  關(guān)鍵詞: H.264/AVC 視頻編碼 整數(shù)變換 量化


  隨著數(shù)字化視頻技術(shù)在視頻電話,、視頻會議、DVD以及高清晰度數(shù)字電視等方面的應(yīng)用,,視頻壓縮標(biāo)準(zhǔn)也隨之不斷發(fā)展,。ITU-T制定的H.26x系列和ISO/IEC制定的MPEG-x系列,是視頻領(lǐng)域中兩大獨立的主流視頻壓縮標(biāo)準(zhǔn),。2003年,,這些組織又聯(lián)合推出新的視頻壓縮標(biāo)準(zhǔn)H.264/MPEG-4 -10AVC,簡稱H.264/AVC,。H.264/AVC采用一系列新的壓縮方法[1],,可獲得更好的壓縮效果,其壓縮率達(dá)到以往標(biāo)準(zhǔn)的1.5~2倍[2],。因此,,基于這一標(biāo)準(zhǔn)的相關(guān)研究和硬件實現(xiàn)具有重要的意義。視頻壓縮硬件實現(xiàn)的關(guān)鍵是編解碼模塊,,其中尤以編碼模塊最為核心,。本文主要研究編碼模塊中的4×4整數(shù)變換量化核,,提出硬件實現(xiàn)的優(yōu)化方法,,并采用Verilog HDL語言進(jìn)行硬件設(shè)計和綜合。
1 4×4整數(shù)變換量化核的原理
  在以前的視頻編碼標(biāo)準(zhǔn)如MPEG-2和H.263中,,對于預(yù)測的殘差數(shù)據(jù)都是采用8×8離散余弦變換(DCT)[1]作為變換的基本運算操作,;而在H.264/AVC編碼標(biāo)準(zhǔn)中,,則采用類似DCT變換形式的基于4×4 像素塊的整數(shù)變換。由于變換塊的尺寸縮小,,運動物體的劃分更精確,,而且運動物體邊緣處的銜接誤差大為減小。
  對于整數(shù)變換方式,,4×4像素塊的變換公式[3]為:
  
  式中,,(CXCT)是二維變換核,Ef是縮放因子矩陣,,符號表示CXCT矩陣?yán)锏拿總€元素和Ef矩陣中相同位置的元素相乘,,a=1/2,b=,。為了更有效地壓縮數(shù)據(jù),,需要利用量化的方法對變換后的數(shù)據(jù)進(jìn)行有損壓縮。同時,,由于整數(shù)變換需要利用矩陣行向量的歸一化因子進(jìn)行系數(shù)縮放處理,,為降低變換的運算量,在H.264/AVC標(biāo)準(zhǔn)中將變換的系數(shù)縮放并進(jìn)行量化運算處理,,避免了復(fù)雜的實數(shù)運算和除法運算,,更有利于硬件的實現(xiàn)。
  對于量化方式,,正向量化運算可由如下公式[3]實現(xiàn):
  
  式中,, Zij為量化后的系數(shù);Wij為變換矩陣W=CXCT中的元素;MF=·2q,,PF稱為縮放系數(shù),,根據(jù)元素在陣列塊中的不同位置,其取值如表1所示,,Qstep為量化步長,,由0至51共52個量化參數(shù)QP決定,QP增加1,, Qstep增加12.5%,; q=15+QP/6,QP/6取整數(shù),;對于幀內(nèi)宏塊f取2q/3,,幀間宏塊f取2q/6。需要指出的是,,MF的值可根據(jù)PF和QP的取值經(jīng)簡單計算得到,,并可形成表格,通過查表方式便可實現(xiàn)硬件運算,,并有效地提高了運算速度,。

2 4×4整數(shù)變換量化核的優(yōu)化設(shè)計
  為進(jìn)一步提高硬件運算速度,,減少硬件開銷,設(shè)計中采用了如下優(yōu)化方法:
  (1)在求取變換陣W=CXCT時,,根據(jù)變換的對稱性,,將X的列變換(矩陣左乘)與行變換(矩陣右乘)分開實現(xiàn),把二維變換分割為兩次一維變換,,并采用快速堞形算法[4]來實現(xiàn),。一維變換的快速算法實現(xiàn)如圖1所示,其中的列變換可用如下算式表示:
  
