'
Two new DLion instructions to consider':'
'
	 an instruction that will multiply two 3 x 3'
	  floating-point matrices (useful for doing'
	  two-dimensional homogeneous coordinate'
	  transformations).'
'
	 another one for doing 4 x 4 matrix multiplication'
	   (for 3-D homogeneous coordinate'
	   transformations).'
'
The addition of these two instructions, along with the creation of some higher-level driver software, could turn the DLion into quite a good performer in the graphics arena.'
