A semiconductor integrated circuit of the invention comprises a plurality of cores, and an interconnecting network including adaptors connected to each of the cores and a plurality of routers connecting the adaptors to communicate therebetween. Transmission side adaptors store first delivery information, and control delivery of the request signal to be received from the first core in accordance with the first delivery information. Reception side adaptors store second delivery information, and control delivery of the request signal to be received through the interconnecting network to the second core in accordance with the second delivery information. The first delivery information and the second delivery information are hierarchically set.

摘要:
Provided is the information communication processing device capable of executing terminal function switching control in linkage with an external communication content on one information communication processing device based on the external communication content without a problem in switching. The information communication processing device has at least one information processing device having a plurality of function environments for executing an application, and a switching control unit for switching a function environment, in which the switching control unit determines a function environment to be switched based on contents of communication with the outside of the information communication processing device and sets context of the function environment to be switched at context of a function environment being executed, thereby executing switching to the function environment to be switched.
