Title: The Innovations of Steven Wallach
Introduction
Steven Wallach is a notable inventor based in Framingham, MA (US). He has made significant contributions to the field of data processing systems, holding a total of 4 patents. His work has advanced the way logical addresses are handled in computing systems.
Latest Patents
One of Wallach's latest patents is titled "Data processing system having a unique address translation unit." This invention describes a data processing system that manages thirty-two bit logical addresses derived from both sixteen bit and thirty-two bit logical addresses. The system features a unique translation mechanism for converting these logical addresses into physical addresses. It includes decoding means for macro-instructions from both basic and extended instruction sets, which contain specific bit patterns to identify the type of instruction to be decoded. The decoded macro-instructions lead to micro-instructions, which are sequenced by a unique micro-instruction sequencing unit. The system employs hierarchical memory storage with eight segments, allowing controlled access based on privilege levels.
Another significant patent by Wallach is "Data processing system having instruction responsive apparatus for both." This invention also deals with thirty-two bit logical addresses and includes means for decoding macro-instructions. The instruction responsive apparatus responds to unique microinstructions that facilitate various operations, such as selecting interrupt routines, loading segment identification registers, and performing arithmetic operations.
