Patent number: 7269126Abstract: A method for constructing orthogonal codes of length N for use in a network utilizing quasi-synchronous code division multiple access combined with time division duplexing. The method determines the balanced vectors of length N, being all possible cross-correlation vectors resulting from zero cross-correlation of codes of length N. An arbitrary code of length N is utilized, and a bitwise XOR-ing is performed with all the balanced vectors to produce a set of codes with which the arbitrary code is orthogonal. A bitwise XOR-ing of the original balanced vectors is performed and the code is added to a set of orthogonal codes if the result of the bitwise XOR-ing of the original balanced vectors is balanced. The method is repeated until the set of orthogonal codes is complete.Type: GrantFiled: September 15, 2003Date of Patent: September 11, 2007Assignee: Agilent Technologies, Inc.Inventors: Jan Mennekens, Carl Mertens, Lieven Philips, Jurgen Vandermot, Jan Vanhoof

Patent number: 6681387Abstract: Disclosed is a method and apparatus for detecting and monitoring program hot spots during execution that may be implemented in hardware. A hot spot detector tracks branch instructions which are retired. Frequently executed branch instruction addresses within a particular interval are designated as hot spot candidates. A hot spot detection counter is used to track non-hot spot branches and hot spot candidate branches. When hot spot candidate branches are frequently encountered compared to non-hot spot candidate branches, the hot spot detector may notify the operating system and hot spot candidate branch addresses may be supplied to a runtime optimizing compiler and a monitor table or a hot spot monitor. The hot spot monitor may disable the hot spot detector when a program is operating in known hot spots and may enable the hot spot detector if the program has strayed from known hot spots.Type: GrantFiled: March 8, 2000Date of Patent: January 20, 2004Assignee: Board of Trustees of the University of IllinoisInventors: Wen-mei William Hwu, Matthew Carl Merten, Andrew Raymond Trick, Christopher Neith George, John Christopher Gyllenhaal
