Patent number: 8898503Abstract: Transferring data from a first clock domain to a second clock domain, wherein the second clock domain has a fixed clock frequency, and the first clock domain has a variable clock frequency. The first clock domain and the second clock domain operate in a synchronous mode when the variable clock frequency is equal to the fixed clock frequency, and in an asynchronous mode when the variable frequency is lower than the fixed frequency. A first buffer and a second buffer are used for a data transfer from the first clock domain to the second clock domain. The second clock domain comprises a multiplexor connected to the first buffer and the second buffer. The multiplexor forwards data from the first buffer further into the second clock domain in the synchronous mode and from the second buffer into the second clock domain in the asynchronous mode.Type: GrantFiled: November 7, 2013Date of Patent: November 25, 2014Assignee: International Business Machines CorporationInventors: Daniel M.

Patent number: 8868960Abstract: A computer system is provided which includes a plurality of nodes, which include chips of different types. In each node, one of the chips is configured as a master chip, which is connected to one or more slave chips via two or more multi-drop nets (e.g., checkstop, clockrun). The master chip and the slave chips are connected to a reference clock, and event triggering information is transmitted via the multi-drop nets (checkstop, clockrun) to the slave chips. Event trigger commands are submitted by the master chip when it receives a request, and internal offset counters are used to adjust both the receiving cycle and the cycle when the command is propagated to the units on the chips. In operation, the offset counters are synchronized by a reference clock.Type: GrantFiled: June 28, 2011Date of Patent: October 21, 2014Assignee: International Business Machines CorporationInventors: Tobias Bergmann, Ralf Ludewig, Tobias Webel, Ulrich Weiss

Patent number: 8332787Abstract: A method includes removing a code segment from a hardware description language design to create a modified hardware description language design. The code segment represents at least one time sensitive path in the hardware description language design. The method includes creating a delta list of differences between the modified hardware description language design and a physical hardware representation that is logically equivalent to the hardware description language design. The method includes extracting a portion of the physical hardware representation that corresponds to the time sensitive path based, at least in part, on the delta list. The method also includes creating a structured hardware description language design of the time sensitive path using the extracted portion of the physical hardware representation, wherein the structured hardware description language design comprises structural information of the extracted portion of the physical hardware representation.Type: GrantFiled: November 5, 2010Date of Patent: December 11, 2012Assignee: International Business Machines CorporationInventors: Friedhelm Kessler, Thomas M.
