Latest Patents

One of his latest patents is titled "Error reporting network in multiprocessor computer." This invention introduces a high-performance, high-reliable backplane bus with a simple configuration and operation. The error reporting network (ERN) provides an economical method for collecting the error state of an entire system in a uniform and consistent manner. This uniformity simplifies interface software and standardizes hardware handling of various error classes. In a preferred embodiment, serial error registers are utilized, which minimizes implementation costs and eases the software interface to these registers. The design ensures that serial error information is transmitted over a separate data path from the main parallel bus, reducing the risk of original errors corrupting the error information. Each CPU is equipped with a local copy of the complete error information, which enhances redundancy and minimizes the impact of potential CPU failures, allowing for coordinated error recovery.

Another significant patent by Kayfes is "System and method to initialize registers with an EEPROM stored boot sequence." This invention describes a method for initializing registers using configuration records read from an EEPROM connected to an ASIC during system reset. The configuration records specify which target registers to configure and the data to be written. These records are translated into register write requests, and the data is sent to the target registers via the ASIC's bus. During this initialization process, other masters, such as processors, may be blocked from accessing the registers, ensuring a smooth setup.
