Abstract
A bus system () for a semiconductor circuit transmits data on a networked bus between a first node and at least one second node via a relay device () arranged on the bus. The bus system () includes a first bus of a low delay and a second bus of a high delay. The first node generates a plurality of packets by attaching, to the data stored in a buffer (), information specifying a priority of transmission. The relay device () converts a priority based on a priority conversion rule, which is determined based on a transmission delay of the high-delay bus, allocates a buffer of a destination relay device to which each packet is to be sent, based on the converted priority, and sends packets in a descending order. The relay device () stores packets in a buffer () based on the priority.
