The Stream Buffer Controller is a versatile IP core optimized for AMD and Intel FPGA architectures, designed to facilitate communication between stream data and memory-mapped interfaces via DMA. It allows for data buffering on external memory, providing virtual FIFO capabilities with a capacity of up to 4 GB. The core efficiently manages up to 16 streams, each configurable in terms of operation modes and buffer sizes, which enhances flexibility across diverse applications.
The IP core operates in various modes including FIFO, write, read, and ROM, which accommodate a wide range of needs in data handling. Special emphasis is placed on easy configuration via a memory-mapped slave interface using an embedded CPU or a dedicated FPGA controller, offering versatility in integration and operation without the need for additional CPUs.
Noteworthy features include the support for AMBA AXI4-Stream interfaces, enabling seamless integration with existing communication infrastructures. Additionally, it offers conversion for data width in read and write streams and vendor-independent implementation options for collaboration across different systems. This IP core is particularly valuable for applications in data acquisition, image processing, and real-time data management, making it a critical component in modern processing systems.
