Stream Buffer Controller
Features
- The IP Core supports four different operation modes for each channel:
- FIFO mode: writing and reading to the memory is done over the AXI4-Stream interfaces
- Write mode: Writing to the memory is done over the AXI4-Stream, Reading from the memory is done by a CPU.
- Read mode: Writing to the memory is done by a CPU, reading from the memory is done over the AXI4-Stream interface.
- ROM mode: Reading from the memory is done over the AXI4-Stream interface. The memory must be initially written by a CPU
- Supports up to 16 write and read streams (depending on product options)
- Configurable status flags for write and read path
- Vendor-independent implementation
- Available with Avalon or AMBA-AXI interface
- Data width conversion to/from any byte-multiple width
Benefits
- Supports data width conversion for the write and read data streams
- The use of different operation modes provides the implementation of versatile applications with a single IP core.
- Easy integration thanks to the unified bus interface and the clearly laid out register bank
- A stand-alone solution without the need of a CPU can be easily realized by a stream configuration controller that is provided in VHDL
