9. Real Time Systems Lab rtlab.knu.ac.kr 9 Research Topics  Cacheable Replicated Tuple Space Architecture - Some important or periodic data which is based on IEEE1394 can be handled by hardware user logic.  Improvement of the Replicated Repository Scheme - the replicated repository scheme is useful for distributed home network environment, but it has some restrictions related to the scale of home network and the number of devices.  Difficult Work  Consideration about embedding the PLC(Power Line Communication) based H/W and S/W - As shown in Case Study…  AV1394 Analog Multiplexer - Now, one AV1394 board can communicate with only one analog AV device unless some analog multiplexer doesn’t exist
