... propose an elegant addressing scheme and its routing algorithm. While maintaining the existing address scheme, it tackles the wastage problem and achieves no additional memory storage during a routing. ... 16 bits and is partitioned equally, every dimension will have the range of 0 and 255. Similarly, two address dimensions may be arbitrarily allocated—say, 10 bits for...

... approach achieves a good switching reduction if the transferred data are random and evenly distributed over the whole data range. For the wide data bus without evenly distributed random data, the same ... especially when the bus capacitance is very small. On the other hand, the load capacitance of the off-chip buses are usually very high, and when they reach two orders of magnitude lar...
