[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0024] Please also refer to Figure 2 and Figure 3 , Figure 2 A flowchart illustrating a RAM reading and writing method according to an embodiment of the present invention is shown; Figure 3 A schematic diagram of the read and write states of a RAM read and write method according to an embodiment of the present invention is shown.
[0025] like Figure 2 As shown, this embodiment provides a RAM reading and writing method, which includes:
[0026] S110, sending input data to be written into RAM.
[0027] For example, in Figure 3 In the embodiment, the input data sent to be written into the RAM may include eight groups of data from data0 to data7, but the present invention is not limited thereto and may also include multiple groups of data of other numbers.
[0028] S120 , detecting the input data, obtaining the number of consecutive repetitions of data in multiple groups of data, and generating index data.
[0029] For example, in Figure 3 In the example, for the eight data sets from data0 to data8 in the input data, the data characteristics stored in the RAM are as follows: data0 and data1 are the same data, data3, data4 and data5 are the same data, data6 and data7 are the same data, data2 and the adjacent data1 or data3 are different data, and data6 and the adjacent data5 are different data. This is only used to illustrate the embodiment and is not a specific limitation on the data characteristics stored in the RAM. Thus, Figure 3 The number of consecutive repetitions of data in the example data sets is 2, 1, 3 and 2, respectively, resulting in Figure 3 The index data shown.
[0030] S130 , writing the index data and a group of data corresponding to the index data into the RAM address according to the write enable signal.
[0031] For example, in Figure 3 In the example, the index data is 2, 1, 3 and 2. The first 2 in the index data can correspond to data0 and data1, so a write address can be generated. According to the write enable signal, the first 2 in the index data and a group of data data0 or data1 corresponding to the 2 are written to RAM address 0. Similarly, the 1 in the index data and a group of data data2 corresponding to the 1 are written to RAM address 1. The 3 in the index data and a group of data data3, data4 or data5 corresponding to the 3 are written to RAM address 2. The second 2 in the index data and a group of data data6 or data7 corresponding to the 2 are written to RAM address 3. Figure 3 and Figure 1 By comparison, it can be seen that the prior art generates eight write addresses when storing data in RAM and performs eight RAM write operations, while the present embodiment generates four write addresses when storing data in RAM and performs four RAM write operations. Thus, the generation of RAM write addresses can be effectively reduced, the number of write address operations on RAM can be reduced, and power consumption can be reduced.
[0032] S140 , reading out the index data in the RAM address and a group of data corresponding to the index data according to the read enable signal.
[0033] For example, in Figure 3In the data stored in RAM, according to the read enable signal, the data can be read out. That is, according to the read enable signal, the first 2 in the index data in RAM address 0 and a group of data data0 or data1 corresponding to the 2 can be read out, the 1 in the index data in RAM address 1 and a group of data data2 corresponding to the 1 can be read out, the 3 in the index data in RAM address 2 and a group of data data3, data4 or data5 corresponding to the 3 can be read out, and the second 2 in the index data in RAM address 3 and a group of data data6 or data7 corresponding to the 2 can be read out. Figure 3 and Figure 1 By comparison, it can be seen that the prior art generates eight read addresses when reading data from the RAM and performs eight RAM read operations, while the present embodiment generates four read addresses when reading data from the RAM and performs four RAM read operations. Thus, the generation of RAM read addresses can be effectively reduced, the number of read address operations on the RAM can be reduced, and power consumption can be reduced.
[0034] S150: Generate output data according to the index data and a group of data corresponding to the index data.
[0035] For example, in Figure 3 In the example, according to the first 2 in the index data read from RAM address 0 and the corresponding data set data0 or data1, the data set can be repeatedly output twice to obtain data0 and data1 in the output data; according to the 1 in the index data read from RAM address 1 and the corresponding data set data2, the data set can be output only once to obtain data2 in the output data; according to the 3 in the index data read from RAM address 2 and the corresponding data set data3, data4, or data5, the data set can be repeatedly output three times to obtain data3, data4, and data5 in the output data; according to the second 2 in the index data read from RAM address 3 and the corresponding data set data6 or data7, the data set can be repeatedly output twice to obtain data6 and data7 in the output data. Thus, the final output data is data0, data1, data2, data3, data4, data5, data6, and data7, which are the same as the input data data0 to data7.
[0036] Therefore, the RAM read and write control method provided in this embodiment can obtain the number of consecutive repetitions of data in multiple groups of data according to the characteristics of the data stored in the RAM, generate index data, and write the index data and a group of data corresponding to the index data into the RAM address together according to the write enable signal; read out the index data and a group of data corresponding to the index data in the RAM address according to the read enable signal; generate output data according to the index data and a group of data corresponding to the index data, which can effectively reduce the generation of RAM write addresses and read addresses, reduce the number of operations of the read and write addresses on the RAM, and reduce power consumption.
[0037] Optionally, obtaining the number of consecutive repetitions of data in multiple groups of data includes: performing data comparison to obtain the first group of data and the last group of data in which data appear consecutively; and obtaining the number of consecutive repetitions of data in multiple groups of data based on the sorting positions of the first group of data and the last group of data in which data appear consecutively.
