摘要： The invention provides a method improving flexibility of at least one direct memory access (DMA) channel. The at least one DMA channel is used by a plurality of DMA engines of a first device to direct data transmission between the plurality of DMA engines of the first device and a second device. An explanatory embodiment of the method comprises: allowing any of a plurality of DMA engines to use any of the at least one DMA channels, and enabling some of the plurality of DMA engines to share a target channel if some of the plurality of DMA engines simultaneously compete for the target channel, one of the at least one DMA channel.

摘要： A signal display apparatus has a plurality of shift registers and a selecting circuit. The shift registers receives a first clock and the selecting circuit receives a selecting signal from a data flow according to a second clock, and output enabling signals to the shift registers according to the selecting signal. The shift registers selectively store data in the data flow according to the first clock in response to the enabling signals. The signal display apparatus and the method for storing data are capable of reducing the transfer time for a serial data single series signal to overcome the prior art shortcomings.
