What will happen in the future to processors.
Future embedded processors will be a combination of the unknown and known technologies. The unknown because they'll be decorated with coprocessors and accelerators, intrachip networks, elaborate value speculation, unfathomable branch prediction, enormous multilevel caches, and inscrutable instruction sets. The known because old embedded processors never die. Expect to see 8051s, Z80s, and more descendants of the x86 line soldier on in low-end systems.
