Abstract
Microprocessor resource utilization by a searching process are controlled by determining a search window size, accessing a lookup table to determine an integration interval and a number of non-coherent passes, and commanding a searching process to execute a multipath search according to these parameters. The lookup table comprises a plurality of integration intervals and corresponding number of non-coherent passes indexed according to search window such that an execution duration of the search process remains nominally constant over a variety of search window sizes.
Claims20
In a wireless communication device including a search engine and a microprocessor operably configured to execute searches at a desired search window size from amongst plural possible search window sizes, a method comprising the microprocessor performed steps of:
- identifying a currently desired search window size;
- identifying at least one search parameter associated with the currently desired search window size which when passed to the search engine allows the search engine to perform a multipath search the duration of which is nominally constant relative to the duration of the plural possible search window sizes;
- and
- passing the identified currently desired search window size and search parameter to the search engine to execute the multipath search.
A wireless communication device including a search engine and a microprocessor operably configured to execute searches at a desired search window size from amongst plural possible search window sizes, comprising:
- means for identifying a currently desired search window size,
- means for identifying at least one search parameter associated with the currently desired starch window size which when passed to the search engine allows the search engine to perform a multipath search the duration of which is nominally constant relative to the duration of the plural possible search window sizes;
- and
- means for passing the identified currently desired search window size and search parameter to the search engine to execute the multipath search.
