1.DATA TRANSFER chemical group MOVE This group contains operating bidding manual that transfer information from memory to immortalize, prove to put down and register to memory. Data may be 8,16 or 32 bites in length. Adress and selective information registers may be use as strong as the system registers CCR (condition code register), USP (user fold pointer) and SR (status register). The data transfer instruction manual be: EXG re-sentencing registers LEA vitiate effective adress LINK link and portion MOVE start data MOVEA give-up the ghost adress MOVEM move three-fold registers MOVEP move peripheral data MOVEQ move quick pea plant push effective adress SWAP swap register halves UNLK unlink 2.ARTHIMETIC GROUP COUNTER The arithmetic group provides kick iniction and substraction, pf 8-,16- and 32- bit jimmy print and un write 16-bit by 16-bit multiplication: auguryed and un write 32-bit by 16-bit division; 8-,16-, and 32-bit drop offs, comp arings, tests; and negation. An additional operation called signaling extension is also available. These trading operations may be shaped on all adress and data registers and memory locations.

Arithmetic instructions are: ADD add binary ADDA add adress ADDI add immediate ADDQ add quick CLR clear operand CMP compare CMPA compare adress CMPI compare immediate CMPM compare memory DIVS divide signed poetry DIVU divide unsigned numbers EXT extend sign MULS multiply signed numbers etc. 3.LOGICAL GROUP AND, not The ratiocinative group is used to preform AND, OR, EOR, and NOT (ones complement) oper ations in 8-,16-, and 32-bit data contained ! in data registers, memory, and the CCR and SR systems. The logical instructions are: AND logical AND ANDI AND immediate OR dianoetic OR ORI OR immediate EOR max OR EORI Exclusive OR immediate NOT logical complement 4.SHIFT AND go around GROUP LAMP Shift and bear operations may preform on 8-,16-,and 32-bit data values contained in data registers or memory. The shift and rotate instructions are: ASL...If you want to take in a full essay, nightspot it on our website: OrderCustomPaper.com
