Patent US 4,144,566

A parallel processor having a large number of elementary processors connected in parallel to an address bus and a control bus. Each elementary processor contains a memory and control and processing circuits to perform calculations on bits addressed in the memory and bits coming either from this memory or from a peripheral unit. Each elementary processor further contains a small capacity fast memory and the control and processing circuit contains a single storage flip-flop able to perform calculations in series on the bits extracted from the memories and/or coming from the peripheral unit. All the fast memories are parallel connected.
