Supported Device Family:
The Stream Buffer Controller IP Core implements a versatile Stream to Memory Mapped DMA bridge with 16 independent streams. The IP core allows data buffering in an external memory device to provide virtual FIFO capability with up to 4 GByte memory size. It provides AMBA AXI4-Stream interfaces for each write and read data stream. A common memory-mapped master interface (AXI or Avalon) is provided to access the external memory device over an interconnect. The IP core is highly configurable and supports four different operation modes for each channel:
•\tFIFO mode: writing and reading to the memory is done over the AXI4-Stream interfaces
•\tWrite mode: Writing to the memory is done over the AXI4-Stream, Reading from the memory is done by a CPU.
•\tRead mode: Writing to the memory is done by a CPU, reading from the memory is done over the AXI4-Stream interface.
•\tROM mode: Reading from the memory is done over the AXI4-Stream interface. The memory must be initially written by a CPU
Data width conversion to/from any byte-multiple width
Supports up to 16 write and read streams (depending on product options)
Configurable status flags for write and read path
Available with Avalon or AMBA-AXI interface