[0038] For example, in Figure 3 , perform data comparison; the first group of data data0 and the last group of data data1 that appear continuously can be obtained. According to the sorting positions of data0 and data1, the number of data that appear continuously in multiple groups of data can be obtained as 2; the first group of data data2 and the last group of data data2 that appear continuously can be obtained. According to the sorting positions of data2 and data2, the number of data that appear continuously in multiple groups of data can be obtained as 1; the first group of data data3 and the last group of data data5 that appear continuously can be obtained. According to the sorting positions of data3 and data5, the number of data that appear continuously in multiple groups of data can be obtained as 3; the first group of data data6 and the last group of data data7 that appear continuously can be obtained. According to the sorting positions of data6 and data7, the number of data that appear continuously in multiple groups of data can be obtained as 2.
[0039] Optionally, performing data comparison to obtain the first and last sets of data that appear repeatedly includes: sequentially comparing two adjacent sets of data from the plurality of sets of data, and obtaining the first and last sets of data that appear repeatedly according to the comparison result.
[0040] For example, in Figure 3, two adjacent groups of data in the multiple groups of data are compared in sequence, and the comparison result is that data0 and data1 are the same data, data1 and data2 are different data, data2 and data3 are different data, data3 and data4 are the same data, data4 and data5 are the same data, data5 and data6 are different data, and data6 and data7 are the same data; thus, the first group of data data0 and the last group of data data1 that appear continuously can be obtained, the first group of data data2 and the last group of data data2 that appear continuously can be obtained, the first group of data data3 and the last group of data data5 that appear continuously can be obtained, and the first group of data data6 and the last group of data data7 that appear continuously can be obtained.
[0041] Optionally, performing data comparison to obtain the first set of data and the last set of data that appear repeatedly includes: performing data comparison to obtain the first set of data; comparing the first set of data with subsequent data in sequence until the two sets of data are different, and then determining the last set of data.
[0042] For example, in Figure 3 , data comparison is performed to obtain the first group of data data0, and data0 is compared with subsequent data in sequence until data0 and data2 are compared to obtain two groups of data that are different. It is determined that the last group of data when the first group of data data0 is data1, then the first group of data data0 and the last group of data data1 that appear continuously can be obtained; similarly, the first group of data data2 and the last group of data data2 that appear continuously can be obtained, the first group of data data3 and the last group of data data5 that appear continuously can be obtained, and the first group of data data6 and the last group of data data7 that appear continuously can be obtained.
[0043] Optionally, performing data comparison includes: when comparing two sets of data, comparing whether the numbers corresponding to the same digits are the same, and repeating until the numbers corresponding to each digit are compared. For example, when comparing data0 and data1, comparing whether the numbers corresponding to the same digits are the same, and repeating until the numbers corresponding to each digit are compared, it can be found that the numbers corresponding to all digits are the same, and data0 and data1 can be determined to be the same data; when comparing data1 and data2, comparing whether the numbers corresponding to the same digits are the same, and repeating until the numbers corresponding to each digit are compared, it can be found that the numbers corresponding to at least one digit are different, and data1 and data2 can be determined to be different data.
[0044] Optionally, when comparing two sets of data, the numbers corresponding to the same digits are compared to see if they are the same, and repeating until the numbers corresponding to each digit are compared, including: setting the digit length of one of the two sets of data to the count number; comparing the numbers corresponding to the same digits to see if they are the same, and repeating until the numbers corresponding to each digit are compared, and reducing the count number by one each time a comparison operation corresponding to a digit is performed, and stopping the comparison operation when the count number reaches zero. For example, when comparing data0 with data1, the digit length of data0 can be set to the count number; compare whether the numbers corresponding to the same digits are the same, and repeat until the numbers corresponding to each digit are compared, and the count number is reduced by one each time a comparison operation corresponding to a digit is performed, until the comparison operation is stopped when the count number reaches zero, it can be obtained that the numbers corresponding to all digits are the same, and it can be determined that data0 and data1 are the same data; when comparing data1 with data2, the digit length of data1 can be set to the count number; compare whether the numbers corresponding to the same digits are the same, and repeat until the numbers corresponding to each digit are compared, and the count number is reduced by one each time a comparison operation corresponding to a digit is performed, until the comparison operation is stopped when the count number reaches zero, it can be obtained that the numbers corresponding to at least one of the digits are different, and it can be determined that data1 and data2 are different data.
[0045] Optionally, according to a write enable signal, the index data and a group of data corresponding to the index data are written together to the RAM address, including: setting a group of data corresponding to the index data as the first group of data or the last group of data that appears continuously and repeatedly; according to a write enable signal, the index data and a group of data corresponding to the index data are written together to the RAM address.
[0046] For example, in Figure 3 In the example, the group of data corresponding to 3 in the index data can be set to the first group of data data3 or the last group of data data5 that appear continuously; according to the write enable signal, the 3 in the index data and the data3 or data5 corresponding to the 3 are written into the RAM address together.
