Fifo buffers
WebMar 30, 2024 · The FIFO module is a variable-length buffer with scalable register word-width and address space, or depth. There are watermark flags available for “almost full” and “almost empty” conditions. The depth of the “almost full” and “almost empty” flags can be adjusted within the module’s parametrization, or generic block in the ... WebDec 4, 2016 · A circular buffer often uses RAM with cycling address to indicate start and end pointers with flow control to prevent overlap or buffer overflow/underflow exceeding the buffer size, or going beyond empty. A FIFO is a linear buffer, managed by status on empty, full with almost empty/full for faster flow control on high speed data.
