Device-dependent Information DSP96000 Information F-14 DSP ASSEMBLER REFERENCE MANUAL MOTOROLA F.3.3 Condition Code Mnemonics Following are the DSP96000 condition code mnemonics which correspond to the condi- tional instructions based on the CCR condition codes. These tests may be used in an op- erand comparison expression within a structured control statement (Chapter 7). <CC> — carry clear <CS> — carry set <EQ> — equal <FEQ> — float equal <FERR> — float error <FGE> — float greater or equal <FGL> — float greater or less than <FGLE> — float greater, less, or equal <FGT> — float greater than <FINF> — float infinity <FLE> — float less or equal <FLT> — float less than <FMI> — float minus <FNE> — float not equal <FNGE> — float not greater or equal <FNGL> — float not greater or less than <FNGLE> — float not greater, less, or equal <FNGT> — float not greater than <FNLT> — float not less than <FOR> — float ordered <FPL> — float plus <FUN> — float unordered <GE> — greater or equal <GT> — greater than <HI> — higher <HS> — higher or same <LE> — less or equal <LO> — lower <LS> — lower or same <LT> — less than <MI> — minus <NE> — not equal <PL> — plus <VC> — overflow clear <VS> — overflow set Device-dependent Information DSP56100 Information MOTOROLA DSP ASSEMBLER REFERENCE MANUAL F-15 F.4 DSP56100 INFORMATION The Motorola DSP56100 refers to a family of high-speed, low power programmable CMOS processors. The DSP56100 supports16-bit signed fixed-point fractional and signed and unsigned integer arithmetic. F.4.1 Instruction Set Summary DSP56100 instructions can be grouped by function into six types: 1. Arithmetic instructions 2. Logical instructions 3. Bit manipulation instructions 4. Loop instructions 5. Move instructions 6. Program control instructions F.4.1.1 Arithmetic Instructions The DSP56100 instructions used for arithmetic operations are: ABS — Absolute value* ADC — Add long with carry ADD — Add* ASL — Arithmetic shift accumulator left* ASL4 — 4-bit arithmetic shift accumulator left ASR — Arithmetic shift accumulator right* ASR4 — 4-bit arithmetic shift accumulator right ASR16 — 16-bit arithmetic shift accumulator right CLR — Clear accumulator* CLR24 — Clear 24 MS bits of accumulator* CMP — Compare* CMPM — Compare magnitude* DEC — Decrement accumulator* DEC24 — Decrement 24 MS bits of accumulator* DIV — Divide iteration DMAC — Multiply-accumulate with 16-bit right shift EXT — Sign extend accumulator IMAC — Integer multiply-accumulate IMPY — Integer multiply INC — Increment accumulator* *Instruction allows parallel data move.
