INTEGRATED CIRCUIT AND METHOD FOR SENDING REQUESTS

摘要

In networks on an integrated circuit a first module (M1) typically has access to an address space (ADDR-SPC), wherein addresses identify locations within second modules. It may be necessary to address two or more second modules (M2) simultaneously. In that case, the first module replicates a request (SREQ) and sends the resulting plurality of requests to the second modules (M2). This causes a large burden on the first module. The integrated circuit and the method according to the invention overcome this shortcoming, because the network can provide a multicast request to at least two second modules (M2) in response to a single request (SREQ) from the first module (M1). For this purpose, the network can comprise a facility to map a multicast address onto two or more further addresses. Alternatively, a connection identifier 10 can be sent along with a request (SREQ), which identifies a multicast connection.
