Multi-level dataflow-driven macro placement guided by RTL structure and analytical methods
(2021-12)
Article
Accés obertWhen RTL designers define the hierarchy of a system, they exploit their knowledge about the conceptual abstractions devised during the design and the functional interactions between the logical components. This valuable ... -
Multicore Early Design Stage Guaranteed Performance Estimates for the Space Domain
(IEEE, 2019-05-16)
Comunicació de congrés
Accés obertThe ability to produce early guaranteed performance (worst-case execution time) estimates for multicores, i.e. before software from different providers gets integrated onto the same critical system, is pivotal. This helps ... -
Non-data-aided frequency offset and symbol timing estimation for binary CPM: performance bounds
(Institute of Electrical and Electronics Engineers (IEEE), 2000)
Text en actes de congrés
Accés obertThe use of (spectrally efficient) CPM modulations may lead to a serious performance degradation of the classical non-data-aided (NDA) frequency and timing estimators due to the presence of self noise. The actual performance ... -
