Abstract
Systems and methods are disclosed for reducing or eliminating address lines that need to be routed to multiple related embedded memory blocks. In particular, one or more inputs are added to a block RAM such that when one or more of the inputs are asserted, the address input to the Block RAM may be incremented prior to being used to retrieve data contents of the block RAM. Thus, if address <addr> is provided to the block RAM and the address increment signal is asserted, data may be read from location <addr+N> instead of <addr>, where N may be an integer. Block RAMs with such address arithmetic may be used to implement wide First-In-First-Out (FIFO) queues, wide memories, and/or data-burst accessible block RAMs.
