摘要：Now a day’s embedded systems are more complex and complicated as compared to the old one. Low power microcontrollers arelimited to a specific task. But current time demand is data specific which requires more data processing. Re configurability is also aninteresting feature of current time embedded system. So we have to develop a system that is easily re configurable as per our requirement.Cost is also a design factor; we have to develop a system that its cost will not increase. High power microcontrollers are able to processhigher data at a higher speed taking higher amount of power. But when our task is limited to power, cost; high power microcontrollers can’tbe used. High power microcontrollers become problematic for the battery operated embedded systems where power backup is limited. Toovercome this problem we are developing Multi-microcontroller System on Programmable Chip (MMSoPC). Synchronization is a keyproblem in multi-microcontroller systems to operate simultaneously. To synchronize the buses of the microcontrollers, network on chip(NoC) is the solution. Local system buses are connected to a common system bus i.e. global system bus. Global buses are externallyavailable to the outside for different interfacing of various components/peripherals etc. So there is a need of synchronization of local systembuses to the global system bus
