Appl. No.:

09/303211

Inventors:

Patrick E. Perry - Shelburne VT
Sebastian T. Ventrone - South Burlington VT

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G01R 3128

US Classification:

714727, 714729, 714731

Abstract:

A system and method for determining the operational state of a logic device having a plurality of shadow registers, each associated with one of a plurality of functional registers. Data stored in a functional register is, under selected conditions, also stored in an associated shadow register. These conditions include without limitation receipt by the functional register of predetermined event information such as an opcode, memory address or other information. Data in a given set of functional registers, e. g. , registers making up pipeline stages in a microprocessor, may be stored in shadow registers simultaneously or sequentially when given data reaches a given register in the set. Additionally, data is stored in the shadow registers without interrupting execution cycles of the logic device.

International Classification:

G06F 1100

US Classification:

714704, 370311

Abstract:

A way of dynamically modifying error recovery on a communications controller to operate at the lowest power mode allowed by current error rate conditions. When operating conditions are good and a small number of errors are detected, a low power error detection/correction mode is entered saving battery life. The low power error correction mechanism runs at a slower frequency and lower power than the high power mechanism and maintains the same data rate for the controller, thus saving power. Selecting the controller error (power) mode may be externally, such as by a person using a control dial on a cellular telephone when the voice data gets too noisy. Alternatively, the selection can be automatic, a critical error level detector internally making the selection.

International Classification:

G06F009/45

US Classification:

712248, 712213, 712229, 712227, 717131, 717161

Abstract:

Processor overhead is reduced and processor performance, particularly processing speed and power savings, is improved, allowing real-time processor restarts, by skipping operational codes (opcodes) singly or in groups in accordance with one or more execution bits set during post-processing in opcodes preceding opcodes to be skipped. Thus portions of an application program which consume excessive power or are unsupported in particular operating environments can be easily and selectively de-activate while maintaining the integrity of the applications program. Local or cache memory is also effectively expanded and processor performance improved by eliminating opcodes from local or cache memory which will not be called.

Filed:

May 17, 2006

Appl. No.:

11/383786

Inventors:

Patrick E. Perry - Shelburne VT, US

International Classification:

G01C 21/34

US Classification:

701209, 701202, 34099519

Abstract:

Disclosed herein is a method of route planning for global positioning system (GPS) based navigation systems. The method identifies route segments used in a GPS based navigation system and records an actual historical time of travel for at least one route segment traveled by users of the GPS based navigation system travel. The actual historical time of travel comprises the amount of time taken by a user of the GPS based navigation system to go from a beginning of the route segment to an end of the route segment. With embodiments herein, the day and time that the route segment was recorded is also noted. Then, the actual historical time of travel and the day and time for the route segment can be stored in a database. This information can be stored for a single-user or can be combined from a plurality users of the GPS based navigation systems.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1300

US Classification:

395280

Abstract:

Disclosed is a tristate circuit driver capable of both parking the output in a deasserted state and switching to a tristate mode in less than one clock cycle. In a preferred embodiment, the driver circuitry utilized a delay device to generate a pulse signal immediately after the transition in an enable signal is detected. The pulse signal then causes the tristate driver to output a signal of a predetermined voltage for a duration of less then one clock cycle.

Abstract:

A low powering apparatus for automatic reduction of power in active and standby modes is disclosed. The low powering apparatus includes a state detector, a margins of safety device and a positioning device. The state detector detects a first or second state, such as a standby state and an active state, that has predominated in a recent past. The margins of safety device indicates safe low power margins in correlation to the detected first or second state. The positioning device adjusts the power level according to the outputs of the state detector and margins of safety device. Thus, the low powering apparatus minimizes the power level of a system at the first or second state without compromising full performance of the system.
