摘要： Provided are a high-performance wrapper circuit for a globally asynchronous locally synchronous (GALS) system and a synchronization method using the same, which are capable of solving a synchronization problem caused when data are transmitted between locally synchronous modules employing different clocks, and a method for operating the wrapper circuit. The GALS system includes a clock generator for supplying an operation clock to a locally synchronous module, a sender port for transmitting data to the outside according to a data transmission request signal output from the locally synchronous module, and generating a first clock stop signal for stopping an operation of the clock generator, and a receiver port for receiving data from the outside, and generating a second clock stop signal for stopping the operation of the clock generator. The sender port generates the first clock stop signal to the clock generator when a next data transmission request signal is received before completing a data transmission performed by a previous data transmission request signal output from the locally synchronous module.
