The process compares the previous proxy results for a known, public Internet address to the previous proxy results for the desired Internet address. If the two proxy results are equivalent, then the request is directed to the local client assistant, otherwise the request is directed according to the previous proxy results. If the testing of the public Internet address had resulted in the use of a proxy, then the local client assistant will route its requests to the proxy so indicated. |

A correcting asynchronous Successive-Approximation Register (SAR) analog-to-digital converter (ADC) detects and corrects metastability errors. An analog signal is synchronously sampled by a system clock, but data bits are converted asynchronously. A valid detector compares true and complement outputs of a comparator that compares the sampled voltage to a DAC voltage generated from digital test value from the SAR. Once the true and complement outputs diverge past logic thresholds, the valid detector activates a VALID signal indicating that comparison is completed. The compare result is then latched in as a data bit and the SAR advances to the next test value. Once all bits have been converted, an End-of-Conversion (EOC) is signaled. If the EOC does not occur by the end of the system clock, a metastability error is detected. The current bit that never finished comparison is forced high and all other unconverted bits are forced low. |
