Abstract
An embodiment of the present invention is directed to a method of deterministic collision detection involving at least two ports. The method includes receiving a read/write operation at a first data rate at a first port of a multi-port device, receiving a read/write operation at a second data rate at a second port of the multi-port device, detecting a collision between the first port and the second port if a same address space is accessed by the first port and the second port coincidentally, asserting a busy signal at least one of said first port and said second port a number of clock cycles after detecting said collision, storing an address location of said address space in a memory register, and deterministically report the collision using the address location and the number of clock cycles.
