What is meant by saturation arithmetic?
Saturation arithmetic is a version of arithmetic in which all operations, such as addition and multiplication, are limited to a fixed range between a minimum and maximum value.
What does it mean to saturate to 0?
When the saturation is zero, what you will see is a shade of gray. However, saturation does not define how light or dark a color is. Although many saturated colors tend to be lighter than less saturated ones, adding white to the latter will increase their brightness until both values will match.
What is saturation in DSP?
• Saturation is a fundamental method to reduce the size of a word, such as after arithmetic operations. – For example to maintain the word width for memory storage. • When saturated, bits are removed from the MSB end of the input word. +
What is saturating arithmetic and what are its advantages and disadvantages in typical multimedia applications?
What is saturating arithmetic and how does it help? Saturating arithmetic eliminates the need for overflows and underflows on MMX instructions. If a result is out of bounds, it is saturated to the closest allowable value. Many multimedia applications benefit from saturating arithmetic by avoiding wraparound artifacts.
