The Von Neumann bottleneck is the inability of the sequential one-instruction-at-a-time computer Von Neumann model to handle today's large-scale problems. If nothing were done, the CPU would spend most of its time waiting around for … Memory locations are stored in row major order. It can't write the data value of the previous instruction whilst being fed new instructions, which slows the processor down. Brain evolution in Homo: The “radiator” theory1 - Volume 13 Issue 2 - Dean Falk The “radiator” theory of brain evolution is proposed to account for “mosaic evolution” whereby brain size began to increase rapidly in the genus Homo well over a million years after bipedalism had been selected for in early hominids.
