The number of logical processors (processors that the operating system and applications can work with) is (usually) greater or equal to the number of physical processors (actual processors on the motherboard). For example, a hyperthreaded processor with 4 physical processors will have 8 logical processors.
Usually, during the initial 6-months of pregnancy (that is 1 st & 2 nd trimesters), you will not have the need to consume more calories. This is usually about 2000-calories per day. On the other hand, the last 3 months of pregnancy (that is 3 rd trimester), you need additional 200 to 300-calories, which makes it to 2200 to 2300-calories per day.
The rule of thumb is most women need about 300 extra calories every day during the last five to six months of pregnancy for good fetal development. This will combine to a healthy weight gain of about one pound each week. If you consume too few calories your body may begin to take the calories from stores that are needed for healthy pregnancy weigh gain and baby development. Replenish the calories you burn by doing moderately intense cardio exercise every week.
