a set of software or hardware which takes sets of bits, representing pixels, and combines them with other sets of bits in a variety of different ways
                                                            
                                                     
                        
                                                
                        
                        
                            a special-purpose chip or hardware system used for fast implementations of bitmapped graphics
                                                            
                                                     
                        
                                                
                        
                        
                            Blitter (from BLIT or Block Image Transfer) is a co-processor chip dedicated to memory data transfers, usually independently of the CPU using bit blit methods.
