Constant bandwidth servers with constrained deadlines [PDF]
Proceedings of the 25th International Conference on Real-Time Networks and Systems, 2017 The Hard Constant Bandwidth Server (H-CBS) is a reservation-based scheduling algorithm often used to mix hard and soft real-time tasks on the same system.

Co-Design of BW-Enhanced Dual-Path Driver and Segmented Microring Modulator for Energy Efficient Si-Photonic Transmitters [PDF]
MicromachinesArtificial intelligence computing systems increasingly demand high-bandwidth, high-extinction-ratio, chip-to-chip optical transceivers. Silicon microring modulators (MRMs) are attractive for such transmitters due to their compact footprint and wavelength-

Optimal Dimensioning of a Constant Bandwidth Server [PDF]
2006 27th IEEE International Real-Time Systems Symposium (RTSS'06), 2006 The Constant Bandwidth Server (CBS) is an effective scheduling technique frequently used to handle overruns and implement resource reservation in real-time systems where tasks have variable execution requirements. The behavior of the server is tuned by two parameters: the server bandwidth, which defines the fraction of the processor allocated to the ...

Tunable lumped-element bandpass filters with constant bandwidth
Известия высших учебных заведений России: Радиоэлектроника, 2015 Lumped-element bandpass filters using LC-tanks and immittance inverters are considered. Tuning of the central frequency is provided by using variable capacitors of LC-tanks and immittance inverters.

Design of Tunable Coaxial Bandpass Filter Based on Embedded Stepped Impedance Resonators
IEEE Access, 2023 This paper describes a method for designing tunable coaxial bandpass filters based on an inserted coaxial stepped impedance resonator (SIR). The miniaturization of the coaxial resonator is realized by the shape of the stepped impedance structure.

Constant bandwidth server revisited [PDF]
ACM SIGBED Review, 2015 The Constant Bandwidth Server (CBS) is an algorithm for providing temporal protection and real-time guarantees to real-time sporadic tasks. Recently, an implementation of this algorithim called SCHED_DEADLINE has been included in the Linux kernel. Therefore, the CBS algorithm is now used to serve more generic tasks than do not obey to the classical ...

Migrating Constant Bandwidth Servers on Multi-Cores [PDF]
29th International Conference on Real-Time Networks and Systems, 2021 This paper introduces a novel admission test for partitioned CBS reservations on multi-core systems, that, on a new reservation arrival, is capable of exploiting better the CPU capacity in cases in which tasks have just recently left the CPU (for example, due to termination or migration to a different CPU).
