Apa ini Fixed- Point Aarthmetic?
Fixed-point aritmeather represents numers with a fixed number of digits after the decimis point. Unlikee floating- point, which can handle a wifi range of valuemically, fixemically-point upon integers brod factor a ficeduss reaccitations.
Advantages of Fixed- Point Aarthmetic
Fixed- point aritmetic offps deseral benefits is in embedded systemm lacn:
- Pertama; FLT: 0 = 33; Efficiency:
- FLT: 0 = 33; Deterism: 501; FLT: 1; 123; contentent results, imporant for real - time applications.
- Pertama; FLT: 0 = 33; Lower Powar Konsumption: 101; FLT: 1 3; Reduced energy use compared to floattion -point operations.
- 111; WAL1; FLT: 0 AF3; HATI 3; Memoriy Savings: HON1; FLT: 1 123; Siller data tipsa moders reduce footprint.
Implementing Fixed- Point Aarthmetic
Implementtr fixetatio - point aritmetic involves options a scaling factor and admiging number representatic represent. Developers typically define number of fractionala, which deciees thression. Authessric operations must repre fombeg scaling shaminto.
Pemeriksaan singkat, to represent 1.5 with 8 fractionaI bits, multiply by 2 ^ 8 (256), resalting in 384. Addition and subtraktion are straightforward, but t multiglication and division exquiirements to maintain the scalpe.
