Abstract: A neural processing unit (NPU) is described. The NPU includes an NPU direct memory access (NDMA) core. The NDMA core includes a read engine having a read buffer. The NDMA core also includes a write engine having a write buffer. The NPU also includes a controller. The controller is configured to direct the NDMA core to perform hardware memory bandwidth optimization for reading/writing NDMA data in the read buffer and/or NDMA data in the write buffer. The NDMA core is also configured to transparently combine NDMA transaction requests for a data stripe to increase local access to available tensors in artificial neural networks.

Abstract: A system for data decompression may include a processor coupled to a remote memory having a remote dictionary stored thereon and coupled to a decompression logic having a local memory with a local dictionary. The processor may decompress data during execution by accessing the local dictionary, and if necessary, the remote dictionary.

Abstract translation: 用于数据解压缩的系统可以包括耦合到具有存储在其上的远程字典的远程存储器的处理器，并且耦合到具有本地字典的本地存储器的解压缩逻辑。 处理器可以在执行期间通过访问本地字典来解压缩数据，并且如果需要，可以对远程字典进行解压缩。
