On-chip networks for future system-on-chip designs need simple, high performance implementations. In order to promote system-level integrity, guaranteed services (GS) need to be provided. We propose a network-on-chip (NoC) router architecture to support this, and demonstrate with a CMOS standard cell design. Our implementation is based on clockless circuit(More)
This paper presents a Network-on-Chip (NoC) architecture that enables the network topology to be reconfigured. The architecture thus enables a generalized System-on-Chip (SoC) platform in which the topology can be customized for the application that is currently running on the chip, including long links and direct links between IP-blocks. The(More)
This paper describes the design and VLSI implementation of a delay insensitive circuit that computes the inner product of two vectors. The circuit is based on an iterative serial-parallel multiplication algorithm. A test chip has been fabricated via BUROCHIP. The circuit is the result of a design experiment that we have conducted as part of our ongoing work(More)
Real-time systems need time-predictable platforms to allow static analysis of the worst-case execution time (WCET). Standard multi-core processors are optimized for the average case and are hardly analyz-able. Within the T-CREST project we propose novel solutions for time-predictable multi-core architec-tures that are optimized for the WCET instead of the(More)
— In this paper, we present an area-efficient, globally asynchronous, locally synchronous network-on-chip (NoC) architecture for a hard real-time multiprocessor platform. The NoC implements message-passing communication between processor cores. It uses statically scheduled time-division multiplexing (TDM) to control the communication over a structure of(More)
Abstrucf-Recent research has demonstrated that for certain types of applications like sampled audio systems, self-timed circuits can achieve very low power consumption, because unused circuit parts automatically turn into a stand-by mode. Additional savings may be obtained by combining the self-timed circuits with a mechanism that adaptively adjusts the(More)
—This paper explores the design of a circuit-switched network-on-chip (NoC) based on time-division-multiplexing (TDM) for use in hard real-time systems. Previous work has primarily considered application-specific systems. The work presented here targets general-purpose hardware platforms. We consider a system with IP-cores, where the TDM-NoC must provide(More)
—This paper investigates how a lightweight , statically scheduled network-on-chip (NoC) for real-time systems can be designed and implemented. The NoC provides communication channels between all cores with equal bandwidth and latency. The design is FPGA-friendly and consumes a minimum of resources. We implemented a 64 core 16-bit multiprocessor connected(More)
