摘要：
An arbiter detects waiting states of N buffers holding direct memory access (DMA) requests, and detects an availability of R core channels of a core R-channel DMA memory. The arbiter, based on the detection, dynamically grants up to R of the N buffers access to the R core channels. An N-to-R controller communicates DMA requests from the N buffers to currently granted ones of the R core channels, and maintains a location record of different data from each of the N buffers being written into different ones of the R core channels.
