Description
相关申请数据
本申请根据35 U.S.C.§119(e)条款要求2004年10月12日申请的美国专利申请号60/618,269的优先权,题目为“在DSL系统中共享存储器及处理资源”,合并在此作为参考。
技术领域
本发明通常涉及通信系统。特别的,本申请的一个典型实施例涉及通信系统中的存储器共享。另一个典型实施例涉及通信系统中处理或编码资源的共享。
背景技术
本申请所引用的专利号为6,775,320和6,778,589的美国专利,记载了支持多应用和多成帧器/编码器/交织处理器FCI模块(一个FCI模块也被称为一个时延路径)的DSL系统。DSL系统执行不同需求,例如,数据率,延时(延迟),位误码率(BER),及其它类似的,的传输。例如,视频通常要求低BER(<1E-10)但是允许较高的时延(>20ms)。语音,另一方面,通常要求低时延(>1ms)但是允许BER(<1E-3)。
如美国专利6,775,320中所记载的,为了满足通信系统中不同应用的需求,可以使用不同的时延路径。因而,收发器必须支持多时延路径以支持如视频、因特网访问以及语音电话等不同应用。取决于应用的需求,收发器的每个包括成帧器、编码器和交织处理器模块的时延路径都具有不同性能。
发明内容
在一个收发器中实现多时延路径的困难之处在于,事实上时延路径是一个需要大量存储空间和处理能力的复杂的数字电路。时延路径中的交织处理器会消耗大量的存储空间以提供纠错能力。例如,一个典型的DSL收发器至少包括一个分配给其交织处理器大约16KB存储空间的时延路径。类似地,编码模块,例如,一个Reed Solomon编码器,消耗大量的处理能力。通常,随着时延路径数量的增加,通信系统中存储空间和处理能力的需求则会随之增长。
因此,本发明一方面在于使收发器中的一个或多个交织处理器和/或解交织处理器共享存储空间。特别地,本申请的一方面在于提供收发器中可共享的时延路径存储器。
本发明的另一方面在于配置和初始化通信系统中的可共享存储器。特别地,本发明的一方面涉及配置和初始化通信系统中的交织处理器/解交织处理器存储空间。
本发明的另一方面在于确定可由通信系统分配给特定组件的存储空间大小。特别地,本发明涉及确定可由通信系统分配给一个或多个交织处理器或解交织处理器的最大存储空间。
本发明的另一方面在于,处理能力被多个收发器模块共享。特别地,根据本发明的实施例,一个编码模块被一个或多个编码器和/或解码器共享。
本发明的另一个典型实施例涉及在一次或多次初始化和SHOWTIM(用户数据传输)期间,从一个固定容量存储结构转换成一个共享存储结构。
本发明的另一方面在于基于通信条件的改变动态更新一个或多个共享的存储空间及处理资源。
本发明的另一方面在于基于一个更新的通信参数更新一个或多个共享的存储空间及处理资源。
本发明的另一方面在于基于一个(或一些)更新的通信参数更新一个或多个共享存储空间及处理资源的分配。
本发明的另一方面在于交换收发器之间的共享资源分配。
本发明还提供一种为收发器分配共享存储空间的方法,其中包括将共享存储器分配给多个模块,所述多个模块中的每一个均包括至少一个交织处理器,至少一个解交织处理器或两者的结合。
上述方法进一步包括其中所述多个模块包括多个交织处理器。
上述方法进一步包括其中所述多个模块包括多个解交织处理器。
上述方法进一步包括其中所述多个模块的包括至少一个交织处理器和至少一个解交织处理器。
本发明的实施方式还涉及一种收发器,其中包括多个模块,所述多个模块中的每一个均包括至少一个交织处理器,至少一个解交织处理器或两者的结合,并将一个共享存储器分配给所述多个模块。
上述收发器进一步包括其中所述多个模块包括多个交织处理器。
上述收发器进一步包括其中所述多个模块包括多个解交织处理器。
上述收发器进一步包括其中所述多个模块的包括至少一个交织处理器和至少一个解交织处理器。
本发明的上述及其它的特征和优点将在之后的具体实施方式中进行详细描述。

图1为根据本发明的典型的收发器的功能性框图;
图2为根据本发明的典型的共享资源的方法的流程图;
图3为根据本发明的典型的确定共享存储空间最大值的方法的流程图;

具体实施方式
