在处理器领域,目前主流的架构为x86与ARM架构,经过几十年的发展,现代的x86与ARM架构的架构文档长达几百数千页,且版本众多。一个主要的原因是因为其架构的发展的过程也伴随了现代处理器架构技术的不断发展成熟,并且作为商用的架构,为了能够保持架构的向后兼容性,其不得不保留许多过时的定义,或者在定义新的架构部分时为了能够兼容已经存在的技术部分,久而久之就变得极为冗长。然而,RISC-V作为一种指令集,与大多数指令集相比,RISC-V指令集可以自由地用于任何目的,允许任何人设计、制造和销售RISC-V芯片和软件。它同时兼顾数据的传输量和传输速度,是异构IoT时代绝佳的架构,由其衍化而来的一系列生态日趋完善。RISC-V优势还在于:开源,CPU设计成本低,通过协作在硬件中产生的任何创新都将创造巨大的经济效益;简单,基础指令集仅40多条,满足嵌入式及物联网对代码体积的高要求;灵活,预留大量的编码空间和4条用户指令,可用于扩展指令集。虽然RISC-V不是第一个开源指令集,但它具有重要意义,因为其设计使其适用于现代计算设备。设计者考虑到了这些用途中的性能与功率效率。该指令集还具有众多支持的软件,这解决了新指令集通常的弱点。
本申请的一个实施例中,如图1所示,提供了一种脉冲调制控制系统100,包括处理器10及脉冲调制接口模块20,其中,基于RISC-V开源指令集架构的所述处理器10用于接收用户操作指令,并基于操作指令生成数据信号;脉冲调制接口模块20与处理器10连接,用于接收数据信号,并基于数据信号输出预设波形。
上述实施例中的脉冲调制控制系统100中,通过设置基于RISC-V开源指令集架构的处理器10来接收用户操作指令,并基于操作指令生成数据信号,从而控制脉冲调制接口模块20输出预设波形。基于RISC-V开源指令集架构使得用户可以自定义操作,提高脉冲调制过程的效率和灵活度,同时实现功耗优化。
在其中一个实施例中,如图2所示,处理器10包括基础指令子模块11及扩展指令子模块12,其中,基础指令子模块11用于实现RISC-V标准定义的标准指令集;扩展指令子模块12用于实现用户定义的自定制指令集。
具体地,RISC-V架构相比其他成熟的商业架构的最大一个不同还在于它是一个模块化的 架构,在本申请中符合RISC-V ISA标准的CPU包括基础指令子模块11,该模块用于实现RISC-V标准定义的标准指令集,标准指令集包括RV32I、RV32E、RV64I及RV128I。其中,RV32I为32位整数指令集,RV32E为RV32I的子集,用于小型的嵌入式场景;RV64I为64位整数指令集,兼容RV32I,RV128I为128位整数指令集,兼容RV64I和RV32I;符合RISC-V ISA标准的CPU还包括扩展指令子模块12,用于实现用户定义的自定制指令集。RISC-V架构不仅短小精悍,而且其不同的部分还能以模块化的方式组织在一起,从而通过一套统一的架构满足各种不同的应用,这种模块化是x86与ARM架构所不具备的。RISC-V ISA开源意味着针对不同的应用场景均可创造相应的芯片架构,借助相应的定制化指令工具可以使应用加速更有效率,多核异构的特点也促进功耗优化。
在其中一个实施例中,自定制指令包括脉冲调制控制指令,脉冲调制控制指令用于生成控制脉冲调制参数的参数数据信号。
具体地,基于RISC-V开源指令集架构中扩展指令集,用户可以自定制指令,应用在脉冲调制技术中,用户可以根据需求,指定脉冲调制控制指令,脉冲调制控制指令用于生成控制脉冲调制参数的参数数据信号,脉冲调制参数包括脉冲长度、占空比、开始相位、波形等。
