Semiconductor device package having a switcher connecting plural processing elements
View Patent ↗A package includes a plurality of processors 101-104 as processing elements. One of the processing elements is selected as a switcher 110 and the switcher is located at the center of the package. Each of the processors 101-104 includes a corresponding network interface 111-114 which has communication function, and each network interface 111-114 is connected to the switcher 110 . Thus constructed packages are laminated and the switchers 110 of the packages are connected to each other via a router 115 and an extra communication port 120 to produce a system LSI.
