摘要： Systems or methods of the present disclosure may provide a programmable logic device including a network-on-chip (NoC) to facilitate data transfer between one or more main intellectual property components (main IP) and one or more secondary intellectual property components (secondary IP). To reduce or prevent excessive congestion on the NoC, the NoC may include one or more traffic throttlers that may receive feedback from a data buffer, a main bridge, or both and adjust data injection rate based on the feedback. Additionally, the NoC may include a data mapper to enable data transfer to be remapped from a first destination to a second destination if congestion is detected at the first destination.

摘要： Systems or methods of the present disclosure may provide systems and techniques for controlling access to components and resources of an IC device by multiple tenants. For example, a method may include: receiving access control instructions defining a first mapping between one or more tenants and respective security attributes and a second mapping between one or more agent identifiers and respective access permissions; receiving a communication intended for a target component of the IC device; determining an origin tenant from which the communication originated; determining a security attribute associated with the origin tenant based on the first mapping; and sending the communication and an agent identifier comprising the security attribute and an initiator bridge identifier to a corresponding target bridge, wherein the corresponding target bridge is configured to grant or deny access of the communication to the target component based on the agent identifier and the second mapping.
