71 / 452 page  S12CPUV2 Reference Manual, Rev. 4.0 Freescale Semiconductor 71 5.17 Multiply and Accumulate Instruction The multiply and accumulate (EMACS) instruction multiplies two 16-bit operands stored in memory and accumulates the 32-bit result in a third memory location. EMACS can be used to implement simple digital filters and defuzzification routines that use 16-bit operands. The WAV instruction incorporates an 8- to 16-bit multiply and accumulate operation that obtains a numerator for the weighted average calculation. The EMACS instruction can automate this portion of the averaging operation when 16-bit operands are used. Table 5-15 shows the EMACS instruction. Table 5-15. Multiply and Accumulate Instructions Mnemonic Function Operation EMACS Multiply and accumulate (signed) 16 bit by 16 bit ⇒ 32 bit ((M(X):M(X+1)) × (M(Y):M(Y+1))) + (M ~ M + 3) ⇒ M ~ M + 3 |
