All about APX conditional ISA
Motivation Somtimes branch mispredictions are a major performance limiter in workloads. The bottleneck is data-dependent conditional branches and hard to mit...
All about APX JMPABS
Why do we need JMPABS? JMPABS, which, as the name already suggests, allows jumping to a 64-bit absolute address. Before APX, X86 has 32-bit displacement limi...
All about APX relocation
REX2 Intel® APX introduces a new 2-byte REX2 prefix in order to support 32 general-purpose registers (GPRs).
