Embodiment Construction

[0033] Figure 1A A known configuration of a communication router R1, R2 in a network on an integrated circuit is shown. The network comprises a set of routers R1, R2 connected by links L1, L3. Both links operate at a specific clock frequency f1. In terms of performance (clock frequency, phase, bit width, etc.), the two routers R1, R2 see the same view on the link L1 between said routers. This is the prevailing view of the network on a chip.

[0034] Figure 1B A known configuration of communication routers R1 , R2 comprised in the same network but in different subnets 1 , 2 is shown. For example, the subnets may reside on different boards, chips or dies. Alternatively, the subnets may reside on a single integrated circuit, but they may have different power or voltage domains. For the correct functioning of this network, said routers R1, R2 should see the same picture (in terms of performance) on the link L1 between them, but the performance of L1 may be different from o...

Abstract

The invention relates to a data processing system and a method for synchronizing data traffic. The invention relies on the perception that the lack of synchronization of data traffic is primarily caused by the use of different schemes for reservation of resources. According to the invention, a conversion unit is provided which converts first data into second data, the first data being controlled by a first scheme for reservation of resources and the second data being controlled by a second scheme for reservation of resources. The conversion unit may be referred to as a network-level bridge (NWB). For example, the different schemes for reservation of resources may be based on slot tables, in which case the conversion unit converts the slot assignments for the first data into the slot assignments for the second data.

Description

technical field [0001] The invention relates to a data processing system on at least one integrated circuit, the data processing system comprising at least two modules and a network for transferring data between said modules, wherein the network comprises a first subnetwork and a second subnetwork. Two subnets, the first subnet uses a first resource reservation scheme, and the second subnet uses a second resource reservation scheme. [0002] The invention also relates to a method for converting data in a data processing system on at least one integrated circuit, the data processing system comprising at least two modules and a network for transferring data between said modules, wherein the The network includes a first subnet using a first resource reservation scheme and a second subnet using a second resource reservation scheme. Background technique [0003] Network-on-Chip (NoC) has been proposed and widely accepted as a suitable solution to the problems related to the inte...
