Abstract: A memory controller is provided, which includes a processor having a plurality of processing cores, and a lookup acceleration circuit. The lookup acceleration circuit includes a message processing circuit and a logical-to-physical mapping table lookup circuit. The message processing circuit receives request messages from the processing cores using request queues, and puts an incoming request message to a collision pending queue in response to detection of a collision between a first logical address range within the incoming request message and second logical address ranges within message contexts corresponding to active request messages. The logical-to-physical mapping table lookup circuit looks up a logical-physical mapping table in a volatile memory to convert the second logical address ranges into first physical addresses. The message processing circuit performs memory access operations corresponding to the active request messages on the volatile memory using the first physical addresses.

Abstract: A method and system used to detect characteristic information of internal body tissues applies multiple AC currents of different frequencies simultaneously to a human or animal body. After the modulated voltage signals are received, they are demodulated. Information from both the cardiovascular system and the surrounding tissues is extracted from the carrier waves of specified frequencies. System identification or channel estimation procedures are performed to separate the information from the cardiovascular circulation system and the surrounding tissues. The resistance and capacitance of the cardiovascular system and surrounding tissues are calculated separately. The calculated resistance and capacitance values are used to represent the states of body fluid and cardiovascular circulation. As a result, relevant state information is obtained accurately and reliably to enable accurate measurements of targeted tissues for acquiring health states.
