Detailed Description
For a better understanding and explanation of the present invention, reference will now be made in detail to the present invention as illustrated in the accompanying drawings. The present invention is not limited to these specific embodiments only. Rather, modifications and equivalents of the invention are intended to be included within the scope of the claims.
It should be noted that numerous specific details are set forth in the following detailed description. It will be understood by those skilled in the art that the present invention may be practiced without these specific details. In the following detailed description of various embodiments, structures and components well known in the art are not described in detail in order to not unnecessarily obscure the present invention.
The present invention provides a method for configuring synchronization between an embedded chip and an external device, referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of the method for configuring synchronization between an embedded chip and an external device according to the present invention, the method includes:
step S100, presetting a multi-core CPU in an embedded chip, and a time-sharing operating system and a real-time operating system which run in parallel and are communicated with each other in the multi-core CPU;
step S200, the time-sharing operating system generates configuration parameters and sends the configuration parameters to the real-time operating system;
and step S300, the real-time operating system configures the synchronous operation of the embedded chip aiming at the external equipment according to the configuration parameters.
Specifically, considering that the specific product targeted by the synchronization method provided by the present invention is an embedded automatic road-finding robot device such as an unmanned vehicle, typically, the embedded chip in step S100 is implemented as a System On Chip (SOC), the multicore CPU is a central processing unit integrated on the SOC, the central processing unit has at least two operation engine cores, and in order to ensure that the time-sharing operating system and the real-time operating system can run in parallel in the multicore CPU, the SOC is preferably designed and implemented such that one core of the multicore CPU is used for running the real-time operating system, and the other cores of the multicore CPU are used for running the time-sharing operating system. Typically, the time-sharing operating system is a lightweight time-sharing operating system adapted to the SOC, such as Linux, Android, or Quick Unix, and the real-time operating system is a real-time operating system (RTOS) adapted to the SOC having an event-timely response characteristic, such as FreeRTOS; the operation of the specified split operating system on a part of cores in the multi-core CPU can be realized by a kernel configuration mode of the time-sharing operating system. As will be understood by those skilled in the art, the RTOS adapted to the SOC is specifically designed for the functions of the SOC, the threads in the RTOS are preferably designed to process data generated by external devices continuously and directly transmitted to the SOC, so as to ensure that the SOC can quickly respond to external events, and the time-sharing operating system is mostly used for implementing functions such as logic scheduling and human-computer interaction at an application program level. Given the nature of an RTOS and the computational resources allocated to the RTOS, it is not generally considered that the RTOS is designed to also assume the form of a human-machine interface that provides the SOC.
In this embodiment, a series of configuration operations required for synchronizing the external device are executed by the real-time operating system, and steps required to be manually participated or automatically executed in the configuration parameters involved in the configuration operations are assigned to the time-sharing operating system for execution, and data transmission is required between the real-time operating system and the time-sharing operating system.
In step S200, the time sharing operating system generates configuration parameters and sends the configuration parameters to the real-time operating system. It will be appreciated by those skilled in the art that with reference to the existing implementation principles of embedded chips, the configuration operation includes not only an adaptive configuration of the properties of the synchronization signals, but optionally also an adaptive configuration of the interfaces of the embedded chip. Typically, the interface of the embedded chip comprises a communication message interface in the embedded chip for performing message interaction with the external device; and/or a synchronous signal interface which is arranged in the embedded chip and transmits synchronous signals with the external equipment. For example, when the embedded chip is matched with an external device with a PPS synchronization function, the synchronization signal interface is a chip pin for sending or receiving PPS pulses, and the communication message interface is a serial port for sending or receiving a GPRMC message.
The configuration parameters are determined according to the specific implementation requirements of the external device accessed by the embedded chip during synchronization, and are used for the configuration processing in step S300. More specifically, in the face of a change in a synchronization mode of the external device and a change in an attribute of an input/output synchronization signal, it is necessary to trigger an update of the configuration parameter, and the real-time operating system cannot autonomously implement the update change of the configuration parameter, and it is necessary that data provided by the time-sharing operating system trigger the real-time operating system to implement the update change, and meanwhile, the real-time operating system further needs to configure the synchronization signal interface and/or the communication data interface according to the configuration parameter. In this embodiment, the configuration parameters are data provided by the time-sharing operating system. Configuration operations for the communication message interface include, but are not limited to: selecting a plurality of communication message interfaces, such as selecting a serial port or an I2C bus interface for communication; or changing the working condition attribute of the communication message interface, for example, adjusting the data transmission rate of the serial port. Configuration operations for the synchronization signal interface include, but are not limited to: the selection of a plurality of the synchronous signal interfaces is, for example, to select a PPS synchronous interface or a synchronous triggered synchronous interface, or to change the operating condition attribute of the synchronous signal interface, for example, to select a pull-up input mode or a pull-down input mode of the synchronous signal interface.
Typically, the external device is a sensor, and the sensor includes but is not limited to a GPS synchronization sensor, a synchronization trigger type sensor or a synchronization output type sensor according to the synchronization mode thereof; during synchronization, the embedded chip may output a synchronization signal to the external device, or the embedded chip may receive a synchronization signal sent by the external device.
