Abstract
A content addressable memory (CAM) of a data processing device can operate in a normal mode or a test mode. In the normal mode, the CAM provides a match value in response to determining that a received data value matches one of a plurality of values stored at memory locations of the CAM. In a test mode of operation, a plurality of test signals are applied to the CAM, and the CAM provides a match value in response to assertion of one of the test signals. The match value is applied to a functional module associated with the CAM to determine a test result. Accordingly, the test signals applied to the CAM provide a flexible way to generate match values and apply those values to the functional module during testing of the data processing device.
