We at Chipworks will be reporting more details on the fingerprint sensor, M7 and the A7 in the coming week. Our team of industry experts are analysiing everything from the system level software and assemblies to the circuits and Process technology. As we have for the past 21 years, looking closely at the complex web of applicable Patents. Stay tuned. Tom @ Chipworks
It is simply a mystery how Apple and Samsung could be competitors and best of customers. You have Samsung make A7 chip which is there to knock-out Samsung products in the market. A unique case for business schools.
Noticed denser interconnects in the A7, perhaps to accommodate the 2x wider ( 64 bit ) data and address buses within more or less the same real estate. Chipworks could go back and take one more look at their teardown of the Exynos 5 ( 32 bit 8 core ) in the Samsung S4 phone and compare the interconnect w/ the A7 ( both 28 nm by Sam ). Performance can actually take a hit if interconnect conductors & dielectrics are shrunk too much since resistance & capacitance will go up and will become a larger factor as the transistors get faster & more efficient.
Blog Doing Math in FPGAs Tom Burke 23 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