在其中一个实施例中,如图3和图4所示,脉冲调制接口模块20包括十六条脉冲调制通道,任一条脉冲调制通道包括寄存器组、计数器及方向控制器,其中,寄存器组与处理器连接,寄存器组用于接收并存放参数数据信号;计数器与寄存器组连接,用于获取开始信号及数据信号,基于开始信号及数据信号开始计数,并生成阶段信号;方向控制器与寄存器组及计数器均连接,用于获取数据信号及阶段信号,基于数据信号及阶段信号,输出预设波形。
具体地,所述脉冲调制接口模块20包括十六条脉冲调制通道PWM0、PWM1、PWM2……PWM15,每一条PWM通道包括寄存器组、计数器及方向控制器。通过寄存器组与处理器连接,用于接收脉冲调制控制指令并存放参数数据信号,经由计数器及方向控制器处理后,输出预设波形。
在其中一个实施例中,参数数据信号包括第一参数数据信号、第二参数数据信号、第三参数数据信号及第四参数数据信号;寄存器组包括脉冲波形控制位、起始相位控制位、占空比控制位及波形周期控制位,其中,脉冲波形控制位占1比特,用于存放第一参数数据信号;起始相位控制位占1个字节,用于存放第二参数数据信号;占空比控制位占1个字节,用于存放第三参数数据信号;波形周期控制位占2个字节,用于存放第四参数数据信号。
其中,阶段信号包括触发信号、第一阶段控制信号及第二阶段控制信号,计数器包括第一计数器、第二计数器及第三计数器,其中,第一计数器与起始相位控制位及方向控制器均连接,用于获取开始信号及第二参数数据信号数值,基于开始信号及第二参数数据信号数值开始计数,并生成触发信号及第一阶段控制信号;第二计数器与占空比控制位及第一计数器均连接,用于获取触发信号及第三参数数据信号数值,基于触发信号及第三参数数据信号数值开始计数,并输出第二阶段控制信号;第三计数器与脉冲波形控制位连接,用于获取第一参数数据信号数值,基于第一参数数据信号数值开始计时,并控制脉冲调制控制系统停止。
作为示例,如图5所示,通过RISC-V自定义指令集,定义一组脉冲调制控制指令 setPWMn(s,a,b,c),其中s,a,b,c为脉冲调制控制指令,用于生成控制脉冲调制参数的参数数据信号。a对应第一参数数据信号,用于控制预设波形的起始位置,b对应第二参数数据信号,用于控制预设波形的占空比,c对应第三参数数据信号,用于控制预设波形的波长,s对应第四参数数据信号用于控制预设波形,具体地,s为0时,生成上凸波形,s为1时,生成为下凹波形。通过设定指令参数s,a,b及c,即可生成对应参数数据的预设波形。而传统x86和ARM架构多指令实现脉冲调制,完成一个脉冲的输出需要5到10条指令,还需要占用处理器的进程。本发明使用自定义指令,配合PWM控制器,只需要一条指令即可完成一个脉冲生成,且不占用处理器进程。
作为示例,如图6所示,寄存器包括脉冲波形控制位、起始相位控制位、占空比控制位及波形周期控制位,寄存器用于存放参数数据信号,其中,脉冲波形控制位占1比特(1bit),用于存放第一参数数据信号a;起始相位控制位占1个字节(8bit),用于存放第二参数数据信号b;占空比控制位占1个字节(8bit),用于存放第三参数数据信号c;波形周期控制位占2个字节(16bit),用于存放第四参数数据信号s。计数器包括第一计数器、第二计数器及第三计数器。
具体地,当用户下达操作指令setPWMn(s,a,b,c)后,寄存器组读取数据参数a,b,c,s参数,并分别传给第一计数器、第二计数器、第三计数器及方向控制器,同时,开始信号被发给第一计数器,第一计数器和第三计数器同时开始计数,第一计数器的计数阶段输出第一阶段控制信号,控制方向控制器输出与s相同的逻辑电平,即s=0时,输出0,s=1时输出1。第一计数器计到a后,结束计数并输出触发信号,第二计数器开始计数。第二计数器的计数阶段输出第二阶段控制信号,控制方向控制器输出与s相反的逻辑电平,即s=0时,输出1,s=1时输出0。第二计数器计到b结束,方向控制器输出s相同的逻辑电平。第三计数器计到c计数整个计数周期,输出一个结束标志,表示完成操作指令setPWMn(s,a,b,c),并输出预设的波形。
