Abstract:
1. An access control device for controlling access to a first device connected with a first bus conforming to a first standard, said first device conforming to said first standard and access to a second device connected with said first bus, said second device conforming to a second standard, said access control device comprising: a first signal generator which generates a first transaction start signal indicating start of a transaction for said first device; and a second signal generator which generates a second transaction start signal for said second device based on said first transaction start signal, wherein the first signal generator generating the first transaction start signal and the second signal generator generating the second transaction start signal are adapted to and result in the first device communicating with the second device without employing a first standard-second standard bridge even though the first device conforms to the first standard and the second device conforms to the second standard, the second standard being different than the first standard, where otherwise the first device is unable to communicate with the second device due to the second standard being different than the first standard.
