<a class=anchor href=#scheduling>#</a></h2><p>Scheduling is an optimisation which is used to run various instructions in parallel that are
independent to each other.</p><h2 id=operation-chaining>Operation Chaining
<a class=anchor href=#operation-chaining>#</a></h2><p>Operation chaining is an optimisation that can be added on to scheduling and allows for the
sequential execution of instructions in a clock cycle, while executing other instructions in
parallel in the same clock cycle.</p><h2 id=if-conversion>If-conversion
<a class=anchor href=#if-conversion>#</a></h2><p>If-conversion is an optimisation which can turn code with simple control flow into a single block
(called a hyper-block), using predicated instructions.</p><h2 id=functions>Functions
<a class=anchor href=#functions>#</a></h2><p>Functions are currently only inlined in Vericert, however, we are working on a proper interface to
integrate function calls into the hardware.</p></p></article><footer class=book-footer><div class="flex flex-wrap justify-between"></div></footer><div class=book-comments></div><label for=menu-control class="hidden book-menu-overlay"></label></div><aside class=book-toc><nav id=TableOfContents><ul><li><ul><li><a href=#scheduling>Scheduling</a></li><li><a href=#operation-chaining>Operation Chaining</a></li><li><a href=#if-conversion>If-conversion</a></li><li><a href=#functions>Functions</a></li></ul></li></ul></nav></aside></main></body></html>
