Stream Buffer Controller
The Stream Buffer Controller IP Core is optimized for Intel (Altera) and Xilinx FPGAs and 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 GB 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 in terms of operation mode, buffer size and buffer address for each stream. The configuration is done over a memory mapped slave interface, either by an embedded-CPU, by a FPGA Manager application or by an application specific stream configurator controller in VHDL.
