+# Big Picture
+
+*(circa Q1 2012)*
+
+The generic term "System on a Chip" refers to the fact that the CPU and many
+"peripherals" (USB, ethernet, memory controller, GPU) are integraded into a
+single package instead of being distributed across a motherboard via a
+northbridge and southbridge. There still needs to be external analog and
+digital circuitry for most "connectivity" interfaces like USB or ethernet to
+provide level conversion, isolation, etc. Notably, RAM is not usually
+integraded into the chip, and the large parallel bus to the RAM chips must be
+routed very carefully. Some newer chips (popular circa 2010?) include "package
+on package" technology where the RAM chip is right on top of the SoC to make
+routing easier (eg, iPhones, RaspberryPI).
+
+The establishment players for mobile ARM SoCs are TI (OMAP), Qualcomm
+([http://en.wikipedia.org/wiki/Snapdragon_(System_on_Chip)](Snapdragon), not
+regular ARM), Samsung ([http://en.wikipedia.org/wiki/Exynos](Exynos))), Broadcom (Armada, Armada XP, )
+
+The establishment players for MIPS SoCs are Broadcom and Marvell (Kirkwood).
