Title: The Innovations of Robert E. Vogelsberg
Introduction
Robert E. Vogelsberg is a notable inventor based in Boulder, CO (US). He has made significant contributions to the field of technology, particularly in the area of Direct Memory Access (DMA) devices. With a total of 5 patents to his name, Vogelsberg's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is titled "Chained DMA devices for crossing common buses." This invention involves chaining or cascading two or more DMA devices to perform DMA transfers across common buses. The modified DMA devices act as a bus slave relative to another DMA bus master device, allowing information to be transferred from one bus to another across a third bus common to the DMA devices. The slave DMA can also cause the master DMA to stop sending data, which helps limit the bandwidth requirements of the common bus. Another significant patent is "Fast memory power-on diagnostics using DMA." This innovation allows memory testing to be performed by a dedicated hardware system, initialized by a system processor. It employs the processor's DMA capability, enabling the system to execute other programs without waiting for memory testing to complete. The same hardware can also function as a memory scrubber.
