Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations In September 2007, the Company entered into a definitive agreement to sell its Baseband Chipset Business to MediaTek Inc. The decision to sell the Baseband Chipset Business was due to the Company’s decision to focus its resources in areas where its signal processing expertise can provide unique capabilities and earn superior returns. During fiscal 2008, the Company completed the sale of its Baseband Chipset Business for net cash proceeds of $269.0 million. The Company made cash payments of $1.7 million during fiscal 2009 related to retention payments for employees who transferred to MediaTek Inc. and for the reimbursement of intellectual property license fees incurred by MediaTek. During fiscal 2010, the Company received cash proceeds of $62.0 million as a result of the receipt of a refundable withholding tax and also recorded an additional gain on sale of $0.3 million, or $0.2 million net of tax, due to the settlement of certain items at less than the amounts accrued. In fiscal 2011, additional proceeds of $10.0 million were released from escrow and $6.5 million, net of tax, was recorded as additional gain from the sale of discontinued operations. The Company does not expect any additional proceeds from this sale.

Disclosure of accounting policy for any discontinued operations. The results of operations of a component of an entity that either has been disposed of or is classified as held for sale is reported in discontinued operations if both: (a) the operations and cash flows of the component have been (or will be) eliminated from the ongoing operations of the entity as a result of the disposal transaction and (b) the entity will not have any significant continuing involvement in the operations of the component after the disposal transaction. If the entity elects to allocate interest expense to a discontinued operation, it may disclose its accounting policy for this election and describe its method of allocation.
