3. Model-specific register - Wikipedia

   en.wikipedia.org/wiki/Model-specific_register

   Use of the Linux msr kernel module creates a pseudo file "/dev/cpu/x/msr" (with a unique x for each processor or processor core). A user with permissions to read and/or write to this file can use the file I/O API to access these registers. The msr-tools [6] package provides a reference implementation.

5. x86 Bit manipulation instruction set - Wikipedia

   en.wikipedia.org/wiki/X86_Bit_manipulation...

   AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions. AMD today advertises the availability of these features via Intel's BMI1 and BMI2 cpuflags and instructs programmers to target them accordingly. [2]

6. FMA instruction set - Wikipedia

   en.wikipedia.org/wiki/FMA_instruction_set

   The four-operand form (FMA4) allows a, b, c and d to be four different registers, while the three-operand form (FMA3) requires that d be the same register as a, b or c. The three-operand form makes the code shorter and the hardware implementation slightly simpler, while the four-operand form provides more programming flexibility.

7. Bulldozer (microarchitecture) - Wikipedia

   Piledriver is the AMD codename for its improved second-generation microarchitecture based on Bulldozer. AMD Piledriver cores are found in Socket FM2 Trinity and Richland based series of APUs and CPUs and the Socket AM3+ Vishera based FX-series of CPUs. Piledriver was the last generation in the Bulldozer family to be available for socket AM3 ...
