Patent number: 8914764Abstract: A dynamic system coupled with “pre-Silicon” design methodologies and “post-Silicon” current optimizing programming methodologies to improve and optimize current delivery into a chip, which is limited by the physical properties of the connections (e.g., Controlled Collapse Chip Connection or C4s). The mechanism consists of measuring or estimating power consumption at a certain granularity within a chip, converting the power information into C4 current information using a method, and triggering throttling mechanisms (including token based throttling) where applicable to limit the current delivery per C4 beyond pre-established limits or periods. Design aids are used to allocate C4s throughout the chip based on the current delivery requirements. The system coupled with design and programming methodologies improve and optimize current delivery is extendable to connections across layers in a multilayer 3D chip stack.Type: GrantFiled: June 18, 2012Date of Patent: December 16, 2014Assignee: International Business Machines CorporationInventors: Pradip Bose, Alper Buyuktosunoglu, John A.

Patent number: 8826216Abstract: A system and method of operating an integrated circuit (IC) having a fixed layout of one or more blocks having one or more current sources therein that draw electrical current from a power source. The method includes dynamically issuing to a block configured to perform operations responsive to an instruction received at the block, a reserve amount of tokens; determining for each issuance of instruction to the block whether that block's reserve token amount exceeds zero; and one of: issuing the instruction to the block if the token reserve for that block is greater than one, and decrementing, after issuance of the instruction, by one token the block's reserve token amount, or, preventing issuance of an instruction to the block. In the method, each block may be initialized to have: a reserve token amount of zero, a token expiration period; a token generation cycle and a token generation amount.Type: GrantFiled: June 18, 2012Date of Patent: September 2, 2014Assignee: International Business Machines CorporationInventors: Pradip Bose, Alper Buyuktosunoglu, John A.

Patent number: 7168009Abstract: Disclosed are a method and system for analyzing a computer program. The method comprises the steps of analyzing the program to generate an initial error report and a list of suspected error conditions, and generating a set of assertions and inserting the assertions into the program to determine if the suspected error conditions are valid. Preferably, a strong static analysis method is used to identify an initial set of error reports. When this analysis fails to determine if the condition is true or false, the condition along with the potential program error is captured to form a suspected error. Suspected errors are directed to an assertion generator to produce a monitor—that is, source code modification that is integrated with the original program. This and other inserted monitors check the conditions for the suspected error during the program execution.Type: GrantFiled: September 24, 2003Date of Patent: January 23, 2007Assignee: International Business Machines CorporationInventors: John A.

Patent number: 7089542Abstract: A method and apparatus are provided for analyzing software programs. The invention combines data flow analysis and symbolic execution with a new constraint solver to create a more efficient and accurate static software analysis tool. The disclosed constraint solver combines rewrite rules with arithmetic constraint solving to provide a constraint solver that is efficient, flexible and capable of satisfactorily expressing semantics and handling arithmetic constraints. The disclosed constraint solver comprises a number of data structures to remember existing range, equivalence and inequality constraints and incrementally add new constraints. The constraint solver returns an inconsistent indication only if the range constraints, equivalence constraints, and inequality constraints are mutually inconsistent.Type: GrantFiled: December 13, 2002Date of Patent: August 8, 2006Assignee: International Business Machines CorporationInventors: Daniel Brand, John A.

Patent number: 4703435Abstract: Logic is synthesized from a flowchart-level description by first generating an AND/OR logic design, simplifying the AND/OR logic, converting the AND/OR logic to NAND or NOR logic, applying particular sequences of simplifying transformations to the NAND or NOR logic, converting the simplified NAND or NOR logic to a target technology, and simplifying the target technology where possible. The end result is an interconnection of primitives of the target technology in a language from which automated logic diagrams can be produced.Type: GrantFiled: July 16, 1984Date of Patent: October 27, 1987Assignee: International Business Machines CorporationInventors: John A.
