This implies that the worst-case execution time (WCET) must be analyzed and bounded at design time. This is currently feasible for simple processors with an instruction cache, where hits and misses can be predicted. However, the WCET remains unacceptably overestimated for complex processors or conventional data caches. Hence, current hard real-time systems either use simple processors without caches, or oversized architectures.<\/p>\n<p>Our research group studies both WCET analysis methods and predictable memory hierarchies whose worst-case behavior can be accurately analyzed.<\/p>\n<\/div>\n<\/div><\/div><div id=\"panel-gb3638-6a328b84b76a2-0-0-1\" class=\"so-panel widget widget_sow-image panel-last-child\" data-index=\"1\" ><div\n\t\t\t\n\t\t\tclass=\"so-widget-sow-image so-widget-sow-image-default-8b5b6f678277-3638\"\n\t\t\t\n\t\t>\n<div class=\"sow-image-container\">\n\t\t<img \n\tsrc=\"https:\/\/gaz.i3a.es\/wp-content\/uploads\/2023\/01\/magnetic_core_memory_8k_12bit.png\" width=\"1080\" height=\"810\" srcset=\"https:\/\/gaz.i3a.es\/wp-content\/uploads\/2023\/01\/magnetic_core_memory_8k_12bit.png 1080w, https:\/\/gaz.i3a.es\/wp-content\/uploads\/2023\/01\/magnetic_core_memory_8k_12bit-300x225.png 300w, https:\/\/gaz.i3a.es\/wp-content\/uploads\/2023\/01\/magnetic_core_memory_8k_12bit-1024x768.png 1024w, https:\/\/gaz.i3a.es\/wp-content\/uploads\/2023\/01\/magnetic_core_memory_8k_12bit-768x576.png 768w, https:\/\/gaz.i3a.es\/wp-content\/uploads\/2023\/01\/magnetic_core_memory_8k_12bit-16x12.png 16w\" sizes=\"(max-width: 1080px) 100vw, 1080px\" alt=\"magnetic_core_memory_8k_12bit\" \t\tclass=\"so-widget-image\"\/>\n\t<\/div>\n\n<\/div><\/div><\/div><\/div><\/div>\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":3639,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[236],"tags":[],"class_list":["post-3638","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-lineas-de-investigacion"],"_links":{"self":[{"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/posts\/3638","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/comments?post=3638"}],"version-history":[{"count":2,"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/posts\/3638\/revisions"}],"predecessor-version":[{"id":3650,"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/posts\/3638\/revisions\/3650"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/media\/3639"}],"wp:attachment":[{"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/media?parent=3638"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/categories?post=3638"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaz.i3a.es\/es\/wp-json\/wp\/v2\/tags?post=3638"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
