ABSTRACT:
A computer apparatus having a unique architecture which is capable of both forward and reverse execution modes. The reverse execution mode is implemented at the machine language level, and relies on an internal stack in micromemory or the microprocessor's stack pointer register for data saving purposes. A unique instruction set design is employed which includes a plurality of forward execution instructions and complementary reverse execution instructions of opposite sense. During the reverse execution mode, the reverse execution instructions are implemented in a logical flow which is substantially the reverse of that used during the forward execution mode.
