DSP课程设计-正弦信号发生器的设计

会运用汇编语言进行程序设计x3x5x7x9x3x5x7x923456789本实验是基于CCS开发环境的。CCS是TI公司推出的为开发TMS320系列DSP软件的集成开发环境，是目前使用最为广泛的DSP开发软件之一。它提供X角度值相对应，可以利用DSP处理器处理大量重复计算的优势来计算x轴每一sSaveQuitSetupCCStudiov并启动运行CCStudio。在CCS环境下，点击file/new/sourcefile菜单命令，打开一个空白文档，将汇编类型为*.asm。t在工程中添加源文件，执行菜单project/addfilestoproject，把sin文件添加到工 (1)选择菜单命令Project→RebuildAll，对工程重新编译、汇编和链接，主窗口(2)选择菜单命令File→LoadProgram，在当前目录的Debug目录下选择sin并BuildDSP。 (3)选择菜单命令Debug→Run或在Debug工具栏上单击Run按钮，运行该程gragh汇编源程序sinmmregs.defstart.defd_xs,d_sinx,d_xc,d_cosx,sinx,cosxx.usect"sin_x",360STACK:.usect"STACK",10Hk_theta.set286;theta=pi/360(0.5deg)STM#STACK+10H,SPSTMk_theta,AR0STM0,AR1STM#sin_x,AR6STM#90,BRCRPTBloop1-1LDMAR1,ALD#d_xs,DPSTLA,@d_xsSTLA,@d_xcCALLsinx;d_sinx=sin(x)CALLcosx;d_cosx=cos(x)LD#d_sinx,DPLD@d_sinx,16,A;A=sin(x)MPYA@d_cosx;B=sin(x)*cos(x)STHB,1,*AR6+;AR62*sin(x)MAR*AR1+0loop1:STM#sin_x+89,AR7;sin91(deg.)-sin179(deg.)STM#88,BRCRPTBloop2-1LD*AR7-,ASTLA,*AR6+loop2:STM#179,BRC;sin180(deg.)-sin359(deg.)STM#sin_x,AR7RPTBloop3-1LD*AR7+,ANEGASTLA,*AR6+loop3:STM#sin_x,AR6;generatesinwaveSTM#1,AR0STM#360,BKBloop3.defd_xs,d_sinxtable_s.word01C7H;C1=1/(8*9).word030BH;C2=1/(6*7).word0666H;C3=1/(4*5).word1556H;C4=1/(2*3)d_d_coef_sd_xsd_squr_xsd_temp_sd_sinxd_l_sectct.usectusect.usect.usectSSBX"coef_s",4"sin_vars",1"sin_vars",1"sin_vars",1"sin_vars",1"sin_vars",1FRCTSTM#d_coef_s,AR5;movecoeffstable_sRPT#3MVPD#table_s,*AR5+STM#d_coef_s,AR3STM#d_xs,AR2STM#d_l_s,AR4ST#7FFFH,d_l_sSQUR*AR2+,A;A=x^2STA,*AR2;(AR2)=x^2MASR*AR2+,*AR3+,B,A;A=1-x^2/72,T=x^2MPYAA;A=T*A=x^2(1-x^2/72)STHA,*AR2;(d_temp)=x^2(1-x^2/72)MASR*AR2-,*AR3+,B,A;A=1-x^2/42(1-x^2/72);T=x^2(1-x^2/72)MPYA*AR2+;B=x^2(1-x^2/42(1-x^2/72))STB,*AR2;(d_temp)=x^2(1-x^2/42(1-x^2/72))MASR*AR2-,*AR3+,B,A;A=1-x^2/20(1-x^2/42(1-x^2/72))MPYA*AR2+;B=x^2(1-x^2/20(1-x^2/42(1-x^2/72)))STB,*AR2;(d_temp)=BMASR*AR2-,*AR3+,B,A;A=1-x^2/6(1-x^2/20(1-x^2/42(1-x^2/72)))MPYAd_xs;B=x(1-x^2/6(1-x^2/20(1-x^2/42(1-x^2/72))))STHB,d_sinx;sin(theta)RETosxd_coef_ctable_osxd_coef_ctable_c.usect"coef_c",4.word0249H;C1=1/(7*8).word0444H;C2=1/(5*6).word0AABH;C3=1/(3*4).word4000H;C4=1/2xcd_squr_xcdxcd_squr_xcd_temp_c.usect"cos_vars",1.usect"cos_vars",1d_cosxc_l_c.usect"cos_vars",1.usect"cos_vars",1SSBXFRCTSTM#d_coef_c,AR5;movecoeffstable_cRPT#3MVPD#table_c,*AR5+STM#d_coef_c,AR3STM#d_xc,AR2STM#c_l_c,AR4ST#7FFFH,c_l_cSQUR*AR2+,A;A=x^2STA,*AR2;(AR2)=x^2MASR*AR2+,*AR3+,B,A;A=1-x^2/56,T=x