Abstract: A cooling structure for a motorcycle transmission includes a heat dissipation fan disposed inside a transmission housing, an inner wall of the transmission housing is provided with a flow-guiding groove directly opposite to the heat dissipation fan and a labyrinth partition adjacent to a rear side of the flow-guiding groove, an air inlet communicating with the flow-guiding groove is formed in a side wall of a front end of the flow-guiding groove, a groove bottom of the flow-guiding groove is provided with an arc-shaped flow-guiding slope, a head end of the flow-guiding slope is located at the air inlet, the flow-guiding slope is gradually inclined toward a direction close to the heat dissipation fan from the head end to a tail end, and a lower end of the labyrinth partition is spaced from a bottom edge of the transmission housing to form an air passing opening.

Abstract: A address translation circuit includes: a frequency division circuit, configured to receive a first address increment signal with a first frequency, process the first address increment signal, and output a second address increment signal with a second frequency as well as a jump signal with the second frequency, where the jump signal is used to indicate a first address jumping among the N memory banks; an address counter, configured to receive the second address increment signal and output an address count signal; and a row address increment circuit, configured to output a first row address increment signal when the address count signal indicates that column address counting has been finished, and the jump signal indicates a last memory bank group.
