Sunzi said: We may distinguish six kinds of terrain, to wit: (1) Accessible ground; (2) entangling ground; (3) temporizing ground; (4) narrow passes; (5) precipitous heights; (6) positions at a critical time: Moore's Law is fading just as deep learning demands unprecedented compute cycles. The new chapter on domain-specific architectures documents a number of promising approaches and prophesies a rebirth in computer architecture. AVX-512 instructions using EVEX encode a predicate operand, the opmask registers contain one bit per element, i.e., 64 bits. Note that 16-bit addresses are not just because it comes first alphabetically, but because time has passed too long. Among the Five Emperors, there are no
