   Description: This module creates a 2k x 8 ROM that is used for video character generation.
			The ROM contents are also defined in the CHAR_GEN_ROM.ucf file.

			The charcter generator defines a 8 x 8 block of pixels used for ASCII characters,
			line graphics and Xilinx logo. The least significant 3 address bits define the line
			within the character block and the most significant 8 bits define the specific character.
			
			If the user wishes to extend the character set then the "INIT_20 - INIT_3F" values must be
			defined.

Code 	  00h  	defines a solid block
Codes 01h-04h	defines the Xilinx logo
Codes 05h-1Fh	defines line graphics		
Codes 20h-7Fh 	defines the ASCII characters
Codes 80h-FFh  	user defined characters

	Conventions:
		All external port signals are UPPER CASE.
		All internal signals are LOWER CASE and are active HIGH.
