Abstract:
Described is an I3C Repeater. The I3C Repeater may have a first circuitry with an I3C interface, a second circuitry with an I2C interface, and a datapath circuitry coupled to the first circuitry and the second circuitry. The second circuitry may be operable to convert a transaction received on the I2C interface into a transaction for the I3C interface, and to convert a transaction received on the I3C interface into a transaction for the I2C interface. The I3C Repeater may also have additional circuitries operable to convert transactions received on one of an SPI interface, a UART interface, and a Debug bus interface into transactions for the I3C interface, and vice-versa.

Abstract:
Embodiments include apparatuses, methods, and systems for testing that include a programmable tester coupled to a master-slave device network having a master device and at least one slave device. The programmable tester is to receive a configuration mode from a host to test a function of a selected device of the master device or the at least one slave device. The configuration mode is to indicate that the programmable tester is to be configured to operate in a slave mode or in a master mode. The programmable tester is further configured according to the configuration mode, to send test data to test the function of the selected device, determine a test result based on response data by the selected device to the test data, and indicate whether the selected device is in a faulty state with respect to the function. Other embodiments may also be described and claimed.

Abstract:
Methods and apparatuses relating to circuitry for multilane serial bus communications are described. In an embodiment, an apparatus includes a serial bus controller, upstream serial bus lanes, a single downstream serial bus lane, and a host/device lane controller. The serial bus controller is to send and receive data transmissions to and from serial bus devices. The upstream serial bus lanes correspond to the serial bus devices and are associated with serial port addresses. The host/device lane controller is to receive data transmissions through the upstream serial bus lanes and includes a port address assignment circuit and a multiplexer. The port address assignment circuit is to assign serial port addresses to data transmissions, to be included in data transmissions to identify the upstream serial bus lanes through which the data transmission was received. The multiplexer is to forward data transmissions from upstream serial bus lanes to the downstream serial bus lane.
Abstract:
A port of a first integrated circuit is coupled to a first communication path. Configuration information is communicated between a connector coupled to a second device and a second integrated circuit through the port and the first communication path. The port is decoupled from the first communication path. The port is coupled to a second communication path. Data is communicated between the connector and the second integrated circuit through the port and the second communication path.
Abstract:
Techniques for embedded high speed serial interface methods are described herein. The method includes issuing a single-ended one (SE1) signal on each of a pair of embedded high speed serial interface data lines, the SE1 indicating a register access protocol (RAP) message follows the SE1 signal. The method also includes accessing a register of an embedded high speed serial interface component based on the RAP message.
