COMPUTER ORGANIZATION & ARCHITECTUREThe x86 architecture includes an instruction called decimal adjust after addition (DAA). DAA performs the following sequence of instructions: ``plaintext if((AL AND 0FH) > 9) OR (AF = 1) then AL ← AL + 6; AF ← 1; else AF ← 0; endif; if(AL > 9FH) OR (CF = 1) then AL ← AL + 60H; CF ← 1; else CF ← 0; endif. `` "H" indicates hexadecimal. AL is an 8-bit register that holds the result of addition of two unsigned 8-bit integers. AF is a flag set if there is a carry from bit 3 to bit 4 in the result of an addition. CF is a flag set if there is a carry from bit 7 to bit 8. Explain the function performed by the DAA instruction.202214mOPERATING SYSTEMIf the size of logical address space is 2^m, and a page size is 2^n addressing units, then the high order bits of a logical address designate the page number, and the low order bits designate the page offset.
