Abstract
A method for reducing the number of cycles required for setting up content addressable memory contexts is disclosed. In particular, the method reduces the number of cycles required for setting up multiple contexts of burst operations, in which each context includes the same data key. Each context includes a special field that is set by the user, called a data reuse field. Setting the data reuse field to a first state indicates that the data from the corresponding context is to be used in the operation. Setting the data reuse field to a second state indicates that the data from the most recent operation is to be used instead. Hence the search data key can be written to a single context, avoiding consumption of cycles required for writing the same search data key to subsequent contexts of the burst operation.
