DRAFT: A dynamically reconfigurable processor for integer arithmetic

A special computer for high-precision arithmetic features an ALU that is dynamically reconfigurable under program control. The 256-bit ALU consists of 8 32-Mt slices each of which has its own ALU operation code in each microinstruction. The slices can remain logically separated from each other, or he dynamically connected to either or both of their neighbors under control of a segment control code that is part of each microinstruction. The micro-assembly language designed for the machine includes special features to assist in the control of the segmentation, data addressing, and control sequencing. Estimations of the times required to execute arithmetic operations on the machine show that it will be exceptionally fast for problems in computational number theory and factoring of integers.
