Abstract: Apparatus and methods for facilitating data movement among circuit blocks are disclosed. In certain embodiments, dataflow gaskets with circular buffers are deployed in any number or arrangement to achieve efficient on-chip data movement among different circuit blocks of the die. Each dataflow gasket can be attached to a corresponding circuit block using tightly coupled memories to provide low latency and fast access to incoming and outgoing data streams. Furthermore, memory allocation and buffer management can be handled by the internal logic in the dataflow gasket to reduce or eliminate software development efforts. For example, the dataflow gasket can use circular buffers to allow the circuit block to access the dataflow gasket's memories without needing to understand the internal memory addressing of the dataflow gasket.

Abstract: Apparatus and methods for facilitating data movement among circuit blocks are disclosed. In certain embodiments, an integrated circuit (IC) includes a network of dataflow gaskets including a first dataflow gasket coupled to a first circuit block and a second dataflow gasket coupled to a second circuit block. The first circuit block can write to the second circuit block by programming output stream registers of the first dataflow gasket for an outgoing write stream that includes a header identifying the second dataflow gasket. The header can be provided by the first dataflow gasket to the second dataflow gasket over the network, and in response to the header reaching the second dataflow gasket, the second dataflow gasket can program the input stream registers of the second dataflow gasket for an incoming read stream.
