Synchronous FIFO Controller

The FIFO controller manages a circular buffer of depth G_FIFO_DEPTH. A write advances the pointer when the FIFO is not full, and a read advances the pointer when it is not empty. Outputs expose empty/full status, read and write pointers, and the occupancy level.

Reset is synchronous and active-high.

• Writes are ignored when the FIFO is full
• Reads are ignored when the FIFO is empty

Generics:

• G_FIFO_PTR_WIDTH : integer - Pointer width
• G_FIFO_DEPTH : integer - FIFO depth
