Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The power consumption of the logic gate consists of dynamic power consumption and static power consumption, wherein the dynamic power consumption is generated by the turnover of a transistor in the logic gate, and the power of the dynamic power consumption can be expressed as the following relation (1):
wherein: alpha represents an activity factor, which is the probability that the logic gate output jumps from 0 to 1, or from 1 to 0; c represents the load capacitance of the logic gate; v represents the operating voltage of the logic gate; f represents the clock frequency.
The transistor toggles when the output of the logic gate at the previous input is opposite to the output at the current input. For example, for a NAND gate, the previous input is 00, and when the current input is 11, the NAND gate output transitions from 1 to 0. Thus, it is known that the dynamic energy consumption of a logic gate is not only related to the current input but also to the previous input.
Further, the static power consumption of the logic gate is generated by the transistor leakage current, and the leakage current is only related to the current input of the logic gate. The static energy consumption ratio of the logic gate with the gate size of 7nm of the transistor is over 40%. Considering that the gate size of the transistor is continuously reduced in the future, the static energy consumption ratio of the logic gate is gradually increased, and the traditional method for calculating the dynamic energy consumption according to the turnover rate cannot accurately calculate the whole energy consumption of the logic gate under the condition that the dynamic energy consumption is dominant.
Accordingly, an embodiment of the present invention provides a method for calculating a single running average energy consumption of a logic gate, as shown in fig. 1, including the following steps:
step 101: and acquiring a first input state set of the logic gate to be calculated in a first moment and a second input state set of the logic gate to be calculated in a second moment based on the input data sequence.
Wherein, for any N-input logic gate, the number of the input data sequence is 1,2, N;
the second time is the next time adjacent to the first time, namely the first input state set is the previous input state set of the logic gate to be calculated, and the second input state set is the current input state set of the logic gate to be calculated
Specifically, the number of all possible input states of the logic gate to be calculated, i.e. the input state k in the first set of input states i I=1, 2,..the number of m, or the second set of input states inputs state k j J=1, 2, the number of m is as follows: m=2 n 。
Step 102: a first relationship is determined based on the first set of input states and the second set of input states.
The first relation reflects the relation between the conversion of the input state of the logic gate to be calculated and the energy consumption.
In particular, the power consumption of the logic gate is not only related to the current input but also to the previous input. Therefore, by combining the first input state set and the second input state set, the corresponding relation between the input state of the logic gate to be calculated and the energy consumption can be obtained.
Step 103: a second relationship is determined based on the input data sequence, the first set of input states, and the second set of input states.
Wherein the second relation reflects a transition probability of an input state of the input data sequence.
Specifically, in combination with the input data sequence, the first input state set and the second input state set, a transition probability corresponding to an input state of the logic gate to be calculated may be obtained, and further, the transition probability of the input state may reflect a distribution characteristic of the input data sequence.
Step 104: and obtaining the average energy consumption of the logic gate to be calculated in the single operation time through a preset first calculation method based on the first relation and the second relation.
Specifically, a calculation relation of the average energy consumption of the logic gate in a single operation time can be obtained according to the first relation and the second relation, and further, the average energy consumption of the logic gate to be calculated in the single operation time can be obtained according to the calculation relation.
The method for calculating the single-operation average energy consumption of the logic gate, provided by the embodiment of the invention, combines the distribution characteristics of the input data sequences with the relations between the different input states of the logic gate and the energy consumption, can obtain the calculation method of the single-operation average energy consumption of the logic gate, is not influenced by the change of the input data sequences, can update the single-operation average energy consumption of the logic gate in real time only by counting the distribution characteristics of the data sequences in real time, is closer to the physical principle behind the logic operation compared with the method for directly measuring the energy consumption, does not relate to the physical factors such as the process, the material and the like of the logic gate, and greatly simplifies the flow and the step for analyzing the single-operation average energy consumption of the logic gate. Therefore, by implementing the invention, the result can be accurately calculated no matter what the static energy consumption ratio is.
As an alternative implementation of the embodiment of the present invention, step 102 includes: determining at least one energy consumption generated by the logic gate to be calculated in a single operation time based on the first input state set and the second input state set; the first relation is determined based on each of the energy consumptions.
Specifically, according to the description of step 102, the first relation reflects the relation between the input state of the logic gate to be calculated and the energy consumption, that is, the first relation is shown in the following relation (2):
wherein the elements in the matrixRepresenting the previous input of the logic gate to be calculated as k i Current input k j If so, the logic gate consumes energy generated in a single operation time.
As an optional implementation manner of the embodiment of the present invention, before step 103, the method further includes:
and acquiring a preset probability value of a high level in each input data in the input data sequence and a number value of the input high level of each input data in the input state of the first moment and the second moment respectively.
Specifically, for N-input logic gates, the input data sequence is numbered 1,2, according to the description of step 101, N, further, in the embodiment of the present invention, probability values of high levels (logical value is "1") in the input data sequence are set to be respectivelyAnd the data sequences are independent of each other in both time and space.
Further, the input data sequence 1,2 is acquired, N is at k i And k j High level number n in two inputs 1 ,n 2 ,...,n N 。
As an alternative implementation of the embodiment of the present invention, step 103 includes: obtaining at least one input state transition probability of the logic gate to be calculated through a preset second calculation method based on the first input state set, the second input state set, each preset probability value and each numerical value; the second relation is determined based on each of the input state transition probabilities.
Specifically, the preset second calculation method is shown in the following relation (3):
wherein:representing the previous input as k i Current input k j If yes, the input state transition probability of the logic gate is to be calculated.
Further, based on each input state transition probability determined by the above-described relation (3), a second relation is determined, as shown in the following relation (4):
further, according to the above-mentioned relational expressions (2) and (4), a calculation relational expression of average energy consumption of the logic gate in a single operation time is obtained, as shown in the following relational expression (5):
wherein: w represents the average power consumption of the logic gate during a single operation time.
The conventional application of the input probability of the circuit aims at calculating the output probability of the circuit, namely, calculating the output probability distribution of the circuit through the input probability vector of the circuit, the circuit topology structure and the corresponding probability transition matrix. Unlike the conventional method, which applies to input probability, the present invention focuses on a single logic gate, analyzes the transition probability of the previous input and the current input of the logic gate, instead of a single current input, and aims to analyze the average energy consumption of a single operation of the logic gate according to the relationship between the input transition probability and the energy consumption, unlike the method, which calculates the output probability of the logic gate according to the input probability of the logic gate only (without considering the transition between the inputs), and the present invention is applicable to any n-input logic gate.
In one example, taking a two-input NAND gate as an example, the average energy consumption of the NAND gate in a single operation time is calculated.
First, according to the above-mentioned relation (2), the relation between the conversion of the input states of the two-input nand gate and the energy consumption is obtained, as shown in the following relation (6):
wherein: e (E) NAND Representing the previous input as 00/01/10/11 and 00/01/10/11, the two-input nand gate consumes energy during a single operation.
Next, according to the above-mentioned relation (4), the transition probability of the input state of the two-input nand gate is obtained as shown in the following relation (7):
wherein: t (T) NAND Representing the transition probability of the input state of the two-input nand gate when the previous input is 00/01/10/11 and the current input is 00/01/10/11.
Finally, based on the above relation (5), by combining the above relations (6) and (7), the average energy consumption of the two-input nand gate in a single operation time can be obtained, as shown in the following relation (8):
