The x86 instruction set has several times been extended with SIMD (Single instruction, multiple data) instruction set extensions.These extensions, starting from the MMX instruction set extension introduced with Pentium MMX in 1997, typically define sets of wide registers and instructions that subdivide these registers into fixed-size lanes and perform a computation for each lane in parallel.
SSE contains 70 new instructions (65 unique mnemonics [1] using 70 encodings), most of which work on single precision floating-point data. SIMD instructions can greatly increase performance when exactly the same operations are to be performed on multiple data objects. Typical applications are digital signal processing and graphics processing.
existing instructions extended to a 64 bit address size (JRCXZ) existing instructions extended to a 64 bit operand size (remaining instructions) Most instructions with a 64 bit operand size encode this using a REX.W prefix; in the absence of the REX.W prefix, the corresponding instruction with 32 bit operand size is encoded. This mechanism also ...
Roast until the pork is lightly browned and about halfway cooked through, 10 to 12 minutes. (A thermometer inserted near the bone should read over 100˚). Switch the oven to broil.
AVX-512 are 512-bit extensions to the 256-bit Advanced Vector Extensions SIMD instructions for x86 instruction set architecture (ISA) proposed by Intel in July 2013, and first implemented in the 2016 Intel Xeon Phi x200 (Knights Landing), [1] and then later in a number of AMD and other Intel CPUs (see list below).
6 pork chop, 3/4-inch thick (about 2 pounds); 1 jar (24 ounces) Prego® Fresh Mushroom Italian Sauce; 6 cup medium tube-shaped pasta (ziti) or spaghetti, cooked and drained
While what these instructions do is similar to bit level gather-scatter SIMD instructions, PDEP and PEXT instructions (like the rest of the BMI instruction sets) operate on general-purpose registers. [12] The instructions are available in 32-bit and 64-bit versions. An example using arbitrary source and selector in 32-bit mode is:
Cook for 1 1/2 to 2 hours, turning the pork twice during cooking (once after 45 minutes and again after an hour and a half). Raise the temperature to 425°F. Uncover the Dutch oven and add the olives.