In the process of generating the configuration parameters by the time-sharing operating system in step S200, the process may be implemented as: and outputting an interactive interface by a configuration program running in the time-sharing operating system, and generating the configuration parameters according to the operation of a user on the interactive interface. Usually, the interactive interface is used to show the parameters involved in the configuration parameters, and the user's operation on the interactive interface is usually a character output operation for the above parameters. Optionally, the process may be further embodied as: the configuration program sends parameter query information to the real-time operating system, the parameter query information triggers the real-time operating system to detect the attribute parameters of the interface of the embedded chip and/or the external equipment, and returns the attribute parameters to the time-sharing operating system, and the time-sharing operating system automatically generates the configuration parameters according to the attribute parameters. The real-time operating system can detect the attribute parameters of the interfaces of the embedded chips by sending test data to the interfaces of the embedded chips by the real-time operating system, wherein the test data is used for determining that the interfaces of the embedded chips are suitable for the working parameter range of the external equipment. The real-time operating system may detect the attribute parameters of the external device by means of a detection module coupled to the external device, the detection module having a data exchange interface recognizable to the real-time operating system and being triggered to generate a detection signal for the external device, the result of the detection signal being fed back to the real-time operating system via the data exchange interface, the attribute parameters being the result itself or a direct/indirect data transformation product thereof. In addition, the time-sharing operating system automatically generates the configuration parameters according to the attribute parameters, and the configuration parameters can be realized by using a preset database of a predetermined computer program running in the time-sharing operating system. In a specific implementation, the real-time operating system may be selected to detect only one of the interface of the embedded chip and the external device, that is, the configuration parameter may be generated according to the detection result, and in a necessary case, the real-time operating system may also be configured to detect both the interface of the embedded chip and the external device, so as to ensure the correctness of the generation of the configuration parameter.
After the configuration parameters are generated, the time-sharing operating system sends the configuration parameters to the real-time operating system, and an interface for mutual communication between the time-sharing operating system and the real-time operating system may be a shared memory, a universal serial bus, or the like, which can meet the requirement that the time-sharing operating system transmits the configuration parameters to the real-time operating system at a high speed, which is not limited in the present invention.
In step S300, the real-time operating system configures the embedded chip for the synchronous operation of the external device according to the configuration parameters. Specifically, the real-time operating system executing the configuration processing means that the real-time operating system configures attributes of an interface of the embedded chip according to the configuration parameters, and configures attributes of a synchronization signal output by the embedded chip or attributes of a received synchronization signal. In this embodiment, the configuration process is designed to be executed by the real-time operating system.
According to the specific implementation requirement of the external device accessed by the embedded chip during synchronization, typically, the configuration parameters include: the attribute parameters of the synchronous signals and the attribute parameters of the interface of the embedded chip. Wherein the attribute parameter of the synchronization signal is used to define the attribute of the synchronization signal, and the attribute of the synchronization signal includes but is not limited to: rising edge trigger or falling edge trigger of the input synchronous signal, and the like, and pulse width or frequency of the output synchronous signal, and the like. The attribute parameters of the interface are used to define the attributes of the interface, for example, the common communication message interfaces on the embedded chip include a serial port, an I2C bus interface, an SPI bus interface, and the like, and accordingly the attributes of the communication interface include but are not limited to: baud rate, data bit length, start bit, stop bit, parity check, etc. of the serial port, transmission rate, operating mode, duty ratio of SCL line clock, device address, etc. of the I2C bus interface, master-slave mode, data frame length, clock polarity, clock phase, MSB/LSB anticipatory, etc. of the SPI bus interface. The common synchronous signal interface on the embedded chip is a GPIO port, and the attributes of the corresponding synchronous signal interface include, but are not limited to: a pull-up input mode, a pull-down input mode, etc. of the GPIO port.
By implementing the steps S100 to S300, dynamic adjustment of the synchronization mode of the embedded chip can be realized, so that the synchronization mode of the embedded chip can be adaptively updated in time according to synchronization requirements of different types of external devices, and no additional adaptive chip or adaptive circuit needs to be added, thereby improving flexibility and applicability of the embedded chip in practical application and not increasing system redundancy and cost of the embedded chip.
Preferably, the specific embodiment shown in fig. 1 further comprises:
and step S400, the real-time operating system sends state information to the time-sharing operating system according to the configuration processing result. The purpose of executing step S400 is to use the state information to notify the time sharing operating system that the current configuration process is completed, so that the time sharing operating system can return to execute step S200 and step S300 again, or execute other additional tasks, and also so that the time sharing operating system can send a feedback to the user whether the configuration process is successful.

Rather, the steps depicted in the flowcharts may change the order of execution. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions.
Accordingly, the present invention also discloses one or more computer-readable media storing computer-executable instructions that, when used by one or more computer devices, cause the one or more computer devices to perform a configuration method of synchronization of an embedded chip and an external device as described above, such as the configuration method shown in fig. 1.