本发明的具体实施方式描述为关于有线和/或无线通信环境中的资源共享。但是,应当理解,通常,本发明所涉及的系统和方法可以等效的应用于任何环境的任何类型通信系统。
本发明的典型的系统和方法还描述为关于多载波调制解调器,例如DSL调制解调器和VDSL调制解调器,以及相关的通信硬件,软件和通信信道。但是,为了避免对本发明不必要的描述,以下描述中忽略了在框图或其它概述中的关于公知的结构和装置的说明。
出于说明的目的,此处提供许多细节以帮助全面了解本发明。但是,应当意识到,本发明还可以在超出此处说明细节之外的各种方式中实践。
此外,尽管当前实施方式指示系统中配置了各种组件,但是应当了解,该各种组件也可配置在分布式网络中的远端部分,例如电话电信网络和/或因特网,或者在专用安全,非安全和/或加密系统中。因此,应当意识到,系统中的组件可以包括在一个或多个装置(例如调制解调器)中,或者配置在一个分布式网络(例如电话电信网络)中的特定节点上。正如以下将说明的,为了计算的效率,系统的组件可以被设置在分布式网络的任何不会影响系统的操作的位置。例如,各种组件可以被设置在一个中心局调制解调器(CO,ATU-C,VTU-O)一个客户端调制解调器(CPE,ATU-R,VTU-R),一个DSL管理装置,或者其结合。类似的,系统中的一个或多个功能模块也可以分布在调制解调器和相关的计算装置之间。
此外,应当意识到,各种链路,包括通信信道5,可以有线或无线的链接各单元,或其结合,或者任何其它已知或之后开发的可以与相连接的元件供应和/或传送数据的元件。模块这一术语涉及任何已知或之后开发的可执行与该元件相关的功能的硬件,软件,固件,或其结合。确定、计算和用计算机计算这些术语,及其变化的形态,在此处是可互换的,并且包括任何类型的方法、过程、数学运算或技术。FCL模块和时延路径在此处可以互换,就像传输调制解调器和传输收发器。接收调制解调器和接收收发器同样可以互换。
图1示出一个应用共享资源的收发器100。应当意识到为了清楚的说明,该收发器的多个功能组件被忽略了。但是,收发器100还可以包括当前发明主题所属技术领域中典型的通信装置中的组件。
根据本发明的具体实施方式,存储空间和处理能力可以被多个发送器和/或接收器时延路径共享,通信收发器可以执行或支持多应用。例如,该收发器的发送器和/或接收器时延路径可以共享一个交织处理器/解交织处理器的存储空间,并且该共享的存储空间可以被分配给每个时延路径的交织处理器和/或解交织处理器。该分配可基于数字率,时延,BER,该应用的脉冲噪声保护需求,通过每个时延路径传送的数据或信息,或者通信系统中的任何相关参数。
同样的,例如,发送器和/或接收器时延路径可以共享一个Reed-Solomon编码器/解码器处理模块,并且该模块的处理资源可被分配给每个编码器和/或解码器。该分配可基于数字率/时延,BER,该应用的脉冲噪声保护需求,通过每个时延路径传送的数据或信息,或者通信系统中的任何相关参数。
根据一个典型的操作实施方式,第一收发器和第二收发器,例如在初始化期间,相互传输包括每个收发器的总存储容量和/或共享存储容量信息和关于一个或多个时延路径的任选信息的消息。这一信息可以预先被传输以确定如何配置时延路径以支持其应用需求。基于这一信息,调制解调器中的一个可以选择一个适合于每个时延路径所传送的每个应用的传送需求的FCI配置参数。尽管其后本发明的典型的实施例中描述的是在初始化期间的运行及特征,但应当意识到该资源的共享是可以调整的,并且两收发器之间消息的传送可以在任何时间进行,无论是初始化期间和/或用户数据传输期间,即SHOWTIME。
图1表示收发器100的一个典型的实施例。收发器100包括一个发送器部分200和一个接收器部分300。该发送器部分200包括一个或多个时延路径210,220,......类似的,接收器部分300包括一个或多个时延路径310,320,......每个发送器部分200的时延路径都包括一个成帧器,编码器,和交织处理器,分别标记为212,214,216和222,224和226。每个接收器部分300的时延路径都包括一个解帧器,解码器,和解交织处理器,分别标记为312,314,316和322,324和326。收发器100进一步包括一个共享处理模块110,一个共享存储器120,一个参数确定模块130,一个路径模块140,一个分配模块150,和一个共享资源管理模块160,上述模块通过一个或多个链接被内部连接(未示出)。
