Title: Douglas Beard: Innovator in Address Translation Technology
Introduction
Douglas Beard is a notable inventor based in Allen, TX (US), recognized for his contributions to address translation technology. He holds 2 patents that showcase his innovative approach to systems and methods for virtual addressing.
Latest Patents
His latest patents include "Address translation unit employing programmable page size" and "Address translation unit employing a victim TLB." The first patent discloses systems and methods for virtual addressing that utilize an address translation unit with variable page size. This is achieved by employing direct, victim, and programmable block translation lookaside buffers. The selective comparisons between contents on a linear address bus and linear address tags are controlled by a size mask register, which further manages a multiplexer to steer bits onto a physical address bus from either the linear address bus or a physical address register. The second patent introduces an address translation unit that employs a direct-mapped translation lookaside buffer along with a relatively small, associative victim translation lookaside buffer. This invention translates linear addresses to physical addresses efficiently while avoiding thrashing, all without requiring large amounts of hardware and space.
