Virtual FIFO, the smart way
The Stream Buffer Controller IP Core is optimized for FPGAs and implements a versatile Stream to Memory Mapped DMA bridge with up to 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 an AMBA AXI4-Stream interface for each write and read data stream. A common memory-mapped master interface (AXI4 or Avalon) is provided to access the external memory device.
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, an FPGA Manager application or an application-specific stream configurator controller in VHDL.