在这一实施例中,收发器100示例为包括发送器部分和接收器部分共四个时延路径,即210,220,310和320。共享存储器120由两个发送器部分的交织处理器216和226和两个接收器部分的解交织处理器316和326共享。共享处理模块110,如共享编码模块,由两个发送器部分的编码器214和224和两个接收器部分的解码器314和324共享。
尽管本发明的典型的实施例中描述的是收发器具有多个发送器部分时延路径和接收器部分时延路径,但应当意识到本发明可以应用于具有任何数量时延路径的任何收发器。此外,还应当意识到共享资源的分配可以是一个或多个发送器部分时延路径分享一个共享资源,一个或多个接收器部分时延路径分享一个共享资源,或者是一部份的发送器部分时延路径和一部份的接收器部分时延路径分享一个共享资源。此外,任何一个或多个时延路径,或者其中一部份,也可能被分配有一个固定容量的存储空间,例如时延路径的其他部分分享一个共享资源的时候。例如,在时延路径210中,交织处理器216被分配一部份共享存储器120,编码器214被分配给一个专用处理模块,反之亦然。
根据本实施例,多个发送器部分或接收器部分时延路径共享一个交织处理器/解交织处理器存储空间,如共享存储器120,和一个编码模块,如共享处理模块110。例如,交织处理器/解交织处理器存储空间可以被分配给不同的交织处理器和/或解交织处理器。该分配可以基于该被传送的应用的通信系统参数,例如数据率,延时,BER,脉冲噪声保护,以及类似内容。类似的,可以作为共享处理模块110的一部份的编码模块,可以被任何一个或多个时延路径共享。这一共享可以基于该被传送的应用的需求参数,例如数据率,延时,BER,脉冲噪声保护,以及类似内容。
例如,一个典型的收发器可能包括一个共享交织处理器/解交织处理器存储空间和可能被设置为分配该共享存储器120的第一部分给一交织处理器,如收发器的发送器部分的交织处理器216,并分配该共享存储器120的第二部分给一解交织处理器,如收发器的接收器部分的解交织处理器316。
作为替代方案,例如,一个典型的收发器可以包括一个共享交织处理器/解交织处理器存储空间,如共享存储器120,并被设置为分配该共享存储器120的第一部分给第一交织处理器,如收发器的发送器部分的交织处理器216,并分配该共享存储器的第二部分给第二交织处理器,如收发器的发送器部分的交织处理器226。
作为替代方案,例如,一个典型的收发器可以包括一个共享交织处理器/解交织处理器存储空间并被设置为分配该共享存储器120的第一部分给第一解交织处理器,如收发器的接收器部分的解交织处理器316,并分配该共享存储器的第二部分给第二解交织处理器,如收发器的接收器部分的解交织处理器326。不考虑其结构,通常任何交织处理器或解交织处理器,或其组合,无论其在收发器的发送器部分或接收器部分均可以与共享存储器120的一部份相关联。
共享资源的建立、配置及使用在以下实施方式中实现。首先,在与路径模块140的协作下,确定发送器和接收器时延路径数量(N)。然后参数确定模块130分析一个或多个参数,如数据率,发送数据率,接收数据率,脉冲噪声保护,位误码率,延时,诸如此类。基于一个或多个该参数,分配模块150分配共享存储器120的一部份给一个或多个交织处理器和/或解交织处理器,或其组合。这一处理持续至该存储器分配被确定并设置给了该N个时延路径中的每一个。
在共享资源管理160的协作下,确定了每个时延路径的存储空间的分配,收发器100发送给第二收发器以下内容中的一个或多个:时延路径的数量(N)、任意一个或多个时延路径的最大交织处理器存储空间和/或所有时延路径的总存储空间和/或共享存储空间的最大值。
以下描述了三个关于收发器中的交织处理器/解交织处理器共享存储空间和编码处理的实施例。这些实施例中的时延路径可以处于收发器的发送器部分或接收器部分。
实施例#1
