Since bit-slice designs often must pass information from bit-slice to bit-slice, the delay between a change in operand bit0 and a resulting change on the most-significant result bit may be too long to be useful in any given circuit. philippines ncaa men\u0027s basketball

"Bit slicing is a technique for constructing a processor from modules of processors of smaller bit width, for the purpose of increasing the word length; in theory to make an arbitrary n-bit central processing unit (CPU). Each of these component modules processes one bit field or "slice" of an operand. The grouped processing components would then have the capability to process the chosen full word-length of a given software design. " - Bit slice indexing

WebThe half-openness of a slice may seem awkward at first, but it helps to avoid one-off count issues in practice. For example, the slice a[8:] has exactly 8 bits. Likewise, the slice a[7:2] has 7-2=5 bits. You can think about it as follows: for a slice [i:j], only bits below index i are included, and the bit with index j is the last bit included.
