The major procedure controller creates proper addresses, control signals for memory read as well as compose procedures, and also control signals for locking information at the host as well as LCA2 side. The control system is composed of the major procedure controller as well as the information course selector. The information course selector establishes the choose lines of the multiplexor/demultiplexor reasoning to move information in between the I/O host information register and also the host PC/RAM information bus. Because of the various size of the datapaths at the host PC/RAM side and also the LCA2 side, the user interface controller carries out extra multiplexing/demultiplexing of information lines. The primary job of the controller throughout this stage is to move the examination vectors kept in the external memory to the inputs of the LCA2 as well as to move the acquired result signals of the created circuit back to the external memory.
