AMD has finally confirmed the movement towards developing a new x86-compatible micro-Zen, which appears in the form of central processing units in 2016-2017 and will be distributed in parallel proprietary ARM-compatible architecture K12. The processor is designated as znver1. Processors is based on the architecture Bulldozer.
An important feature after studying the content of patches is that Zen architecture no longer supports instruction Bulldozer: TBM, FMA4, XOP or LWP ISA. It really is a new architecture and code optimization for Zen (for AMD platforms) is different from that in the past and present. For future generations AMD solutions Zen programmers need to learn instructions ISA, SMAP, RDSEED, SHA, XSAVEC, XSAVES, CLFLUSHOPT and ADCX. However, they are used for the latest generation of Intel processors , including Broadwell generation solutions .
Also AMD Zen architecture will support the new instructions CLZERO. Support information entered in the Zen Binutils last week. Patches to support Zen compilers GCC and LLVM / Clang will be published in the coming months. Developers must meet with the changes long before the new computing platform.
