 * Last Revised: 2008/08/01
 *
 * This file is created as the new top level entity of
 * Memory Controller IP Core, which is nothing
 * but a wrapper of mc_top with some port names changed.
 * The reason of doing so is because identifiers in the
 * format of "xxx_" are not supported in VHDL,
 * but are valid in Verilog. So we have to use the wrapper
 * to make MC can be used in higher level VHDL entities.
