The first problem is wasted work again. If cell A1 references B8, and cell A2 also references B8, then when we update all the cells, we still only want to evaluate B8 once, and then reference it in both A1 and A2. We can do this through caching — whenever we calculate a cell’s value, we store it somewhere, and then all future cell references can used the stored value instead of recalculating.
“A commercial product delivering megabit data rates can be envisioned within a few years of development. Here in Sydney we have the semiconductor equipment we need to produce the next-generation prototypes of this device at the Australian National Fabrication Facility on the UNSW campus,” said Prof. Ekins-Daukes.
