axis reference lines extending to an upstream side with respect to a fluid flow from at least one of the root portion and the tip portion of the effective blade portion and by axes obliquely extending from ends of the axis reference lines toward a leading edge of the effective blade portion. The projecting blade portions are formed continuously to and integrally with the leading edge of the effective blade portion so that the effective blade portion and the projecting blade portions have substantially the same maximum blade thickness.