  對于每列變換,,需要進(jìn)行8次加法和2次移位運算,,而行變換則可根據(jù)矩陣轉(zhuǎn)置的性質(zhì)ABT=(BAT)T,將經(jīng)過列變換后的結(jié)果矩陣先進(jìn)行轉(zhuǎn)置,,再采用相同的變換形式運算,。這樣對4×4點數(shù)據(jù)做一次變換,只需通過8×8次加法和2×8次移位運算便可完成,。
  (2)針對不同運算的位寬需要,,設(shè)計專用的加法器和乘法器。本文對整數(shù)變換中的加法器采用三級流水線加法器,,實現(xiàn)9位加法,,每級流水線完成三位超前進(jìn)位加法,將邏輯延遲限制在三位加法器之內(nèi),。圖2給出了9位加法器的流水線實現(xiàn)框圖,。選用EPF10K10LC84-3作為適配器件,經(jīng)過Synplify Pro 7.3綜合,,結(jié)果表明這種加法器具有較優(yōu)的最高工作頻率和硬件開銷,。如表2所示, 常規(guī)加法器的最高工作頻率為37.0MHz,消耗資源卻為28LC,,而經(jīng)過優(yōu)化的三級流水線加法器在消耗資源增加不多的情況下,,其最高工作頻率相比常規(guī)加法器提高了257%,達(dá)到94.5MHz,。
  在量化過程中,,對于給定的量化參數(shù)QP, MF只有三種取值,,因此乘法實現(xiàn)可以采用無符號數(shù)乘法運算,,乘法結(jié)構(gòu)則采用16×14位加法樹乘法器。這樣,,在提高運算速度的同時節(jié)約了芯片面積,。
  (3)對于f的計算,在不影響運算精度的情況下本文采用近似處理。為了避免除法運算,,將f的計算式變形,,即:
  f=2q/3=(215/3)×2m≈[(215+1)/3]×2m≈10923×2m
  式中,, m取值為0~8,,具體由相應(yīng)的QP給出。由于f在完成加法運算后其結(jié)果還需左移q位,,所以計算精度不會受影響,。這樣,對f的計算只需進(jìn)行移位操作,。

3 4×4整數(shù)變換量化核硬件實現(xiàn)
  基于上述算法原理及其設(shè)計,,本文首先對4×4整數(shù)變換量化模塊進(jìn)行C語言編程,驗證了該模塊所采用算法的正確性,。然后采用Verilog HDL語言描述4×4整數(shù)變換和量化核(幀內(nèi)模式)的硬件功能,,并通過仿真軟件Modelsim SE 5.7進(jìn)行功能仿真,驗證了該模塊輸出結(jié)果與設(shè)計要求相一致,。最后采用Synplify Pro7.3綜合工具,,并以Altera公司的Stratix系列FPGA作為主要目標(biāo)適配器件進(jìn)行綜合。

  4×4整數(shù)變換量化核的二大子模塊的綜合結(jié)果如表3所示,,表中同時給出經(jīng)本文優(yōu)化設(shè)計前后的綜合結(jié)果作為對比,。可見,,經(jīng)本文采用的三種優(yōu)化設(shè)計處理后,,在硬件開銷改變不大情況下,變換子模塊的最高工作頻率達(dá)到59.4MHz,,是未優(yōu)化前的1.73倍,,而量化子模塊的最高工作頻率達(dá)到55.8MHz,是未優(yōu)化前的1.82倍,。4×4整數(shù)變換量化核的最高工作頻率取各子模塊的最低頻率,,這樣其優(yōu)化后的最高工作頻率是55.8MHz,相比優(yōu)化前的30.7MHz提高了82%,。


  本文對H.264/AVC協(xié)議中的4×4整數(shù)變換量化核從算法原理到硬件實現(xiàn)進(jìn)行了分析和設(shè)計,。采用自頂向下的Verilog HDL設(shè)計流程,實現(xiàn)了4×4整數(shù)變換量化核硬件功能的優(yōu)化設(shè)計,模塊的最高工作頻率提高了82%,,為H.264/AVC視頻編碼標(biāo)準(zhǔn)的硬件實現(xiàn)提供了參考,。
