本发明属于人工智能技术领域，尤其涉及一种定制数据流硬件模拟仿真方法、装置、设备及存储介质。
背景技术
在人工智能领域的集成电路设计中，验证所占据的时间周期甚至超过了设计，达到50％以上。对于涉及软硬件的协同工作的产品，验证变得尤为重要和复杂。定制数据流架构人工智能***的设计涉及软硬件的紧密合作，由于硬件和软件设计是分开的，如果完全等两边分开开发完再合并验证，将会使得整个开发流程冗长而繁杂，期间上层软件不知道如何控制硬件，下层硬件也无法得到准确的数据进行测试验证。
现阶段在工业界广泛应用的验证方法有：基于验证平台或软件的仿真验证，形式化验证，软硬件协同验证。其中以仿真验证最为广泛，也是集成电路设计中必不可少的一环。通过建立测试用例，检查RTL硬件设计在特定的激励下是否会产生相应的响应。
随着硬件设计的规模越来越大，构建***级仿真环境的开销越来越大。而且仿真的本质导致了硬件仿真的时间在硬件设计具有一定规模时，成为验证设计的瓶颈。硬件设计具有一定规模时，硬件仿真的时间极长。
完整的硬件***级的验证离不开软件的支持。在数据流人工智能加速芯片的工作流程中，硬件***需要提供神经网络每一层的输入数据，才能进行计算。而若这些数据不能及时而正确地产生并在***仿真时送给硬件，会给硬件的开发带来很大的麻烦，降低开发的效率。
因此，现有的硬件***级的仿真方法存在仿真速度低，导致定制数据流产品开发效率低的问题。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
现有的硬件***级的仿真方法存在仿真速度低，导致定制数据流产品开发效率低的问题。本发明由于在C语言环境中模拟定制数据流硬件的工作流，将 ***级的仿真验证中硬件部分仿真通过C语言环境进行实现，软件部分与硬件部分可以在同一环境中形成数据流的计算，便于开发过程中软件部分与硬件部分的协调，提高开发效率。
如图1所示，图1为本发明实施例提供的一种定制数据流硬件的架构图，架构103与片外存储模块(DDR)101以及处CPU102通过互连进行连接，架构103包括：第一存储模块104、全局数据流网络105以及数据流引擎106，上述第一存储模块104通过互连连接上述片外存储模块101的同时，还通过互连连接上述全局数据流网络105，上述数据流引擎106通过互连连接上述全局数据流网络105以使上述数据流引擎106可以实现并行或串行。上述的数据流引擎106可以包括：计算核(或称为计算模块)、第二存储模块108以及局部数据流网络107，计算核可以包括用于计算的内核，比如卷积核109、池化核110以及激活函数核111等，当然，还可以包括除示例卷积核109、池化核110以及激活函数核111外的其他计算核，在此并不做限定，也可以包括在神经网络中所有用于计算的内核。上述的第一存储模块104与上述的第二存储模块108可以是片上缓存模块，也可以是DDR或高速DDR存储模块等。上述的数据流引擎106可以理解为支持数据流处理的计算引擎，也可以理解为专用于数据流处理的计算引擎。
上述的数据流架构可以是在FPGA可编程门阵列上进行定制。
如图2所示，为根据本申请的一种定制数据流硬件模拟仿真方法所提供的一个实施例的流程图。上述的定制数据流硬件模拟仿真方法，包括步骤：
S101，获取定制数据流硬件参数以及待仿真数据。
其中，上述的定制数据流硬件参数包括寄存配置参数、神经网络结构图与神经网络参数。
上述的寄存配置参数用于在C语言环境的存储器中开辟对应的存储区，以行成对应的寄存地址。
上述的神经网络结构图可以是识别类的神经网络结构图，比如人脸识别，车辆识别等，也可以是检测类的神经网络结构图，比如物体检测，车辆检测等。
上述的神经网络结构图可以理解为神经网络结构，进一步的，可以理解为用于各类神经网络模型的神经网络结构。上述的神经网络结构是以层为计算单 元的，包含且不限于：卷积层、池化层、ReLU、全连接层等。
神经网络结构图包括不同神经网络层间的串行关系，比如卷积层、偏置层、池化层等神经网络层之间的串行关系。
上述的神经网络参数是指的神经网络结构中的每一层对应的参数，可以是权重参数、偏置参数等。上述的各类神经网络模型可以是预先训练好的对应神经网络模型，由于神经网络模型是预先训练好的，其神经网络参数的属性也是训练好的，因此，在仿真软件中配置好的神经网络可以根据配置的神经网络参数直接使用，不需要再对神经网络进行训练，根据该预先训练好的神经网络模型，可以通过神经网络结构图以及参数进行统一描述。
