A flexible input/output (I/O) interface allows a processing core to communicate high-speed data with a several different types of interfaces including a Direct Memory Access (DMA) interface and a streaming interface. The I/O interface includes a streaming interface for transferring streamed data from the streaming data bus to the core-processing engine, a DMA interface for transferring DMA data from the DMA data bus to the core-processing engine, and an arbiter for coordinating data transfer with the core-processing engine between the streaming interface and DMA interface. The arbiter may operate in a split-bus-mode wherein the arbiter performs the address phase for more than one channel prior to entering into the data phase. The flexible I/O interface may include a common address bus and data bus between the processing engine and the interfaces. Alternatively, a switching fabric may couple separate address and data buss of the interfaces with the processing engine.
An input/output (I/O) system that transfers control and data between a core-processing engine and a plurality of bus types including direct memory access (DMA) bus and a streaming data bus, the system comprising:
An arbiter for coordinating data communications between a plurality of interfaces and a processing core comprising:
A method of transferring control and data between a core-processing engine and a plurality of bus types including direct memory access (DMA) bus and a streaming data bus, the method comprising:
