Abstract: A translation table apparatus used to perform both forward and backward bitmap vector translations. The translation table is used with bit vectors where it is desired to displace one or more bits to different bit positions in accordance with a configurable bitmap translation table. The translation of one bit vector to another is performed in real time and any number of bits can be moved simultaneously. In addition, both the bit vectors and the contents of the translation table can be changed on the fly. Translations are performed on multiple bits simultaneously wherein several bits can be displaced at the same time in accordance with the translation table. The same hardware used to implement the translation table is used for backward translations as well.
