Heterogeneous integration facilitates faster design cycles with optimal functional IP module and silicon node combinations, but requires ultra-high bandwidth for the die-to-die communications. Fine pitch interconnects can meet such high bandwidth demands with simpler circuits, lower power and less latency. Hence, it is of utmost importance to understand the performance of these interconnects at different speeds and channel lengths. This paper focuses on a parametric study over the basic design parameters of a generic fine pitch interconnect, to explore the electrical performance limits. As a result of this study, practical guidelines are provided for the die-to-die channel design.

Dalkiran, Emre; Onel, Tolga; Oğuztüzün, Mehmet Halit S.; Demir, Kadir Alpaslan (2021-04-01)
Various application domains require the integration of distributed real-time or near-real-time systems with non-real-time systems. Smart cities, smart homes, ambient intelligent systems, or network-centric defense systems are among these application domains. Data Distribution Service (DDS) is a communi-cation mechanism based on Data-Centric Publish-Subscribe (DCPS) model. It is used for distributed systems with real-time operational constraints. Java Message Service (JMS) is a messaging standard for enterpr...
Estimation of partially observed multiple graph signals by learning spectrally concentrated graph kernels
Turhan, Gülce; Vural, Elif; Department of Electrical and Electronics Engineering (2021-3-31)
Graph models provide flexible tools for the representation and analysis of signals defined over domains such as social or sensor networks. However, in real applications data observations are often not available over the whole graph, due to practical problems such as broken sensors, connection loss, or storage problems. In this thesis, we study the problem of estimating partially observed graph signals on multiple graphs. We consider possibly multiple graph domains over which a set of signals is available wi...
Differential network coding in wireless networks Telsiz aǧlarda farksal aǧ kodlamasi
Özdemir, Özgür; Yılmaz, Ali Özgür (2009-10-29)
In this paper a three-terminal communication scenario where two users exchange information by employing differential binary modulation and network coding via a relay is considered. The transmission is divided into three slots in time where the first and second slots are allocated to the transmission of differential encoded data of the users. After demodulation, the relay broadcasts the bit-wise XOR-ed and differential encoded packet to the users in the third slot. The optimum detector and a simplified decis...
Broadband MLFMA based on an approximate diagonalization of the three-dimensional Green's function
Ergül, Özgür Salih (2015-09-11)
We present an approximate diagonalization of the three-dimensional Green's function for straightforward broadband implementations of the multilevel fast multipole algorithm. The diagonalization is based on the use of scaled spherical functions and plane waves, leading to approximate but stable expansions for arbitrarily short distances with respect to wavelength. Despite its limited accuracy, the approximate diagonalization is easy to insert into existing MLFMA implementations for converting them into broad...
Relay Selection for Efficient HARQ-IR Protocols in Relay-Assisted Multisource Multicast Networks
Quoc-Tuan Vien, Quoc-Tuan Vien; Nguyen, Huan X.; Shah, Purav; Ever, Enver; Duc To, Duc To (2014-05-21)
This paper investigates relay selection for reliable data transmission in relay-assisted multisource multicast networks (RMMNs) where multiple source nodes distribute information to a set of destination nodes with the assistance of multiple relay nodes. Hybrid automatic repeat request with incremental redundancy (HARQ-IR) is used and supported by either a physical-layer network coding (PNC) or an analog network coding (ANC) technique employed at the relays. By deriving efficiency metrics of the HARQ-IR prot...