上述获取神经网络结构图以及神经网络参数可以是在本地进行获取，也可以是云服务器上进行获取，比如：上述的神经网络结构图以及神经网络参数可以成套的存储在本地，在使用时自动进行选择或者用户进行选择，或者是将神经网络结构图以及神经网络参数上传到云服务器中，在使用时通过网络将云服务器中的神经网络结构图以及神经网络参数下载下来。
S102，根据所述寄存配置参数在C语言环境中配置对应的寄存地址，并将待仿真数据、神经网络结构图与神经网络参数寄存到对应的寄存地址。
其中，上述的寄存配置参数为步骤S101中获取到的寄存配置参数，该寄存配置参数包括配置多少个寄存地址、以及对应寄存地址的大小。每个寄存地址可以存储对应的数据，比如，配置一个寄存地址用于存储仿真数据，配置一个寄存地址用于存储一个神经网络层的参数等，在需要时，从寄存地址中直接读取对应的数据即可。
另外，寄存地址也用于存储对应的计算结果，比如，卷积神经网络层对应的寄存地址存储有对应的权重参数之外，还用于在完成卷积计算后，存储对应的卷积结果。
在一个实施例中，上述寄存配置参数包括全局流配置参数与局部流配置参数，上述神经网络参数包括不同神经网络层参数。
分别配置所述待仿真数据以及神经网络结构图对应的全局流寄存地址。
由于待仿真数据以及神经网络结构图为全局数据，可以分别为待仿真数据以及神经网络结构图配置不同的全局流寄存地址。
配置所述不同神经网络层参数对应的局部流寄存地址。
由于一个神经网络中存在多个神经网络层，每个神经网络层都需要有不同的配置参数进行计算实现，比如卷积层需要权重参数与输入数据进行计算，偏置层需要偏置参数与输入数据进行计算。
因此，可以根据不同神经网络层参数配置不同的局部流寄存地址，在计算不同神经网络层时，读取对应寄存地址的参数与输入数据进行计算。比如，在进行卷积计算时，读取对应卷积层权重参数所在的寄存地址中的权重参数，与输入数据进行计算。
上述的C语言环境中配置对应的寄存地址，可以是在C语言环境中比如电脑的硬盘中开辟对应的存储空间作为寄存地址，也可以是在C语言环境中配置好的虚拟存储空间中开辟对应的存储空间作为寄存地址。
S103，根据对应寄存地址中的神经网络结构图模拟构建对应的模拟神经网络。
神经网络结构图包括不同神经网络层间的串行关系，根据该串行关系，确定数据流在不同神经网络层间的数据流关系，从而构建得到对应的模拟神经网络，需要说明的是，上述的模拟神经网络为定制数据流模拟神经网络。
上述的不同神经网络层间的数据流关系用于描述数据的流向。
在一个实施例中，在存储有神经网络结构图的全局流寄存地址中读取对应的神经网络结构图。根据读取到的神经网络结构图，模拟构建对应的模拟神经网络。这样，在全局流寄存地址中的神经网络结构图可以实现复用。
S104，将对应寄存地址中的待仿真数据以及神经网络参数输入到模拟神经网络进行仿真计算，得到验证数据，并返回对应的寄存地址。
在存储有待仿真的寄存地址中读取出对应的待仿真数据，在经过模拟神经 网络的计算完成后，得到用以与真实硬件计算结果进行对比的验证数据。在计算完成后，将得到的验证数据写回对应的寄存地址，上层的软件可以从对应的寄存地址中读取该验证数据，提供给用户。
在一个实施例中，读取对应的全局流寄存地址中的所述待仿真数据。
将待仿真数据输入到上述的模拟神经网络中。
分别读取对应的局部流寄存地址中的每层神经网络层参数与对应的待仿真数据进行计算，得到每层神经网络层对应的层验证数据，并将每层神经网络层的层验证数据返回到对应的局部流寄存地址。这样，可以复用每层神经网络层对应的层验证数据。
在所有神经网络层计算完比后，得到模拟神经网络的验证数据，并将模拟神经网络的验证数据返回到对应的全局流寄存地址。
本发明实施例中，获取定制数据流硬件参数以及待仿真数据，定制数据流硬件参数包括寄存配置参数、神经网络结构图与神经网络参数，神经网络结构图包括不同神经网络层间的串行关系；根据寄存配置参数在C语言环境中配置对应的寄存地址，并将待仿真数据、神经网络结构图与神经网络参数寄存到对应的寄存地址；根据对应寄存地址中的神经网络结构图模拟构建对应的模拟神经网络，模拟神经网络包括不同神经网络层间的数据流关系，数据流关系根据串行关系得到；将对应寄存地址中的待仿真数据以及神经网络参数输入到模拟神经网络进行仿真计算，得到验证数据，并返回对应的寄存地址。由于在C语言环境中模拟定制数据流硬件的工作流，将***级的仿真验证中硬件部分仿真通过C语言环境进行实现，软件部分与硬件部分可以在同一环境中形成数据流的计算，便于开发过程中软件部分与硬件部分的协调验证，提高开发效率。
如图3所示，为根据本申请的另一种定制数据流硬件模拟仿真方法所提供的一个实施例的流程图。上述的定制数据流硬件模拟仿真方法，包括步骤：
S201，获取定制数据流硬件参数以及待仿真数据。
