Latest Patents

One of Rothman's latest patents is titled "Calling instructions for a data processing system." This invention involves a digital data processing system with a central processor that responds to diverse instructions, including those for calling subroutines. When the central processor executes a calling instruction, it saves information corresponding to the operating environment for the calling routine. This information is then utilized in the subroutine to establish the operating environment for the subroutine. A common return instruction at the completion of each subroutine allows the central processor to retrieve the saved operating information, thereby reestablishing the operating environment for the calling routine.

Another significant patent is for a "Central processor unit for executing instructions with a special operand." This invention features a digital data processing system with a central processor that responds to diverse instructions characterized by variable length. Each instruction includes an operation code, and certain instructions also include one or more operand specifiers. The control circuitry in the central processor decodes the operation code and each operand specifier byte in succession. This process combines the operand specifiers and information derived from the operation code to obtain the address from which the operand is to be retrieved or to which an operand is to be transferred.
