Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The Company sold its baseband chipset business and related support operations, or Baseband Chipset Business, to MediaTek Inc., during the first quarter of fiscal 2008. The Company has reflected the financial results of this business as discontinued operations in the condensed consolidated statements of income for all periods presented. Certain amounts reported in previous years have been reclassified to conform to the fiscal 2012 presentation. Such reclassified amounts are immaterial. The Company has a 52-53 week fiscal year that ends on the Saturday closest to the last day in October. Fiscal 2012 is a 53-week fiscal year and fiscal 2011 was a 52-week fiscal year. The additional week in fiscal 2012 was included in the first quarter ended February 4, 2012. Therefore, the first nine months of fiscal 2012 included an additional week of operations as compared to the first nine months of fiscal 2011.
