Renesas Electronics has filed a patent for systems and methods to control data transactions between master and slave devices. The patent describes different operation modes, including one where the master device performs data transactions with multiple slave devices via a network element, another where the master device is disconnected and multiple agents fulfill the transactions, and a third mode where the master device interacts with a subset of slave devices while being disconnected from another subset.

A recently filed patent (Publication Number: US20230315653A1) describes an apparatus that includes a master port connected to a master device, multiple slave ports connected to slave devices, a network element connected to the master port, and a controller connected to both the master port and the slave ports. The controller is designed to control the slave ports to operate in different operation modes.

The first operation mode allows the master device to perform data transactions with the slave devices through the network element. In this mode, the slave devices are interconnected via the network element.

The second operation mode disconnects the master port from the slave ports and enables a group of circuit blocks connected to the slave ports to handle the data transactions with the slave devices. This mode eliminates the need for the master device to be directly involved in the data transactions.

The third operation mode involves the master device performing data transactions with a subset of the slave devices through the network element, while being disconnected from another subset of the slave devices. This mode allows for selective communication between the master device and the slave devices.

The apparatus described in the patent aims to provide flexibility and control in managing data transactions between the master device and the slave devices. By offering different operation modes, it allows for various configurations and scenarios based on the specific requirements of the system.

This patent filing suggests a potential solution for optimizing data transactions in a networked environment. The apparatus's ability to switch between different operation modes provides versatility and adaptability, allowing for efficient communication between the master device and the slave devices. This innovation could have implications in various industries that rely on networked systems, such as telecommunications, automation, and IoT applications.
