Title: Innovations of George M O'Har
Introduction
George M O'Har is a notable inventor based in Chelmsford, MA (US). He holds two patents that showcase his contributions to the field of computing and memory management. His work has significantly impacted the design and functionality of arithmetic logic units and memory addressing systems.
Latest Patents
One of O'Har's latest patents is for an arithmetic logic unit with outputs indicating invalid computation. This invention discloses an apparatus that utilizes a programmable read-only memory (PROM) to perform arithmetic functions for an associated processor. The PROM serves as a look-up table for computation results, where operands used in mathematical computations form an address to the PROM. This allows for reading out the computation results stored within. Additionally, the PROM contains information bits that indicate whether the computation result is valid or invalid. These bits are stored in flip-flops to inform the processor of the validity of the computation result.
Another significant patent by O'Har is for a nibble and word addressable memory arrangement. This apparatus addresses memory by word and by one of several nibbles within a word. It allows for the incrementing or decrementing of nibble and word addresses, enabling access to adjacent nibbles and words without generating new addresses. An initial word address is placed in an address counter, while an initial nibble address is placed in a nibble control. The two addresses indicate a specific nibble within a particular word, and subsequent increment or decrement signals adjust these addresses accordingly.
