In fact, applications running on such systems are usually known in advance and do not change over time. In a previous paper, we presented a profile-based code restructuring technique (CAT) that was able to dramatically increase cache exploitation of embedded applications.However, it is well known that profile-driven optimizations can suffer from input-sensitivity problems: an application that is optimized for a particular input can perform even worse than the original one, when subjected other inputs.In this paper we take into account jpeg and mpeg compressor\/decompressor applications and analyze the input-sensitivity of CAT improved layouts over a wide range of inputs. The input sets were accurately determined through both black-box and white-box analysis of applications.We propose two metrics for measuring the input-sensitivity of application layouts, and show how our profile-driven code transformation technique is able to reduce the input-sensitivity of the considered applications up to 48% on caches ranging from 1 KByte to 8KByte.<\/jats:p>","DOI":"10.1145\/1024295.1024305","type":"journal-article","created":{"date-parts":[[2004,10,7]],"date-time":"2004-10-07T17:39:09Z","timestamp":1097170749000},"page":"70-77","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["A proposal for input-sensitivity analysis of profile-driven optimizations on embedded applications"],"prefix":"10.1145","volume":"32","author":[{"given":"S.","family":"Bartolini","sequence":"first","affiliation":[{"name":"Dipartimento di Ingegneria dell'Informazione, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.
