SoC Methodology SoC Methodology OverviewOverview Component-based SoC design:

– It starts with a set of components and provides a set of primitives to build application-specific architectures and communication links.

The key idea is to increase the abstraction level when designing component interconnections.

It may provide a considerable reduction of design time for hardware/software communication refinement and component integration and may facilitate IP reuse.

MultiProcessor SoC MultiProcessor SoC trendstrends The topologies for interconnecting

multiple processors consist of simple bus structures, dual-ported memories linking processors, and on-chip processor communication networks.

Design-space exploration through the simulation of various multi-processor system designs is essential to choosing the right connection topology in these systems.

Interconnection Network Interconnection Network ArchitectureArchitecture The shared-bus based communication

architecture topology is popular choices for on-chip communication between components.

The architecture usually consists of several shared busses interconnected by bridges to form a hierarchy.

Different levels of the hierarchy correspond to the varying communication bandwidth requirement of SoC components.

TM32 is a high performance very long instruction word (VLIW) processor specially optimized for communication or multimedia signal applications.

It can issue at 5 instructions at the same time.

The maximum clock frequency is 400MHZ. It has 128×32-bit general-purpose

registers and on-chip hardware support for audio-video I/O.

Performance evaluationPerformance evaluation

ConclusionConclusion In this paper, we have presented the

micro-architecture of the Nexperia8500. TM32 has more better performance

because it has more registers. MPSoC integration enables large

improvements in processor performance, cost/performance, floor space, and total power consumed over previous processor.
