Carry bit

It is natural to model a carry by simply using the result size to be one bit larger than the largest of the two operands. Alternatively, a concatenation could also be used as the target of an assignment with the carry bit explicitly specified. Here are examples of these. 

In the first continuous assignment, the result of the operation is five bits and OneUp[4] has the carry bit. If OneUp were declared as ... 

The falcon s beak carries bits of me, myself," the desert said. "For years, I care for his game, feeding it with the little water that I have, and then I show him where the game is. And, one day, as I enjoy the fact that his game thrives on my surface, the falcon dives out of the sky, and takes away what I ve created."... 

The DG will be completely specified when the exact position of the nodes and the interconnecting edges are determined. The number of the nodes of the DG should be specified first. Let Ai be the number of nodes contributing to the computation of the tth output bit, ft. Also, let 0i be the number of bits that should be added by the Ai nodes. The Pi bits include the bits specified by equation (17), and the carry bits that result from the computation of the (i — l)th output bit. It can be noticed that the number of carry bits coincides with the number Ai i. Hence ... 

Well, maybe bilingual, because DNA and RNA are basically the same language. Each letter of DNA and RNA is only different by two atoms distant from the information-carrying bits. Two strands of DNA and RNA made with the same letters will easily align with each other if you mix them in a tube. 

Figure 1.4 Half-adder circuit. A and B are input bits, S the sum and C the carry bit, which is not used in this...

Notice that the output S is just the XOR output, which in turn is the addition of two bits, and the output C is the carry bit. 

The signal ANSWER has been given an extended range so that the output contains an extra bit. However, this fifth bit is not interpreted as a carry bit by the synthesizer and is instead merged with the fourth bit, which it considers is the most significant... 

Each nucleus in a living ceU contains long, thread-like structures called chromosomes, which carry bits of genes. Both chromosomes and genes are made of DNA, which is often called the blueprint for life every living cell contains indeed a copy of the blueprint. 

Fig. 4.13 Schematic diagram of the operation of the carry-ripple adder of Stei-glitz, Kamal, and Watson. The particle-bundles (pairs of particles) encode the bits of the two addends, and are labeled A (0,0), B (0,1 or 1,0), and C (1,1). The fast particle, labeled F, effects the addition of each pair of addends. Afer collision with F, the particle bundles encode the result for each added pair, and F propagates the carry bit from each pairwise addition. (Adapted from Steiglitz, Kamal, and Watson, 1988.)...
