Abstract: A central processing unit which includes an arithmetic and logic unit, local store registers and general registers, allows for the use of the arithmetic and logic unit for housekeeping purposes such as address modification during portions of a machine cycle. The processing unit contains no counters or compare circuits other than the single arithmetic and logic unit with all data flow being through the arithmetic and logic unit.
