Abstract: A cache, including a cache memory, is configurable to operate in a cache mode and a trace mode. When the cache is operating in the cache mode, the cache memory stores a copy of a portion of data that is stored in another memory external to the cache, and a received data access request is processed by retrieving a copy of a portion of data identified in the received data access request from the cache memory (if the cache memory stores a copy of the portion of data), or by forwarding the data access request to a data access request processing means external to the cache (if the cache memory does not store a copy of the portion of data). When the cache is operating in the trace mode, data access requests received by the cache are monitored and information relating to a received data access request is captured and stored in the cache memory.

Abstract: An analog switch includes a transistor whose source connected to a signal input and whose drain is connected to a signal output. An output of a gate control circuit is connected to the transistor gate. A first input of the gate control circuit is connected to the source of the transistor. The gate control circuit responds to a logic transition of an enable signal received at a second input by pre-charging a substantially constant gate-to-source voltage across the transistor. This voltage is stored by a gate-to-source connected capacitor. In one steady-state logic condition of the enable signal, the gate control circuit operates to turn off the transistor. In another steady-state logic condition of the enable signal, the gate control circuit permits the signal received at the signal input to drive the gate of the transistor with a voltage offset by the substantially constant gate-to-source voltage stored on the capacitor.
