Such a many-core system requires high-performance interconnections to transfer data smart reliable network-on-chip the cores on the chip.

Traditional system components interface with the interconnection backbone via a bus interface. This interconnection backbone can be an on-chip bus or multilayer bus architecture. With the advent of many-core architectures, the bus architecture becomes the performance bottleneck of the on-chip interconnection framework.

In contrast, network on chip NoC becomes a promising on-chip communication infrastructure, which is commonly considered as an aggressive long-term approach for on-chip communications. Accordingly, this paper first discusses several common architectures and prevalent techniques that can deal well with the design issues of communication performance, power consumption, signal integrity, and system scalability in an NoC.

Finally, a novel bidirectional NoC BiNoC architecture with a dynamically self-reconfigurable bidirectional channel is proposed to break the conventional performance bottleneck caused by bandwidth restriction smart reliable network-on-chip conventional NoCs.

Introduction As the density of VLSI design increases, the smart reliable network-on-chip of each component in a system raises rapidly. Traditional bus-based communication schemes, which lack for scalability and predictability, are not capable to keep up with the increasing requirements of future SoCs in terms of performance, power, timing closure, scalability, and so on.

Networks on Chips: Structure and Design Methodologies

To meet the design productivity and signal integrity challenges of next-generation system designs, a structured and scalable interconnection architecture, network on chip NoChas been proposed recently to mitigate the complex smart reliable network-on-chip communication problem.

An application can be represented as a set of computational units that require a set of communication blocks to pass information smart reliable network-on-chip the units.

To distinguish the performance impact of these two major smart reliable network-on-chip, computation time is dominated by gate delay whereas communication time is dominated by wire delay. When the amount of computational units is low, the communication blocks can be done on an ad-hoc basis.

However, with the shrinking size of transistors in recent years, gate delay is ever decreasing with respect to wire delay.

Thus, we need a structured and scalable on-chip communication architecture to fit the increasingly complex applications on a single chip. This translates to the design of on-chip communications architecture as being more and more important and promotes the design concept from computation-centric design to communication-centric design.

System on chip SoC is an architectural smart reliable network-on-chip developed in the last few decades, in which a processor or few processors along with memory and an associated set of peripherals connected by busses are all implemented on a single chip.

Power-efficient processors combined with hardware accelerators are the preferred choice for most designers to deliver the best tradeoff between performance and power consumption, since computational power increases smart reliable network-on-chip according to the calculation of dynamic power dissipation [ 1 ].

Therefore, this trend dictates spreading the application tasks into multiple processing elements where 1 each processing element can be individually turned on or off, thereby saving power, 2 each processing element can run at its own optimized supply voltage and frequency, 3 it is easier to achieve load balance among processor cores and to distribute heat across the die, and 4 it can potentially produce lower die temperatures smart reliable network-on-chip improve reliability and smart reliable network-on-chip.

A communication scheme is composed of an interconnection backbone, physical interfaces, and layered protocols which make the on-chip communication take place among components on a MP-SoC or CMP. As the design complexity scales up, intrachip communication requirements are becoming crucial.

Data-intensive systems such as multimedia devices, mobile installations, and multiprocessor platforms need a flexible and scalable interconnection scheme to handle a huge amount of data transactions on chip. Customarily, dedicated point-to-point wires are adopted as sets of application-specific global on-chip links that connect the top-level modules.

However, as wire density smart reliable network-on-chip length grow with the system complexity, the communication architecture based on point-to-point wires becomes no more feasible due to its poor scalability and reusability. Specifically, as signals are carried by the global wires across a chip, these metal wires typically do not scale smart reliable network-on-chip length with technology.

Propagation delay, power smart reliable network-on-chip, and reliability will be the serious issues of global wires in deep submicron VLSI technology.

According smart reliable network-on-chip [ 2 ], as silicon technologies advance to 50 nm and beyond, global wires will take 6 to 10 cycles to propagate, which will then far outweigh gate delays and make cross-chip long wire timing difficult to meet.

Keeping track of the status in all elements and managing the global communication among top-level modules by a centralized way are no longer feasible.

However, on-chip bus allows only one communication transaction at a time according to the arbitration result; thus, the average communication bandwidth of each processing element is in inverse proportion to the total number of IP cores in a system. Implementing multiple on-chip buses in a hierarchical architecture or in a separated manner may alleviate this scalability constraint, but it requires application-specific grouping of processing elements and design of different communication protocols to meet the application requirements.

Furthermore, whenever a new application needs to be designed for, or a new set of peripherals needs to be added, a chip designed with only simple buses will lack means of efficiently determining feasibility, not to mention optimality [ 5 ]. In addition, attempts to guarantee quality of service QoS for system performance will be a manually intensive task.

Therefore, bus-based design needs to be exchanged with a method that is flexible, scalable, and reusable. Since the latest process smart reliable network-on-chip allows for more processors and smart reliable network-on-chip cores to be placed on a single chip, smart reliable network-on-chip emerging MP-SoC and CMP architectures, which demand high throughput, low latency, and reliable global communication services, cannot be met by current dedicated bus-based on-chip communication infrastructure.
