Description
Technical Field
The present invention relates to the field of digital circuits, and in particular, to a fuzzy processing method, apparatus and storage medium for eliminating continuous bubbles.
Background
When chip technology is implemented, if the delay accuracy of the thermometer code is small, for example, only 1ps, the delay of the bypass is larger than the delay of the thermometer code unit in the process. When a problem occurs in a certain delay or delays of the thermometer code, one or more jumps occur in the middle of the thermometer code, which is called bubbles, and the schematic diagram is shown in fig. 1.
When this occurs, the result of direct decoding is incorrect, and the correct decoded value cannot be recovered, and blurring processing is required. The traditional fuzzy processing mode is to shift the output thermometer code by one bit right with the thermometer code or then decode. However, simply shifting the output thermometer code by one bit to the right or not very good for the problem of the bubbles, only the jump of the thermometer code under a single condition can be processed, and the bubbles continuously and intermittently can not be processed.
Disclosure of Invention
Aiming at the problems in the prior art, a fuzzy processing method for eliminating continuous bubbles, electronic equipment and a storage medium are provided. The decoding output is determined by judging the leftmost bit and the rightmost bit of the thermometer code and combining the right shift or the judging result, so that the influence of continuous bubbles can be effectively solved.
The technical scheme adopted by the invention is as follows: when a bubble appears in a thermometer code, combining the leftmost bit with the rightmost bit of the thermometer code, and if the combined data is 2' b00, directly obtaining a decoding result of 0; if the combined data is 2' b11, the decoding result is full scale; if the combined data is 2'b01 or 2' b10, the thermometer code is shifted one bit to the right and then is exclusive-or with the original thermometer code, and the output decoding value is determined according to the exclusive-or result.
As a preferred option, when the combined data is 2' b01, the full scale is output if the first 1 of the exclusive or result occurs at the position of full scale/-1 or to the left thereof, otherwise 0 is output.
Preferably, when the combined data is 2' b10, the position value of the first 1 in the exclusive-or result is taken as the decoding output.
As a preferable scheme, when outputting the decoded value according to the exclusive or result, it is classified into left decoding and right decoding; the decoded value is output according to the position where the first 1 appears from the left or from the right.
Preferably, when the combination is 2' b10, if left-to-right decoding is adopted, the position value of the first 1 from left to right in the exclusive-or result is outputted as the decoded data.
Preferably, when the combination is 2' b10, if right decoding is adopted, the position value of the first 1 from right to left in the exclusive-or result is outputted as the decoding.
As a preferred scheme, when the bubble appears on the left side of the thermometer code, the right decoding is selected, and when the bubble appears on the right side of the thermometer code, the left decoding is selected.
The invention also provides an electronic device which comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and is corresponding to the fuzzy processing method for eliminating continuous bubbles.
The invention also provides a computer readable storage medium, on which computer program instructions are stored, which when executed by a processor are used to implement the process corresponding to the above-mentioned fuzzy processing method for eliminating continuous bubbles.

Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar modules or modules having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the present application include all alternatives, modifications, and equivalents as may be included within the spirit and scope of the appended claims.
The thermometer code and the thermometer code are simply shifted one bit to the right and then are phase-shifted or the problem of the bubbles cannot be solved, only the jump of the thermometer code under the single condition can be processed, the bubbles continuously and alternately appear and the direct decoding result can be wrong, and therefore, the embodiment of the invention provides a fuzzy processing method for eliminating the continuous bubbles, and the influence of the continuous bubbles can be effectively eliminated by comprehensively determining the decoding output by combining the leftmost data and the rightmost data of the thermometer code with the right shift or the result. The specific scheme is as follows:
referring to fig. 1, in a fuzzy processing method for eliminating continuous bubbles, when a thermometer code appears a bubble, combining the leftmost bit and the rightmost bit of the thermometer code, if the combined data is 2' b00 (representing two binary 00), the decoding result is directly 0; if the combined data is 2' b11 (representing two-bit binary 11), the decoding result is full scale; if the combined data is 2'b01 (representing two-bit binary 01) or 2' b10 (representing two-bit binary 10), the thermometer code is shifted one bit to the right and then exclusive-or with the original thermometer code, and the output decoding value is determined according to the exclusive-or result.
In the present embodiment, when outputting the decoded value according to the exclusive or result, it is classified into left-decoding and right-decoding; the decoded value is output according to the position where the first 1 appears from the left or from the right.
When the bubble does not appear, the right shift is basically consistent with the left shift or with the direct decoding result; when there are different bubbles, the conventional method may not be able to handle the situation, but the method can extract useful information and allow the loop to converge effectively.
Referring to fig. 1, in this embodiment, when the combined data is 2' b01, if the first 1 of the exclusive or results occurs at the position of full scale/-1 or left thereof, then the full scale is output, otherwise 0 is output. For example, when the full scale is 10 bits, the full scale/2-1=4, assuming that the exclusive or result is 000101100, decoding from left and right, and decoding from left, that is, seeing from left to right, that the first 1 appears in the 4 th bit, outputting 10; the first 1 appears at bit 7 when seen from right decoding, i.e., from right to left, and then outputs 0. It can be seen that there is a certain difference between the actual decoding from the left and the actual decoding from the right, and the adjustment can be made according to the specific situation when the application is performed.
And when the combined data is 2' b10, the position value of the first 1 in the exclusive OR result is taken as the decoding output. For example, the full scale is 10 bits, assuming that the exclusive or result is 000010110, the first 1 appears at the 5 th bit when seen from left decoding, i.e., from left to right, so the output result from left decoding is 5; the first 1 appears at bit 8 as seen from right decoding, i.e., from right to left, so the output from right decoding is 8.
Meanwhile, the embodiment further describes a proposed method for eliminating continuous bubbles by taking a 10-bit thermometer code as an example.
If no bubble is present, the results of decoding from left and right are identical to those of direct decoding, as shown in the following table:
when 1 bubble appears in the adjacent 1 bit on the left, the method can basically recover, has the best decoding performance from the right, has a difference value of 2 bits from the left decoding, does not influence convergence, and is specifically shown in the following table:
when 1 bubble appears in the adjacent 1 bit on the right, the method can basically recover, has the best decoding performance from the left, has a difference value of 2 bits from the right, does not influence convergence, and is particularly shown in the following table:
when 1 bubble appears in the left adjacent 2 bits, the method can basically recover, has the best decoding performance from the right, has a difference value of 3 bits from the left decoding, does not influence convergence, and is specifically shown in the following table:
when 1 bubble appears in the adjacent 2 bits on the right, the method can basically recover, has the best decoding performance from the left, has a difference value of 3 bits from the right, does not influence convergence, and is particularly shown in the following table:
when 2 bubbles appear in the adjacent 1 bit on the left, the method can basically recover, has the best decoding performance from the right, has a difference value of 3 bits from the left decoding, does not influence convergence, and is specifically shown in the following table:
when 2 bubbles appear in the adjacent 1 bit on the right, the method can basically recover, has the best decoding performance from the left, has a difference value of 3 bits from the right, does not influence convergence, and is particularly shown in the following table:
/>
it can be seen that both left decoding and right decoding can be recovered, and the two can cope with different bubble conditions, and the functions are complementary; when the bubble appears on the left side, the right decoding is selected, and when the bubble appears on the right side, the left decoding is selected, so that the performance is better. In practical application, the mode of controlling fuzzy processing by FTDC_dec_mode can be designed, wherein 0 is not fuzzy processing, 1 is decoding from left, 2 is decoding from right, and most of the cases of bubbles (including continuous bubbles) can be processed without basically increasing area and delay.
