Detailed Description
The following describes in detail specific embodiments of a peripheral chip, an application processor, a terminal device, and a communication method according to the present invention with reference to the accompanying drawings.
Fig. 1 is a schematic diagram illustrating implementation steps of a specific embodiment of a communication method between a peripheral chip and an application processor according to the present invention, including: step S10, the peripheral chip internally temporarily stores the log information; step S11, the peripheral chip sends an upload request to the application processor through a control channel between the peripheral chip and the application processor; step S12, the peripheral chip uploads the log information to the application processor through the data channel between the peripheral chip and the application processor; and step S13, the peripheral chip marks the uploaded log information.
In this embodiment, the peripheral chip is a digital signal processing chip, and may be configured to process an audio signal, and the log information is a log file. In other embodiments, the peripheral chip may also be other small chips that need to interact with the application processor, such as an audio/video codec chip, a radio frequency transceiver chip, and the like.
Referring to step S10, the peripheral chip internally buffers the log information. In this embodiment, in order to ensure that there is enough space for storing log information, a buffer area including a plurality of storage units (slots) is provided in the peripheral chip for temporarily storing the log information, and the application processor also allocates a corresponding buffer area from the memory of the application processor. In this embodiment, the buffer structures respectively disposed in the digital signal processing chip 21 and the application processor 20 are as shown in fig. 2. A buffer 211(log buffer) including a plurality of storage units for storing a log file may be divided in a storage area, such as a Static Random Access Memory (SRAM), in the digital signal processing chip 21. In the present embodiment, 8 memory cells are illustrated as 211a to 211 h. In this step, the digital signal processing chip 21 is additionally required to report the setting rule of the buffer 211 to the application processor 20, so that the application processor 20 establishes a corresponding area for storing the log file reported by the digital signal processing chip 21. The setting rule includes, but is not limited to, the total storage space of the buffer 211, the number of included storage units, and the storage space of each storage unit, etc. For example, the size of the buffer may be 1024 bytes, the size of the memory unit is 128 bytes, and there are 8 memory units in the buffer. Similarly, after the digital signal processing chip 21 is initialized, the application processor 20 is notified of the sizes of the buffer and the storage unit of the digital signal processing chip 21, and the application processor 20 also allocates a buffer from the memory of the application processor 20, and divides the buffer into not less than 8 storage units, each of which has a space of not less than 128 bytes and is used for storing log information from the peripheral chip, and in the present embodiment, is used for storing a log file from the digital signal processing chip 21.
Referring to step S11, the peripheral chip sends an upload request to the application processor through a control channel between the peripheral chip and the application processor. This step may be initiated by the peripheral chip obtaining an external command, or by the peripheral chip having been filled with memory locations in the buffer, or by the peripheral chip having reached a threshold level of memory occupancy in the buffer. In this embodiment, the control channel communication mode between the digital signal processing chip 21 and the application processor 20 is as shown in fig. 3. The control channels of the application processor 20 and the digital signal processing chip 21 are mainly implemented by a mailbox (mailbox) hardware communication mechanism, for example, the digital signal processing chip 21 needs to send an interrupt to the application processor 20, and only needs to write the corresponding command (cmd) and data (data) values into the relevant registers. When the application processor 20 reads the commands and data, the interrupt is executed to process the request from the dsp chip 21, which is similar to the workflow of sending and receiving mail. The command is transmitted through the control channel between the chips, and serial port resources are not occupied.
Referring to step S12, the peripheral chip uploads the log information to the application processor through a data channel between the peripheral chip and the application processor. In this embodiment, the data channel communication mode between the digital signal processing chip 21 and the application processor 20 is shown in fig. 4. The communication mode of the data channel between the digital signal processing chip 21 and the application processor 20 is also that the digital signal processing chip 21 notifies the application processor 20 through the mailbox, the buffer address and size on the digital signal processing chip 21 side, and the application processor 20 directly reads and writes the data with the specified address size in the SRAM on the digital signal processing chip 21 side through the SPI2 APB. In this step, the log file is not transmitted through the printing protocol by using the serial port, because the processing speed of the serial port is very slow and occupies resources, and the peripheral chips are usually small chips and have limited resources. The log file is directly written into the memory of the application processor through the data channel, so that the operation resource of the digital signal processing chip is saved, and the limited resource can be completely used for realizing the operation of the important function of the functions of the chip.
