Latest Patents

Fumiaki Abe holds a patent for a technique that controls channel operations in a host computer. This patent, which is categorized under a method and apparatus, focuses on updating a dynamically alterable channel program that manages input/output (I/O) devices. The technique is designed to emulate a guest computer system that utilizes dynamic address translation (DAT) in an I/O channel sub-system. By implementing this technique, channel throughput is significantly increased, thereby reducing performance degradation that may occur due to the absence of channel DAT on the host system. The method relies on program controlled interrupt (PCI) chaining and employs 'just-in-time' translation for each new virtual channel program segment generated by a guest operating system.
