The Company designs, develops, manufactures and markets a broad range of integrated circuits. The Chief Executive Officer has been identified as the Chief Operating Decision Maker.

Revenue Trends by End Market

The following table summarizes revenue by end market. The categorization of revenue by end market is determined using a variety of data points including the technical characteristics of the product, the “sold to” customer information, the “ship to” customer information and the end customer product or application into which the Company’s product will be incorporated. As data systems for capturing and tracking this data evolve and improve, the categorization of products by end market can vary over time. When this occurs, the Company reclassifies revenue by end market for prior periods. Such reclassifications typically do not materially change the sizing of, or the underlying trends of results within, each end market.

Revenue Trends by Product Type

The following table summarizes revenue by product categories. The categorization of the Company’s products into broad categories is based on the characteristics of the individual products, the specification of the products and in some cases the specific uses that certain products have within applications. The categorization of products into categories is therefore subject to judgment in some cases and can vary over time. In instances where products move between product categories, the Company reclassifies the amounts in the product categories for all prior periods. Such reclassifications typically do not materially change the sizing of, or the underlying trends of results within, each product category.

Revenue Trends by Geographic Region

During the second quarter of fiscal 2012, the Company revised its method for classifying revenue by geographic region to more accurately reflect the primary location of our customers’ design activity for our products. Prior periods have been reclassified to align with this definition. In general, the prior classification method reflected the customers’ manufacturing location or the distributors’ stocking territory. No changes have been made to the Company’s revenue recognition policy. Revenue by geographic region for the three- and nine-month periods ended August 4, 2012 and July 30, 2011 was as follows:
