[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0026] As mentioned above, when processing the transmission data, the prior art must re-traverse all the data in the access data area to complete the statistical processing of the data. This process greatly occupies the computer's data processing time, resulting in reduced processing efficiency.
[0027] Based on this, the concept of the present invention is to set up a statistical unit on the bus to complete statistical calculations on data while transmitting data, thereby reducing the CPU's repeated access to original data to calculate this information and reducing the load on the CPU and the bus.
[0028] The specific implementation of the above concept is described below.
[0029] Please refer to Figure 1 , an embodiment of the present invention provides a method for collecting data of a SOC bus, the method comprising:
[0030] Step 100, initializing the SOC bus and the preset statistical unit according to the transmission request to perform data transmission;
[0031] Step 102, using the statistical unit to calculate statistical information of data transmitted within a specific address segment of the bus;
[0032] Step 104, transmitting the statistical information to the data channel output port, so as to directly use the statistical results for further processing.
[0033] In the embodiment of the present invention, firstly, the data in the data area is transmitted to the processing area through the SOC bus according to the request instruction; the preset statistical unit is called according to the statistical instruction to perform statistical calculation on the transmitted data; and the statistical calculation result is transmitted to the processing area according to the processing instruction, so as to directly use the statistical result for further processing. Through this method, the statistical processing of the transmitted data can be completed while the data is being transmitted, avoiding the data access load caused by repeated access to the processing area, and greatly improving the data processing efficiency.
[0034] Described below Figure 1 How the various steps are performed.
[0035] First, with respect to step 100 , the SOC bus and a preset statistical unit are initialized according to a transmission request to perform data transmission.
[0036] The processing of audio and video data generally needs to be transferred from data area A to data processing area B for further processing, and simple statistical calculations are performed before processing. For example, before IFFT of speech noise reduction processing, it is necessary to first determine the maximum value of the processed data. If the maximum value of the data is less than a certain value, the data to be processed will be amplified and then the IFFT process will be performed. That is, before performing IFFT on the data in area B, the data in area B must be accessed and read again to obtain the maximum value, which causes multiple repeated accesses of the CPU, affecting the processing efficiency.
[0037] Therefore, this embodiment adds a statistical unit to the bus to complete the transmission and perform statistics on the data, such as Figure 2 and Figure 3 As shown, the statistical unit can be mounted on the global bus or the local bus. In order to implement this design, the bus needs to be initialized before transmission.
[0038] Since each address on the bus corresponds to transmission data, it is necessary to determine in advance which address segments need to be counted, that is, determine the target address segment and data type of the data in advance, and turn on the clock gating of the corresponding statistical unit according to the statistical requirements. Each statistical unit has a separate enable and gating design, so that the corresponding unit can be turned on as needed, and unnecessary units will not work to save power consumption.
[0039] by Figure 4 Taking the example shown in the figure, the address segment to be counted is 0x0400_0000:0x0400_0fff, that is, the starting address is 0x0400_0000; the end address is 0x0400_0fff; the data type can be read data or write data, that is, both input and output can be counted. Figure 4 Take reading data as an example; then turn on the corresponding clock gating to complete the initialization process.
[0040] Then, with respect to step 102, a statistical unit is used to calculate statistical information of data transmitted within a specific address segment of the bus.
[0041] In the implementation of the present invention, the calculation module of the statistical unit includes calculating the maximum value, the minimum value, the cumulative sum, the absolute value cumulative sum, the average value, the absolute value average value, the square sum and the cube sum, etc. These calculation modules can be adjusted according to actual needs, and the corresponding modules work according to clock gating control, which will not be described in detail here.
[0042] In an embodiment of the present invention, the calculation process of statistical information includes using a statistical unit to monitor the transmission data of the target address segment; capturing the corresponding transmission data in the target address segment according to the monitoring results; using the statistical unit to perform statistical calculations on the captured transmission data; when calculating, it is necessary to pre-process the captured transmission data according to the bus communication protocol; then execute the statistical function of the statistical unit on the pre-processed data to obtain the calculation results; finally, determine whether the statistics of the transmission data of all buses are completed, and if so, end the statistics and output the statistical information.
[0043] Specifically, the same Figure 4 For example, when the address: 0x400_0d14 to 0x400_0d20 is monitored on the bus, since this segment belongs to a segment in the target address segment, the data in this segment address is captured: 0x01_01_01_01, 0x02_02_02_02, 0x03_03_03_03 and 0x04_04_04_04.
[0044] Furthermore, the communication protocol adopted in this embodiment is the AHB protocol, so htrans is first delayed by one beat to align with the data hrdata in timing; then the valid number transmitted on the data bus hrdata is selected according to htrans for statistical calculation: dma_sum<=dma_sum+hrdata[31:24]+hrdata[23:16]+hrdata[15:8]+hrdata[7:0]; finally, the above steps are repeated until all buses complete data transmission. The specific implementation code of this step is as follows Figure 5 shown.
[0045] It is understandable that when different communication protocols are selected, the statistical process of data within the statistical unit will also be different. These can be adjusted by relevant technical personnel according to actual needs and will not be elaborated here.
[0046] With respect to step 104 , the statistical information is transmitted to the data channel output port so as to directly utilize the statistical results for further processing.
[0047] In an embodiment of the present invention, after the data statistics are completed, the address of the statistical information in the statistical unit can be accessed according to the processing instruction issued by the processing module to transmit the statistical information through the data channel output port; when the statistical information transmission is completed, the clock gating is adjusted according to the processing instruction to close the statistical unit.
[0048] At this point, statistical processing is completed while data is being transmitted, which reduces the load on the CPU and bus and improves data processing efficiency.
