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.
摘要（中）：
仲裁器检测持有直接存储器访问（DMA）请求的N个缓冲器的等待状态，并检测核心R通道DMA存储器的R核心通道的可用性。 仲裁器基于检测，动态地授予N个缓冲区的R访问R核心通道的权限。 N到R控制器将来自N个缓冲器的DMA请求传送到当前授予的R个核心信道中的一个，并且将N个缓冲器中的每一个保存在不同的R个核心信道中的不同数据的位置记录。