第一发送器部分或接收器部分时延路径可以传送来自一视频应用的数据,该视频应用需要很低的BER但是可以允许较高的延时。既然如此,这一视频将通过一具有大量的交织/解交织和编码(也被认为是向前纠错FEC编码)的时延路径传送。例如,时延路径可以被配置为使用长度为255字节(N=255)、带有16位检验字(R=16)的Reed-Solomon编码和使用交织深度为64(D=64)的交织处理器的交织/解交织。这一时延路径需要N*D=16*255=16KB的发送器中的交织处理器存储空间(或者接收器中的解交织处理器存储空间)。这一时延路径将能够纠正工作期间内小于512字节的突发错误。
第二发送器部分或接收器部分时延路径可以传送因特网访问应用,该因特网访问应用需要中级的BER和中量的延时。既然如此,这一因特网访问应用将通过一具有中量的交织和编码的时延路径传送。例如,时延路径可以被配置为使用长度为128字节(N=128)、带有8位检验字(R=8)的Reed-Solomon编码和使用交织深度为16(D=32)的交织处理器的交织/解交织。这一时延路径需要N*D=128*32=4KB的发送器中的交织处理器存储空间和相同数量的解交织处理器存储空间。这一时延路径将能够纠正工作期间内小于128字节的突发错误。
第三发送器部分或接收器部分时延路径可以传送来自一语音电话应用,该语音电话应用需要很低的延时但是可以允许较高的BER。既然如此,这一语音将通过一具有少量的交织和编码的时延路径传送。例如,第三发送器部分或接收器部分时延路径可以被配置为没有交织或编码从而通过时延路径时尽可能低的延时,但是将无法提供纠错功能。
根据本发明的原理,支持上述实施例#1中所述的三种应用的系统,应当具有共享一个存储空间至少有16+4=20KB的三个时延路径。这三个时延路径还共享一个可以同时以两个N=255/R=16和N=128/R=8的编码字编码(在发送器部分)或解码(在接收器部分)的共享编码模块。
根据本发明的一个实施例,该时延路径可以在初始化或者数据传输模式期间(也被称为ADSL和VDSL收发器的SHOWTIME)被重新配置。这将会发生在,例如,应用或多个应用的需求被改变时。
实施例#2
如果由3个因特网访问应用代替1个视频应用、1个因特网应用和1个语音应用,则发送器部分和/或接收器部分时延路径将被重新配置以不同方式利用共享存储器和编码模块。例如,系统可以被重新配置为具有3个发送器部分或接收器部分时延路径,每个时延路径都被配置为使用长度为128字节(N=128)、带有8位检验字(R=8)的Reed-Solomon编码和使用交织深度为16(D=32)的交织处理器的交织。每个时延路径将需要N*D=128*32=4KB的交织处理器存储空间并且每个模块都能够纠正工作期间内小于128字节的突发错误。基于上述执行三个因特网访问应用的实施例,这三个时延路径共享一个至少有3*4=12KB的存储空间。这三个时延路径也共享一个可以同时以三个N=128/R=8,N=128/R=8和N=128/R=8的编码字编码(在发送器部分)或解码(在接收器部分)的共享编码模块。
实施例#3
系统可以被配置为执行其它组的请求。例如,时延信道可以被配置为传送2个视频应用。既然如此,只需要2个发送器部分或接收器部分时延路径,这意味着第三时延路径可以被简单地禁用。并且,假定存储空间限于上述实施例1,则这两个时延路径的最大共享存储空间为20KB。既然如此,系统可以被重新配置为两个时延路径,每个模块都被配置为使用长度为200字节(N=200)、带有10位检验字(R=10)的Reed-Solomon编码和使用交织深度为50(D=50)的交织处理器的交织/解交织。每个时延路径将需要N*D=200*50=10KB的交织处理器存储空间并且每个模块都能够纠正工作期间内小于250字节的突发错误。这一配置可以为两个时延路径提供20K的共享存储空间,与第一实施例相同。为了保持时延路径的存储空间限制,每个时延路径的纠错性能被从实施例#1中的512字节降低到250字节。
本申请的另一个方面在于如何在第一调制解调器和第二调制解调器之间传送FCI配置信息。FCI配置信息将依靠于DSL链接上所传输的应用的需求。这一信息可能需要在初始化期间被传送以用于初始配置该DSL链接。这一信息还可能需要在SHOWTIME期间被传送以用于基于应用或这些应用的需求的改变重新配置DSL链接。
