2.7 Table 2.10 lists 6812′s special instructions, which are arithmetic instructions of primary interest in fuzzy logic. They use index addressing, which is discussed in the next topic. Fuzzy logic uses minimum and maximum functions to logically AND and OR fuzzy variables. The 6812 has instructions max a, maxm, mina, minm, emaxd, emaxm. emind, and […]
2.8 One might wonder why some move instructions, such as LDAA, TSTA, and STAA, always put V = 0 rather than leaving V unchanged as they do C. The reason is that doing so allows all of the signed branches to work after these instructions as well as after the arithmetic type of instruction. For […]
