Systems and techniques are disclosed relating to communications. The systems and techniques include determining the temperature and process speed of chips used in communications devices. The systems and techniques include measuring the output of ring oscillators embedded in the chips, and calculating the temperature and process speed therefrom.

Identifying process and temperature of silicon chips

Techniques for scalable CDMA demodulation with maximum response latency are disclosed. In one aspect, a finger timing unit generates signals indicating cycle boundaries for a plurality of fingers, and an offline processing unit processes stored samples for those fingers in response to the signals. In another aspect, incoming samples are stored in a RAM, while finger timing is maintained using a plurality of counters. The RAM address is stored on symbol boundaries. Symbols for each finger are generated in an offline processing unit, clocked at a higher speed than the finger counters, from a RAM location computed using the stored RAM address. Various other aspects are also presented. These aspects provide for decoupling of the chip rate processing from chip time, which allows a single offline processing unit to service a plurality of fingers, thus reducing additional hardware required to support additional fingers while maintaining maximum latency requirements.
