Abstract: A technique wherein High Availability (HA) hardware is used to automatically validate control and configuration registers, e.g. automatically generate parity, detect parity errors, and report errors within software-written configuration and control registers of ASIC and IC products. Parity control logic and Masking Registers are utilized to facilitate automatic parity generation and subsequent parity error reporting. The specific location of where the error occurred can be stored to enable software to correct and/or reconfigure the registers. The HA hardware verifies the validity of control and configuration registers coupled to a bus, utilizing idle cycles in addition to valid bus cycles so there is no impact on system throughput.

Abstract: A correlation system for use in wireless direct sequence spread spectrum systems includes a RF down converter which receives an encoded RF signal and generates therefrom analog in-phase (I) and quadrature (Q) signal components. These components are digitized and the digitized signals are then passed to each of the high precision correlator circuit and a low precision correlator circuit. The low precision correlator circuit consist of a bank of a plurality of low precision correlators which receive the I and Q signal components as inputs and correlates the same with progressively phase shifted or delay pseudo noise (PN) codes. A low precision correlation circuit locks on to the appropriate PN code phase shift or delay and applies the same as a reference PN code to the high precision correlation circuit for data acquisition and demodulation.
