The method comprises the following steps of, l, obtaining a traveling wave solution of the first cycle; 2, expanding expressions of the traveling wave solutions to any cycle; and, 3, calculating the traveling wave energy and the rate of change thereof. According to the method, vibration displacement and energy change of the rope equipment under the fixed—damping boundary condition can be accurately obtained, so that a proper damping value is selected, the purpose of vibration damping by the rope equipment is achieved, the advantages of accurate calculation and high efficiency are achieved, and the design cycle of vibration damping design of the moving rope equipment can be greatly shortened.

Apparatus and method for burst mode data storage

An apparatus and a method are disclosed, in the apparatus, a memory management unit includes: a first cache unit, adapted to store a plurality of first source operands and one first write address; a second cache unit, adapted to store at least one pair of a second source operand and a second destination address; a write cache module, adapted to discriminate between destination addresses of a plurality of store instructions, so as to store, in the first cache unit, a plurality of source operands corresponding to consecutive destination addresses, and to store, in the second cache unit, non-consecutive destination addresses and source operands corresponding to the non-consecutive destination addresses, where the first write address is an. initial address of the consecutive destination addresses; and a bus transmission module, adapted to transmit the plurality of first source operands and the first write address in the first cache unit to a. memory through a bus in a write burst transmission mode. In embodiments of the present invention, a burst transmission mode is established between a processor and the bus. This can help reduce occupation of bus address bandwidth and accelerate write efficiency of the memory.