^2MPYAA;A=T*A=x^2(1-x^2/56)STHA,*AR2;(d_temp)=x^2(1-x^2/56)MASR*AR2-,*AR3+,B,A;A=1-x^2/30(1-x^2/56);T=x^2(1-x^2/56)MPYA*AR2+;B=x^2(1-x^2/30(1-x^2/56))STB,*AR2;(d_temp)=x^2(1-x^2/30(1-x^2/56))MASR*AR2-,*AR3+,B,A;A=1-x^2/12(1-x^2/30(1-x^2/56))SFTAA,-1,A;-1/2NEGAMPYA*AR2+;B=-x^2/2(1-x^2/12(1-x^2/30(1-x^2/56)))MAR*AR2+RETDADD*AR4,16,B;B=-x^2/2(1-x^2/12(1-x^2/30(1-x^2/56)))STHB,*AR2;cos(theta)RET.end.mmregs.defstart.defd_xs,d_sinx,d_xc,d_cosx,sinx,cosxxect"sin_x",360STACK:usect"STACK",10Hk_theta286;theta=pi/360(0.5deg)TMTMTMTMTMRPTB#STACK+10H,SPk_theta,AR00,AR1#sin_x,AR6#90,BRCloop1-1AR1,AAR1,A#d_xs,DPA,@d_xsA,@d_xc#d_sinx,DP@d_sinx,16,AB,1,*AR6+*AR1+0;d_sinx=sin(x);d_cosx=cos(x)Asin(x);B=sin(x)*cos(x);AR62*sin(x)LDTLTLCALLCALLLDLDMPYAHMARSTM#STM#sin_x+89,AR7;sin91(deg.)-sin179(deg.)STM#88,BRCRPTBloop2-1LD*AR7-,ASTLA,*AR6+STM#179,BRC;sin180(deg.)-sin359(deg.)STM#sin_x,AR7RPTBloop3-1LD*AR7+,Aloop2:NEGASTLA,*AR6+loop3:STM#sin_x,AR6;generatesinloop3:STM#1,AR0STM#360,BKBloop3.defd_xs,d_sinxtable_s.word01C7H;table_s.word030BH;C2=1/(6*7).word0666H;C3=1/(4*5).word1556H;C4=1/(2*3)d_coef_sd_xsd_coef_sd_xsd_squr_xsd_temp_sd_sinxd_l_s.usect"sin_vars",1.usect"sin_vars",1.usect"sin_vars",1.usect"sin_vars",1.usect"sin_vars",1SSBXFRCTSTM#d_coef_s,AR5;movecoeffstable_sRPT#3MVPD#table_s,*AR5+osxd_coef_ctable_cxcd_squr_xcd_temp_cd_cosxc_l_cSTM#d_coef_s,AR3STM#d_xs,AR2STM#d_l_s,AR4ST#7FFFH,d_l_sSQUR*AR2+,A;A=x^2STA,*AR2;(AR2)=x^2MASR*AR2+,*AR3+,B,A;A=1-x^2/72,T=x^2MPYAA;A=T*A=x^2(1-x^2/72)STHA,*AR2;(d_temp)=x^2(1-x^2/72)MASR*AR2-,*AR3+,B,A;A=1-x^2/42(1-x^2/72);T=x^2(1-x^2/72)MPYA*AR2+;B=x^2(1-x^2/42(1-x^2/72))STB,*AR2;(d_temp)=x^2(1-x^2/42(1-x^2/72))MASR*AR2-,*AR3+,B,A;A=1-x^2/20(1-x^2/42(1-x^2/72))MPYA*AR2+;B=x^2(1-x^2/20(1-x^2/42(1-x^2/72)))STB,*AR2;(d_temp)=BMASR*AR2-,*AR3+,B,A;A=1-x^2/6(1-x^2/20(1-x^2/42(1-x^2/72)))MPYAd_xs;B=x(1-x^2/6(1-x^2/20(1-x^2/42(1-x^2/72))))STHB,d_sinx;sin(theta)RET.defd_xc,d_cosx.usect"coef_c",4.word0249H;C1=1/(7*8).word0444H;C2=1/(5*6).word0AABH;C3=1/(3*4).word4000H;C4=1/2.usect"cos_vars",1.usect"cos_vars",1.usect"cos_vars",1.usect"cos_vars",1.usect"cos_vars",1SSBXFRCTSTM#d_coef_c,AR5;movecoeffstable_cRPT#3MVPD#table_c,*AR5+STM#d_coef_c,AR3STM#d_xc,AR2STM#c_l_c,AR4ST#7FFFH,c_l_cSQURMASRMPYASTHMASRMPYAMASRSFTANEGMPYAMARRETDADDSTHRET*AR2+,AA,*AR2*AR4,B*AR2+,*AR3+,B,AAA,*AR2*AR2-,*AR3+,B,A*AR2+B,*AR2*AR4,B*AR2-,*AR3+,B,AA,-1,AA*AR2+*AR2+*AR
