Abstract
To generate sequential addresses when multiple integrated circuit (IC) devices are accessing the same memory, an address token is sent along the IC devices communicatively coupled in a ring topology. The address token is first transferred along the ring topology during a memory reservation phase in which each IC device can set a corresponding memory request bit to indicate that the IC device has data to write to the memory. The modified address token is then transferred along the ring topology again during a memory access phase. During the memory access phase, each IC device that has data to write can perform a memory write operation using a sequential address determined from the contents of the address token.
