Abstract: A data collision avoidance circuit is utilized in a memory write control circuit of an image signal processing apparatus for preventing the write and read clocks of a FIFO memory from colliding. The circuit contains a write enable signal generating unit, a window pulse section set up unit, and a write enable signal control unit. The write enable signal generating unit generates a write enable signal in response to the write control odd/even field signal to write the data into the FIFO memory. The window pulse section set up unit generates a window pulse signal having a predetermined pulse width. The time interval of the predetermined pulse width is designed to be greater than a time interval during which write and read clocks of the FIFO memory can potentially collide, and the window pulse signal is generated in response to a read control odd/even field signal.
