Classical Stochastic Computing methods perform operations on bit streams generated using random number generators. Sufficient accuracy requires long bit streams which leads to very high latency and larger area. Deterministic approaches to Stochastic

Fully integrated CMOS frequency-modulated continuous-wave radar ICs are under development, in which computing FFTs cost a significant amount of energy. In this paper we introduce a power-efficient FFT solution which exploits that intermediate results

Cyber-physical control systems are typically time-triggered because the Analog to Digital (A/D) and Digital to Analog (D/A) converters are triggered by a periodic clock. This enables analytical stability analysis of closed-loop models in case the pla

Self-Timed Scheduling Analysis for Real-Time Applications

Autor: Moreira Orlando M, Bekooij Marco JG

Publikováno v: EURASIP Journal on Advances in Signal Processing, Vol 2007, Iss 1, p 083710 (2007)

This paper deals with the scheduling analysis of hard real-time streaming applications. These applications are mapped onto a heterogeneous multiprocessor system-on-chip (MPSoC), where we must jointly meet the timing requirements of several jobs. Each

Sampling Jitter mitigation in latency-critical state-estimation applications using particle filters

Autor: El Hakim, Viktorio Semir, Bekooij, Marco Jan Gerrit

Publikováno v: 2017 SICE International Symposium on Control Systems

State estimation algorithms, such as the Kalman filter, are applied for conditioning and sensor fusion in digital control loops. It is desirable that these algorithms can be executed on embedded multiprocessor systems. However this results in large w
