US 2017/0270070 A1 · METHOD OF HANDLING TRANSACTIONS, CORRESPONDING SYSTEM AND COMPUTER PROGRAM PRODUCT

Abstract

A system, such as a System-on-Chip includes an interface component or PLUG which generates transactions over an IP block, such as an interconnect serving one or more clients via virtual channels. The client or clients are mapped onto the virtual channels via client/virtual channel mappings. The virtual channels are provided as a first set of virtual channels in the interface component which cooperate with a second set of virtual channels in the IP block. First and second client/virtual channel mappings for the first set of virtual channels and the second set of virtual channels are provided. The first and second client/virtual channel mappings are separately programmable and mutually decoupled from one another.

Claims20

Dependent claims

A system, comprising:

an interface component;
an IP block having a message transfer interface block, the IP block associate with a plurality of N clients;
a logical network, the logical network configurable as a plurality of virtual channels, the plurality of virtual channels including a first set of internal virtual channels in said interface component and a second set of system virtual channels in said IP block, the first set of internal virtual channels and second sets of system virtual channels configured for separate programming;
and
an arbitration unit configured to apply a weighted least recently used (WLRU) arbitration procedure to a plurality of data transfers, each data transfer associated with a different client, when the plurality of data transfers are communicated via the same internal virtual channel.

2 more elements

A method of arbitrating traffic between a plurality of clients, comprising:

providing an interface component;
providing an IP block having a message transfer interface block, the IP block associate with the plurality of clients;
providing a plurality of virtual channels in a logical network, the plurality of virtual channels including a first set of internal virtual channels in said interface component and a second set of system virtual channels in said IP block;
separately programming the first set of internal virtual channels and the second set of system virtual channels;
and
with an arbitration unit, applying a weighted least recently used (WLRU) arbitration procedure to a plurality of data transfers, each data transfer associated with a different client, when the plurality of data transfers are communicated via the same internal virtual channel.

3 more elements

A non-transitory computer readable medium containing instructions to control at least one computing device, the instructions including software code portions to implement a method, the acts of the method comprising:

establishing a plurality of virtual channels in a logical network, the plurality of virtual channels including a first set of internal virtual channels in an interface component and a second set of system virtual channels in an IP block, the IP block associated with a plurality of clients;
and
arbitrating data passed between ones of the plurality of clients by applying a weighted least recently used (WLRU) arbitration procedure to a plurality of data transfers communicated via the same internal virtual channel, each data transfer associated with a different client.

Dependencies are inferred from the claim text.
