 332 <p>Access to dedicated SIMD instructions available on Armv7E-M (Cortex-M4/M7), Armv8-M Mainline (Cortex-M33/M35P), and Armv8.1-M (Cortex-M55/M85). </p>
 333 <p><b>Single Instruction Multiple Data (SIMD)</b> extensions are provided <b>only for Cortex-M4 and Cortex-M7 cores</b> to simplify development of application software. SIMD extensions increase the processing capability without materially increasing the power consumption. The SIMD extensions are completely transparent to the operating system (OS), allowing existing OS ports to be used.</p>
 334 <p><b>SIMD Features:</b></p>
 335 <ul>
 336 <li>Simultaneous computation of 2x16-bit or 4x8-bit operands</li>
 337 <li>Fractional arithmetic</li>
 338 <li>User definable saturation modes (arbitrary word-width)</li>
 339 <li>Dual 16x16 multiply-add/subtract 32x32 fractional MAC</li>
 340 <li>Simultaneous 8/16-bit select operations</li>
 341 <li>Performance up to 3.2 GOPS at 800MHz</li>
 342 <li>Performance is achieved with a "near zero" increase in power consumption on a typical implementation</li>