Referring to step S13, the peripheral chip marks the uploaded log information. In this embodiment, further, in order to ensure that the log file is not repeatedly read and written, the dsp 21 may establish a slot index (slot index) to mark the occupied status of the current log information to the storage unit, and in case that the dsp 21 actively needs to send the log information to the application processor 20 or the storage unit in the buffer is already occupied, the dsp 21 actively sends a message to the application processor 20 to notify the application processor 20 to read the log information. During the reading process, the dsp 21 may actively update the index of the memory cell to record the condition that the log information is read. The purpose of the recording may be to delete the log file being read, or to prevent repeated reads. Specifically, after the peripheral chip is initialized, any log information (log) is printed, and the log information (log) is stored in a log buffer (log buffer) temporarily by default, each log (log) occupies the space of one storage unit (slot), and the slot index is used for recording that the current log records the number of slots. When the peripheral chip actively wants to send the log to the AP or the slot in the log buffer is used up, the peripheral chip actively sends a message to the AP to inform the AP to read the log. After the AP reads, the peripheral chip records the read slot index into the previous slot index variable to mark the position where the AP reads. For example, if the index is 5, the AP is notified to read, and after reading, the peripheral chip writes 5 into the previous slot index variable, so as to mark the log information read by the AP into the 5 th slot. Subsequently, after writing a log into the log buffer by the peripheral chip, taking the remainder of the value of the total number of the storage units (slot N) through the slot index to determine that the written log is temporarily stored by using the several slots, and adding 1 to the slot index to prepare for the next written log. For example, there are 10 slots in total, then slot N is 10. And the current slot index is 6, after a log is written in, the current slot index takes the remainder of the slot N, the slot N is stored in the 6 th slot, and the value of the slot index is added with 1 to take 7. Thus, when the log is written next time, the 7 th slot can be determined to be used for temporarily storing the log written next time by taking the remainder. The present mechanism also supports the AP to actively read the log on the DSP side as well.

In this embodiment, the peripheral chip is a digital signal processing chip, and may be configured to process an audio signal, and the log information is a log file. In other embodiments, the peripheral chip may be other small chips that need to interact with the application processor.
Referring to step S50, the peripheral chip internally buffers the log information. In this embodiment, in order to ensure that there is enough space for storing log information, a buffer area including a plurality of storage units (slots) is provided in the peripheral chip for temporarily storing the log information, and the application processor also allocates a corresponding buffer area from the memory of the application processor. In this embodiment, the buffer structures respectively disposed in the digital signal processing chip and the application processor can be referred to fig. 2 of the previous embodiment. A buffer 211(log buffer) including a plurality of memory cells for storing a log file may be opened up in the SRAM in the digital signal processing chip 21. The dsp chip 21 reports the setting rule of the buffer 211 to the application processor 20, and the application processor 20 also allocates a buffer from the memory of the application processor 20 for storing the log file from the dsp chip 21.
Referring to step S51, the application processor actively initiates a request to read log information. In this embodiment, referring to fig. 3 of the previous embodiment, the communication mode between the dsp chip 21 and the control channel of the application processor 20 is mainly implemented by mailbox hardware. The request to read the log file is initiated actively by the application processor 20. The application processor 20 actively sends a read request to the digital signal processing chip 21 via the mailbox.
Referring to step S52, the peripheral chip uploads the log information to the application processor through a data channel between the peripheral chip and the application processor. In this embodiment, the communication mode of the digital signal processing chip 21 and the data channel of the application processor 20 can be referred to as shown in fig. 4 of the previous embodiment. The communication mode of the data channel between the digital signal processing chip 21 and the application processor 20 is also that the digital signal processing chip 21 notifies the application processor 20 through the mailbox, the buffer address and size on the digital signal processing chip 21 side, and the application processor 20 directly reads and writes the data with the specified address size in the SRAM on the digital signal processing chip 21 side through the SPI2 APB. SPI2APB refers to the connection mode of the Spi bus and the APB bus.
Referring to step S53, the peripheral chip marks the uploaded log information. In this embodiment, further, in order to ensure that the log file is not repeatedly read and written, the dsp 21 may establish a slot index (slot index) to record the occupation of the current log file to the storage unit, and when the dsp 21 actively needs to send the log file to the application processor 20 or the storage unit in the buffer is already occupied, the dsp 21 actively sends a message to the application processor 20 to notify the application processor 20 to read the log file. During the reading process, the dsp 21 may actively update the index of the storage unit to record the condition that the log file is read. The purpose of the recording may be to delete the log file being read, or to prevent repeated reads.