根据一个实施例,第一调制解调器确定特定的FCI配置参数,例如上述定义的N,D,R,以适应特定的应用需求,例如延时,突发错误的纠错能力,等。为了确定该FCI配置参数,第一调制解调器必须知道第二调制解调器的性能。例如,第一调制解调器必须知道第二调制解调器可以支持多少个时延路径(FCI模块)。并且第一调制解调器必须知道每个发送器时延路径的交织处理器存储空间的最大值。此外,因为发送器时延路径可能共享一个公用存储空间,所以第一调制解调器必须知道所有的发送器时延路径共享的所有存储器空间。这样第一调制解调器可以选择一个适合应用需求和第二调制解调器的发送器部分时延路径性能的参数。
例如,使用上述实施例中的值,在初始化期间或SHOWTIME期间,第一收发器可发送一消息给第二收发器,包括如下信息:
●支持的发送器和接收器时延路径数=3
●时延路径#1的最大交织处理器存储空间=16KB
●时延路径#2的最大交织处理器存储空间=16KB
●时延路径#3的最大交织处理器存储空间=16KB
●所有时延路径的最大全体/共享存储空间=20KB
基于这一信息,以及应用需求,第一收发器将选择时延路径设置值。例如,如果应用为1个视频,1个因特网访问和1个语音应用,第一收发器可按如下方式配置3个时延路径:
时延路径#1-视频:N=255,R=16,D=64
时延路径#2-因特网:N=128,R=8,D=32
时延路径#3-语音:N=0,R=0,D=1(无编码或交织)
这会造成总共20KB的交织处理器存储空间。
可选择的,例如,只有两个视频应用,则第一收发器可基于如下方式配置2个时延路径:
时延路径#1-视频:N=200,R=10,D=50
时延路径#2-视频:N=200,R=10,D=50
时延路径#3-视频:N=0,R=0,D=1(无编码或交织)
这也会造成总共20KB字节的交织处理器存储空间。
可选择的,第二收发器可以确定特定的FCI配置参数,例如上述定义的N,D,R,以适应特定的应用需求,例如延时,突发错误的纠错能力,等。如关于第一收发器中所述,为了确定FCI配置参数,第二收发器必须知道第一收发器的性能。既然如此,第一收发器应当发送给第二收发器包含上述内容的消息,并且第二收发器基于该消息和应用需求选择时延路径性能参数。
图2概述了关于收发器中分配共享存储空间的方法的实施方式。特别是,控制由步骤S200开始并继续到步骤S210。在步骤S210,一个或多个共享交织处理器/解交织处理器存储空间和/或共享编码器/解码器处理资源被分配给收发器中的一个或多个时延路径。控制继续到步骤S220并终止。
图3概述了本发明中关于交换共享资源分配的方法的实施方式。特别是,控制由步骤S310开始。在步骤S310,确定可分配给收发器中多个交织处理器或解交织处理器中特定交织处理器或解交织处理器的最大存储空间。接下来,在步骤S320,所确定的分配给一个或多个解交织处理器和/或交织处理器的最大值被传送给另一个收发器。包括额外的信息的消息也可以传送给另一个收发器或者从另一个收发器接收。控制继续到步骤S330并终止。
图4概述了本发明中关于资源共享过程的实施方式。特别是,控制由步骤S400开始并继续到步骤S410。在步骤S410,确定时延路径的数量。然后,在步骤S420,时延路径信息(FCI模块信息)被传送给另一个收发器。包括额外的信息的消息也可以传送给另一个收发器或者从另一个收发器接收。该信息可以用于,例如,帮助确定收发器中的存储空间分配。此外,从其它收发器接收的消息可以指明存储空间分配所基于的内容,例如,时延路径的数量,远端收发器的存储器分配和应用需求。控制继续到步骤S430。
在步骤S430,每个时延路径执行步骤440中的步骤。
步骤440中,在监视资源分配的执行期间,执行步骤450和460。特别是,在步骤S450,一个或多个与通信系统相关的参数被确定。然后,在步骤S460,基于一个或多个通信参数,共享资源被分配。控制继续到步骤S470。
在步骤S470,共享资源的分配被通知给另一个收发器。接下来,在步骤S480,确定通信系统中是否存在一个需要调整共享资源的分配的改变。该通信条件的改变包括通过系统传输的应用的改变和/或信道条件的改变,等。如果需要调整,控制跳转回步骤S410。否则,控制跳到步骤S490并终止。
