Title: Innovations of John A. Celio
Introduction
John A. Celio is a notable inventor based in San Diego, CA. He has made significant contributions to the field of computer technology, holding a total of 3 patents. His work focuses on enhancing memory management systems and improving computer interface apparatuses.
Latest Patents
One of his latest patents is for a "High speed memory management system and method." This invention involves fetching a virtual address and its corresponding access protection code simultaneously from secondary memory. These elements are stored in first and second content addressable memories. When a program-generated virtual address is applied to the first memory, the corresponding access code is applied to the second memory. The match signals obtained from both memories are combined to produce an access control signal, which regulates access to data stored at a real memory address.
Another significant patent is for a "Computer interface apparatus using split-cycle lookahead addressing." This apparatus minimizes performance degradation due to address translation in computer systems that utilize random access memory and paging. It translates initial addresses into real addresses using addressable memory and substitute paging. The invention decreases access time by avoiding the translation of virtual address bits that are also real address bits, allowing memory access to commence using available real address bits.