在其中一个实施例中,预设波形包括凸波形及凹波形,方向控制器被配置为:
获取第一参数数据信号及第一阶段控制信号,基于第一参数数据信号及第一阶段控制信号生成凸波形或凹波形;
获取第一参数数据信号及第二阶段控制信号,基于第一参数数据信号及第二阶段控制信号生成凹波形或凸波形。
具体地,方向控制器基于第一参数数据信号及阶段控制信号控制输出脉冲的波形,其中,第一参数数据信号s存储在寄存器组的脉冲波形控制位中,阶段信号由计数器控制发出,作为示例,当第一参数数据信号s=0,且方向控制器获取到第一阶段信号时,方向控制器输出上凸波形;当第一参数数据信号s=0,且方向控制器获取到第二阶段信号时,方向控制器输出下凹波形;当第一参数数据信号s=1,且方向控制器获取到第一阶段信号时,方向控制器输出下凹波形;当第一参数数据信号s=1,且方向控制器获取到第二阶段信号时,方向控制器输出上凸波形。本申请通过设置基于RISC-V的参数指令,即可进行脉冲宽度调制控制,大大简化了脉冲宽度调制控制过程,且降低了成本。
在其中一个实施例中,如图7所示,脉冲调制控制系统100还包括接口控制器30及第一接口模块40,其中,接口控制器30与基础指令子模块11连接,用于执行标准指令集;第一接口模块40与接口控制器30连接,用于实现数据的传输及外接设备的控制。
具体地,第一接口模块可以为处理器常用的接口,用于执行除了脉冲调制控制之外的其他功能,接口控制器可以为I/O控制器。
在其中一个实施例中,如图8所示,第一接口模块包括UART接口、QSPI接口、I2S接口、I2C接口、GPIO接口及JTAG接口中至少一种。
具体地,UART为通用异步收发传输接口,QSPI为六线串行外设接口,I2S为集成电路内置音频总线,I2C为二线制同步串行总线,GPIO为通用型输入输出接口,JTAG为联合测试总线。它们通过一个I/O控制器,由RISC-V内核的普通指令集操作。而PWM接口组则由扩展指令集X配合实现波形发生器的操作。
本申请的另一方面提供一种脉冲调制控制装置,包括任一本申请实施例中的脉冲调制控制系统。
上述实施例中的脉冲调制控制装置,通过设置基于RISC-V开源指令集架构的处理器来接收用户操作指令,并基于操作指令生成数据信号,从而控制脉冲调制接口模块输出预设波形。基于RISC-V开源指令集架构使得用户可以自定义操作,提高脉冲调制过程的效率和灵活度,同时实现功耗优化。

步骤202:获取用户操作指令;
步骤204:基于RISC-V开源指令集架构的处理器基于用户操作指令生成数据信号;
步骤206:基于脉冲调制接口模块接收数据信号,根据数据信号输出预设波形。

作为示例,利用RISC-V内核可自定义指令集的特点,设计了一组专门用于PWM控制的指令setPWMn(s,a,b,c),其中s,a,b,c为脉冲调制控制指令用于生成控制脉冲调制参数的参数数据信号。a对应第一参数数据信号用于控制预设波形的起始位置,b对应第二参数数据信号用于控制预设波形的占空比,c对应第三参数数据信号用于控制预设波形的波长,s对应第四参数数据信号用于控制预设波形。具体地,s为0时,生成上凸波形,s为1时,生成为下凹波形。具体地,操作指令控制PWM生成的过程如图10所示,控制器执行setPWMn(s,a,b,c)指令,将s,a,b,c参数数据信号送至寄存组,经由计数器及方向控制器处理后,输出预设波形。
