  • Computer system high speed link method and means
    Patent number: 5218677
    Abstract: This embodiment provides apparatus and method for implementing a High Speed Link (HSL) such as the newly proposed ANSI High Performance Parallel Interface (HIPPI) standard on processors complexes like the IBM 3090 having a paging store with an independent bus. A high speed link adapter (HSLA) including input and output buffers and controls is coupled to the independent bus under program control. Program access to high speed link is obtained by an extension to the Page-in and Page-out instructions.

  • Fast two-level dynamic address translation method and means
    Patent number: 4695950
    Abstract: A unique high-speed hardware arrangement for generating double-level address translations in combination a translation look-aside buffer (TLB) structure that can store and lookup intermediate translations during a double-level translation. The hardware proceeds to the completion of a double-level translation without having to backup its operation, although an intermediate TLB miss is encountered, without danger of CPU deadlock occurring. The hardware arrangement also performs all single-level address translations required by the system.
