Latest Patents

Heller's latest patents showcase his ingenuity in managing address translations in computing environments. One of his key inventions describes a "Mechanism for control of address translation by a program." This innovation allows a program operating in one address space to access data or invoke another program in a different address space without the need for a supervisory intervention. Each address space is assigned an Address Space Number (ASN), facilitating an organized set of address translation tables. Heller's approach utilizes a program changeable space selection control bit to manage two distinct sets of these tables, significantly improving cross-space program interactions.

Another notable patent is aimed at providing an "Authorization mechanism for establishing addressability to information," which further supports efficient inter-program communication. This mechanism works similarly, permitting one program to access another's data space under strict authorization conditions, enhancing security and functionality within complex software environments.
