Title: Innovations of Donald D Harenberg
Introduction
Donald D Harenberg is a notable inventor based in Placentia, California. He holds three patents that showcase his contributions to the field of computer engineering. His work primarily focuses on enhancing system development and debugging processes within computer processors.
Latest Patents
One of Harenberg's latest patents is the On-chip Debug Port. This invention provides circuitry that enables system development within an inaccessible computer processor. The debug port is integrated within the internal logic of a single-chip, reduced instruction set signal processor. It consists of five functional elements: the debug bus unit (DBU), debug command unit (DCU), debug instruction unit (DIU), debug inject/extract unit (DJU), and debug flow unit (DFU). Each element plays a crucial role in buffering data, executing commands, inserting instructions, injecting external information, and monitoring program execution.
Another significant patent is the Branch Decision Encoding Scheme. This invention addresses the limitations of a dedicated debug port on a single-chip computer processor. It allows for the monitoring of a 24-bit program counter through an 8-bit data interface by compressing the data during real-time program development. By focusing on specific discontinuities in the program counter, Harenberg's invention enables efficient data output while maintaining synchronization.
