Memory controller with graphic processing function

A method for use in a memory control device, the method comprising:

• receiving at least one selection signal and size/address information from a master;
• and
• performing a graphic process based on the at least one selection signal and size/address information.

A downsampling unit comprising:

• data accumulation logic configured to receive texture data from a master or a memory interface to add texture data based on a downsampling ratio;
• and
• a divider configured to divide the added texture data received from the data accumulation logic to calculate an average value.

A mipmap generating unit comprising:

• a graphic processing control unit configured to receive sizes and addresses of original textures to calculate sizes and addresses of sub-textures;
• and
• a memory writing control unit configured to receive the addresses of the sub-textures from the graphic processing control unit to provide the addresses of the sub-textures to a memory interface and select a time to purge the memory interface.
