| 20090079460 | SYSTEMS AND METHOD FOR MEASURING NEGATIVE BIAS THERMAL INSTABILITY WITH A RING OSCILLATOR - An integrated circuit, in accordance with one embodiment of the present invention, includes a first device under test (DUT), a first ring oscillator, a second DUT and a second ring oscillator. The first DUT is biased such that interface traps are generated during a first mode. The generated interface traps result in a decrease in a first drive current of the first DUT. The second device under test is biased to maintain a reference drive current during the first mode. The operating frequency of the first ring oscillator, during a second mode, is a function of the first drive current. The operating frequency of the second ring oscillator, during the second mode, is a function of the reference drive current. The integrated circuit may also include a comparator for generating an output signal as a function of a difference between the operating frequency of the first and second ring oscillator. | 03-26-2009 |
| 20090045846 | ADVANCED REPEATER WITH DUTY CYCLE ADJUSTMENT - An advanced repeater with duty cycle adjustment. In accordance with a first embodiment of the present invention, an advanced repeater includes an output stage for driving an output signal line responsive to an input signal and a plurality of active devices for selectably adjusting a duty cycle of the signal. The advanced repeater may further include circuitry for producing a delayed version of the signal. | 02-19-2009 |
| 20080313440 | SWITCHING TO ORIGINAL CODE COMPARISON OF MODIFIABLE CODE FOR TRANSLATED CODE VALIDITY WHEN FREQUENCY OF DETECTING MEMORY OVERWRITES EXCEEDS THRESHOLD - A method of translating instructions from a target instruction set to a host instruction set. In one embodiment, a plurality of first target instructions is translated into a plurality of first host instructions. After the translation, it is determined whether the plurality of first target instructions has changed. A copy of a second plurality of target instructions is stored and compared with the plurality of first target instructions if the determining slows the operation of the computer system. After comparing, the plurality of first host instructions is invalidated if there is a mismatch. According to one embodiment, the storing, the comparing and the invaliding is initiated when the determining indicates that a page contains at least one change to the plurality of first target instructions. In one embodiment, the determining is by examining a bit indicator associated with a memory location of the plurality of first target instructions. | 12-18-2008 |
| 20080303600 | Dynamic Ring Oscillators - A dynamic oscillating ring circuit is described, which has multiple non-inverting domino circuits, each having a signal input, a trigger input, inputs for charge state clock and clocked cutoff and an output inverter. A number of the domino circuits are coupled in series, the output of one feeding the input of the next, to form a chain, which form stages of the ring. A number of the stages are coupled in series, the output of one feeding the input of the next, to form the ring. The first domino circuit of said chain receives a logic signal input and a single trigger input for the chain. Within the ring, the output of each stage feeds the input signal to the next stage and is fed back to clock an earlier stage to allow the ring to oscillate. | 12-11-2008 |
| 20080294868 | SYSTEM AND METHOD FOR IDENTIFYING TLB ENTRIES ASSOCIATED WITH A PHYSICAL ADDRESS OF A SPECIFIED RANGE - A system and method for identifying a TLB entry having a physical address that is within a specified range are disclosed. The method includes obtaining a tentative TLB entry from a page table entry and accessing a physical address associated with the tentative TLB entry. The method further includes comparing the physical address of the tentative TLB entry with a predetermined range of addresses. If the physical address is within the finite range of addresses, an exception is invoked. In response to the exception, the physical address and/or an attribute of the tentative TLB entry can be modified. The tentative TLB entry can then be stored in a TLB. | 11-27-2008 |
| 20080246110 | STRUCTURE FOR SPANNING GAP IN BODY-BIAS VOLTAGE ROUTING STRUCTURE - Structures for spanning gap in body-bias voltage routing structure. In an embodiment, a structure is comprised of at least one metal wire. | 10-09-2008 |
| 20080218215 | Advanced Repeater Utilizing Signal Distribution Delay - An advanced repeater utilizing signal distribution delay. In accordance with a first embodiment of the present invention, such an advanced repeater circuit comprises an output stage for driving an output signal line responsive to an input signal and a feedback loop coupled to said output signal line for changing state of said output stage subsequent to a delay after a transition of said output signal. The delay is due to transmission line effects of said output signal line. | 09-11-2008 |
