DSP编程指令全集
ABS	Absolute Value of Accumulator If the contents of the accumulator are less than zero, replace the contents with the 2s complement of the contents. If the contents are .0, the accumulator is not affected.
ADCB	Add ACCB to Accumulator With Carry Add the contents of the ACCB and the value of the carry bit to the accumulator. If the result of the addition generates a carry from the accumulator’s MSB, the carry bit is set to 1.
ADD dma [ ,shift] ADD { ind} [ ,shift [ ,next ARP] ] ADD # k ADD # lk [ ,shift2]	Add to Accumulator With Shift TMS320C1x and TMS320C2x devices: add the contents of the addressed data memory location to the accumulator; if a shift is specified, left-shift the contents of the location before the add. During shifting, loworder bits are zero-filled, and high-order bits are sign-extended. TMS320C2xx and TMS320C5x devices: add the contents of the addressed data memory location or an immediate value to the accumulator; if a shift is specified, 非接触测量left-shift the data before the add. During shifting, loworder bits are zero-filled, and high-order bits are sign-extended if SXM = 1.
ADDB	Add ACCB to Accumulator Add the contents of the ACCB to the accumulator.
ADDC dma ADDC { ind} [ ,next ARP]	Add to Accumulator With Carry Add the contents of the addressed data memory locationand the carry bit to the accumulator.
ADDH dma ADDH { ind} [ ,next ARP]	Add High to Accumulator Add the contents of the addressed data memory location to the 16 MSBs of the accumulator. The LSBs are not affected. If the result of the addition generates a carry, the carry bit is set to 1. TMS320C2x, TMS320C2xx, and TMS320C5x devices: If the result of the addition generates a carry from the accumulator’s MSB, the carry bit is set to 1.
ADDK # k	Add to Accumulator Short Immediate TMS320C1x devices: Add an 8-bit immediate value to the accumulator. TMS320C2x, TMS320C2xx, and TMS320C5x devices: Add an 8-bit immediate value, right-justified, to the accumulator with the result replacing the accumulator contents. The immediate value is treated as an 8-bit positive number; sign extension is suppressed.
ADDS dma ADDS { ind} [ ,next ARP]	Add to Accumulator With Sign Extension Suppressed Add the contents of the addressed data memory location to the accumulator. The value is treated as a 16-bit unsigned number; sign extension is suppressed.
ADDT dma ADDT { ind} [ ,next ARP]	Add to Accumulator With Shift Specified by T Register 变频器开关电源 Left-shift the contents of the addressed data memory location by the value in the 4 LSBs of the T register; add the result to the accumulator. If a shift is specified, leftshift the data before the add. During shifting, low-order bits are zero-filled, and high-order bits are sign-extended if SXM = 1. TMS320C2xx and TMS320C5x devices: If the result of the addition generates a carry from the accumulator’s MSB, the carry bit is set to 1.
ADLK # lk [ ,shift]	Add to Accumulator Long Immediate With Shift Add a 16-bit immediate value to the accumulator; if a shift is specified, left-shift the value before the add. During shifting, low-order bits are zero-filled, and highorder bits are sign-extended if SXM = 1.
ADRK # k	Add to Auxiliary Register Short Immediate Add an 8-bit immediate value to the current auxiliary register.
AND dma AND { ind} [ ,next ARP] AND # lk [ ,shift]血氧仪测试方法	AND With Accumulator TMS320C1x and TMS320C2x devices: AND the contents of the addressed data memory location with the 16 LSBs of the accumulator. The 16 MSBs of the accumulator are ANDed with 0s. TMS320C2xx and TMS320C5x devices: AND the contents of the addressed data memory location or a 16-bit immediate value with the contents of the accumulator. The 16 MSBs of the accumulator are ANDed with 0s. If a shift is specified, left-shift the constant before the AND. Low-order bits below and high-order bits above the shifted value are treated as 0s.
ANDB	AND ACCB to Accumulator AND the contents of the ACCB to the accumulator.
ANDK # lk [ ,shift]	AND Immediate With Accumulator With Shift AND a 16-bit immediate value with the contents of the accumulator; if a shift is specified, left-shift the constant before the AND.ca3660
APAC	Add P Register to Accumulator Add the contents of the P register to the accumulator. TMS320C2x, TMS320C2xx, and TMS320C5x devices: before the add, left-shift the contents of the P register as defined by the PM status bits.
APL [ # lk] ,dma永磁悬浮 APL [ # lk,] { ind} [ ,next ARP]	AND Data Memory Value With DBMR or Long Constant AND the data memory value with the contents of the DBMR or a long constant. If a long constant is specified, it is ANDed with the contents of the data memory location. The result is written back into the data memory location previously holding the first operand. If the result is 0, the TC bit is set to 1; otherwise, the TC bit is cleared.
B pma B pma [ , { ind} [ ,next ARP] ]	Branch Unconditionally Branch to the specified program memory address. TMS320C2x and TMS320C2xx devices: modify the current AR and ARP as specified.
B[ D] pma [ , { ind} [ ,next ARP]	Branch Unconditionally With Optional Delayweb前端性能优化 Modify the current auxiliary register and ARP as specified and pass control to the designated program memory address. If you specify a delayed branch (BD), the next two instruction words (two 1-word instructions or one 2-word instruction) are fetched and executed before branching.
BACC	Branch to Address Specified by Accumulator Branch to the location specified by the 16 LSBs of the accumulator.
BACC[ D]	Branch to Address Specified by Accumulator With Optional Delay Branch to the location specified by the 16 LSBs of the accumulator. If you specify a delayed branch (BACCD), the next two instruction words (two 1-word instructions or one 2-word instruction) are fetched and executed before branching.
BANZ pma BANZ pma [ , { ind} [ ,next ARP] ]	Branch on Auxiliary Register Not Zero If the contents of the 9 LSBs of the current auxiliary register (TMS320C1x) or the contents of the entire current auxiliary register (TMS320C2x) are π0, branch to the specified program memory address. TMS320C2x and TMS320C2xx devices: modify the current AR and ARP (if specified) or decrement the current AR (default). TMS320C1x devices: decrement the current AR.
BANZ[ D] pma [ , { ind} [ ,next ARP] ]	Branch on Auxiliary Register Not Zero With Optional Delay If the contents of the current auxiliary register are π0, branch to the specified program memory address. Modify the current AR and ARP as specified, or decrement the current AR. If you specify a delayed branch (BANZD), the next two instruction words (two 1-word instructions or one 2-word instruction) are fetched and executed before branching.
BBNZ pma [ , { ind} [ ,next ARP] ]	Branch on Bit πZero If the TC bit = 1, branch to the specified program memory address. TMS320C2x devices: modify the current AR and ARP as specified. TMS320C2xx and TMS320C5x devices: if the –p porting switch is used, modify the current AR and ARP as specified.
