The Stream Buffer Controller is designed for AMD and Intel FPGAs, acting as a bridge between stream and memory-mapped DMA with support for up to 16 independent streams. It facilitates data buffering in an external memory with up to 4 GB capacity, providing versatile FIFO-like capability. Each stream operates through configurable memory, utilizing AMBA AXI4-Stream interfaces for streamlined communication between embedded CPUs, FPGAs, or controllers.
