Title: Dale E. Folwell: Innovator in Debugging Technology
Introduction
Dale E. Folwell is a notable inventor based in Placentia, California, recognized for his contributions to debugging technology. With a total of six patents to his name, Folwell has made significant advancements in the field of computer processors.
Latest Patents
Among his latest patents is the "On-chip debug port," which provides essential circuitry for enabling system development within an inaccessible computer processor. This invention incorporates a debug port within the internal logic of a single-chip, reduced instruction set signal processor. The debug port consists of five interacting 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). The DBU buffers data from the signal processor and allows for off-chip connections. The DCU decodes and executes debug commands, while the DIU inserts instructions into the instruction stream. The DJU injects external information into the signal processor, and the DFU monitors program execution.
Another significant patent is the "Branch decision encoding scheme," which addresses the limitations of a dedicated debug port on a single-chip computer processor. This invention allows for the compression of 24-bit data to be output through an 8-bit port in real time. By monitoring specific discontinuities in the program counter, such as branches and jumps, the invention enables efficient data handling during program development.
