Abstract
Apparatus for shifting the output of a bit matrix character generator ninety degrees to provide ninety degrees shifted characters and comprises a barrel shifter for barrel shifting bit slices of the bit matrix characters coupled to a linear array shifter for linear array shifting the information that was first barrel shifted. A feedback loop which includes a rotate RAM memory having its output connected to the input of the barrel shifter means to twice barrel shift the information which was previously barrel shifted and then linear array shifted to provide a bit matrix character output which is rotated ninety degrees from the original bit matrix character provided at the output of the character generator.
