Latest Patents:

John H Rowan's notable patent is for the Modular Programmable Signal Processor. This system's innovative modular architecture enables the utilization of a selected number of arithmetic element (AE) units with a single arithmetic element controller (AEC) unit, thus allowing effortless expansion or contraction of computational ability. The AE units perform similar calculations under the control of the AEC unit, responding to common address control and coefficient signals. Each AE unit has its own extended work store (EWS) unit, synchronized with the AE unit, which enables continuous and high-speed computations. The EWS units also connect to an external interface unit, allowing data transfer when not being accessed by the AEC unit. Moreover, the AE units can perform parallel calculations by utilizing the multiplier output data from a single multiplier and storage unit matched to several register and arithmetic logic (RALU) units, significantly enhancing calculation speed.
