INTER-COMPONENT COMMUNICATION INCLUDING SLAVE COMPONENT INITIATED TRANSACTION

摘要

Component apparatuses with inter-component communication capabilities, and system having such component apparatuses are disclosed herein. In embodiments, such a component may include a number of control pins including a clock pin, a number of data pins, and a logic unit. The logic unit may be configured to receive a clock signal from another component through the clock pin, to provide an alert signal to the other component through a selected one of the control and data pins to initiate a transaction with the other component, to receive in response to the alert signal from the other component through the data pins a status request to determine nature of the transaction, and to provide in response to the status request to the other component through the data pins a status to indicate the nature of the transaction. The provision of the alert signal, the receipt of the status request and the provision of the status may be in reference to the clock signal. Other embodiments may be disclosed or claimed.

主权项

1. A device comprising:
a channel capability register; a configuration register; a clock (CLK) pin to receive a clock signal; a plurality of input/output (I/O) pins [n:0]; a chip select pin; and a logic unit, wherein
the logic unit is to receive a command from at least one I/O pin andthe logic unit is to cause transmission of a response using at least one I/O pin in response to the command, wherein
the command comprises a GET_CONFIGURATION or aSET_CONFIGURATION command,the GET_CONFIGURATION command is to cause discovery of capabilities of the device,the SET_CONFIGURATION command is to cause capabilities setting of the device,the logic unit is to receive one or more of an address or cyclic redundancy check (CRC) after the GET_CONFIGURATION command,the logic unit is to receive one or more of an address, data, or CRC after the SET_CONFIGURATION command, andthe response comprises one or more of response code, status, data, or CRC.
