Latest Patents

Kimmens' latest patents include a unique process for loading a microcode control store in a data processing system. This technique involves starting up a data processing system where a 'basic' or 'kernel' instruction set is stored in an auxiliary store and transferred to the processor's control store during the start-up phase. The kernel instruction set is utilized to execute an initialization program that identifies an I/O device containing a microcode local program and a desired microcode file. Notably, no microcode load program is transferred to the processor's main memory. Instead, using the kernel instructions, the desired microcode file is transferred in selected blocks from the I/O device to the main memory and subsequently to the microcode control store. The microinstructions from the desired microcode file can then be employed to load the appropriate operating system software, preparing the overall processor for various applications.

Another significant patent by Kimmens is a method and apparatus for enhancing the operation of a data processing system. This system features separate kernel, vertical, and horizontal microcode, along with separate loading of vertical microcode and a permanently resident kernel microcode. It also includes a soft console with dual levels of capability, a processor with dual ALC and microcode processors, and an instruction processor. Additionally, the system incorporates a multifunction processor memory, a malfunction nibble shifter, and a high-speed look-aside memory control.
