An apparatus and method for efficiently managing data cache load misses is described in connection with a multithreaded, pipelined multiprocessor chip. A CMT processor keeps track of load misses for each thread by issuing a load miss signal each time a load instruction to the data cache misses. A detection logic functionality in the IFU responds the load miss signal to determine if a valid instruction from the thread is at the one of the pipeline stages. If no instructions from the thread are detected in the pipeline, then no flush is required and the thread is placed in a wait state until the requested data is returned from higher order memory. If any instruction from the thread is detected in the pipeline, the thread is flushed and the instruction is re-fetched.

The present invention eliminates a transmission-waiting operation which is unnecessary while accommodating a prioritized traffic. Although a communication station enters a transmission-disallowed state in response to detection of a signal addressed to another station in accordance with medium access control based on CSMA, if the communication station receives a frame transmitted with priority to a local station during the transmission waiting, it cancels the transmission-disallowed state, sends back a frame responding the frame transmitted with priority and effectively operates a transmission prioritized period. The communication station starts a search procedure to perform a processing of evading duplication of the transmission prioritized periods if it judges a possibility of a problem occurring in a time zone in which reception with priority is possible.