S202，根据所述寄存配置参数在C语言环境中配置对应的寄存地址，并将 待仿真数据、神经网络结构图与神经网络参数寄存到对应的寄存地址。
S203，根据对应寄存地址中的所述神经网络结构图模拟构建对应的模拟神经网络。
S204，对待仿真数据进行量化，得到8bit单元长度的待仿真数据。
其中，上述的量化为根据量化信息进行量化，上述的量化信息包括在上述的神经网络结构图中，上述的量化信息包括将数据量化为8bit单元长度的信息。
可以根据上述的量化信息将待仿真数据进行量化，将仿真数据量化为8bit数据等。
上述的量化可以是通过编译器进行完成。
具体的，可以通过公式r＝s×(q-z)进行计算，其中，r指的是浮点数值，就是用户输入的数据，q指的是量化后的数据，z是偏移值，s是缩放值，s和z是编译器产生的。
根据公式r＝s×(q-z)可得，量化后的数据为q＝r/s+z。
由于s和z是编译器产生的，r是用户输入的待仿真数据，所以通过编译器对输入的待仿真数据进行量化，得到量化后的仿真输入数据。
其中，经过量化后，得到的仿真输入数据与神经网络参数为同一数据类型。
需要说明的是，神经网络参数与待仿真数据不同，神经网络参数为硬件数据类型，即为整型数据类型，而待仿真数据为浮点数据类型。在经过编译器的量化后，待仿真数据变成仿真输入数据，与神经网络参数为同一数据类型。
进一步的，获取待仿真数据，并根据量化信息，将待仿真数据转换为8bit单元长度的待仿真数据，得到8bit单元长度的仿真输入数据。
其中，神经网络参数也是8bit单元长度的数据，神经网络参数包括权重参数及偏置参数。
S205，将8bit单元长度的待仿真数据输入到模拟神经网络中。
S206，在每层神经网络层计算得到层验证数据后，将上一神经网络层对应的层验证数据进行量化，得到8bit单元长度的层验证数据。
在上一神经网络层计算后，得到的层验证数据为int32的数据，在需要输入到当前神经网络层计算时，会将该int32的数据进行量化，得到8bit单元长度的层验证数据。
S207，将上一神经网络层对应的8bit单元长度的层验证数据输入到当前层神经网络层，计算完成后，将对应的层验证数据返回当前神经网络层对应的寄存地址。
上述的上一神经网络层为当前神经网络层的上一神经网络层。将每层神经网络层对应的层验证数据写回对应的神经网络层对应的寄存地址，比如，将卷积层计算得到的卷积结果写加存储有卷积参数的局部流寄存地址，这样，可以实现卷积参数的快速复用。
S208，在所有神经网络层计算完比后，得到模拟神经网络的验证数据，并将模拟神经网络的验证数据返回到与待仿真数据对应的全局流寄存地址。
当最后的神经网络层计算完成，说明仿真计算完成，得到对应待仿真数据的验证数据。验证数据用以与真实硬件计算结果进行对比。在计算完成后，将得到的验证数据写回对应的寄存地址，上层的软件可以从对应的寄存地址中读取该验证数据，提供给用户。
本发明实施例中，获取定制数据流硬件参数以及待仿真数据，定制数据流硬件参数包括寄存配置参数、神经网络结构图与神经网络参数，神经网络结构图包括不同神经网络层间的串行关系；根据寄存配置参数在C语言环境中配置对应的寄存地址，并将待仿真数据、神经网络结构图与神经网络参数寄存到对应的寄存地址；根据对应寄存地址中的神经网络结构图模拟构建对应的模拟神经网络，模拟神经网络包括不同神经网络层间的数据流关系，数据流关系根据串行关系得到；将对应寄存地址中的待仿真数据以及神经网络参数输入到模拟神经网络进行仿真计算，得到验证数据，并返回对应的寄存地址。由于在C语言环境中模拟定制数据流硬件的工作流，将***级的仿真验证中硬件部分仿真通过C语言环境进行实现，软件部分与硬件部分可以在同一环境中形成数据流 的计算，便于开发过程中软件部分与硬件部分的协调验证，提高开发效率。另外，由于将待仿真数据量化为与神经网络参数相同的硬件数据类型，在使用软件仿真时，使得仿真计算更贴近硬件计算的结果，且硬件数据类型的数据计算量小于浮点类型的计算量，还可以提高神经网络仿真的计算速度。整个计算流程更贴近硬件的计算模式，减少浮点计算中的不相关内容，便于硬件用作输出校验。同时，由于计算模式和操作模式和硬件一致，所以可以直接模拟硬件的最终计算结果。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，该计算机程序可存储于一计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，前述的存储介质可为磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)等非易失性存储介质，或随机存储记忆体(Random Access Memory，RAM)等。
