1. Introduction
High-performance processor design has recently taken two distinct approaches. One approach is to increase the execution rate by increasing the clock frequency of the processor or by reducing the execution latency of the operations. While this approach is important, much of its performance gain comes as a consequence of circuit and layout improvements and is beyond the scope of this research. The other approach is to directly exploit the instruction-level parallelism (ILP) in the program and to issue and execute multiple operations concurrently. This approach requires both compiler and microarchitecture support.
Traditional processor designs that issue and execute at most one operation per cycle are often called scalar designs. Static and dynamic scheduling techniques have been used to achieve better-than scalar performance by issuing and executing more than one operation per cycle. While Johnson[7] defines a superscalar processor as a design that achieves better-than scalar performance, popular usage of this term refers exclusively to those processors that use dynamic scheduling techniques. For clarity, we use instruction-level parallel processors to refer to the general class of processors that execute more than one operation per cycle of the computer both at the personal level, or the level of a small network of computers to do not require more of these types.
The primary static scheduling technique uses the compiler to determine sets of operations that have their source operands ready and have no dependencies within the set. These operations can then be scheduled within the same instruction subject only to hardware resource limits. Since each of the operations in an instruction is guaranteed by the compiler to be independent, the hardware is able to is- sue and execute these operations directly with no dynamic analysis. These multi-operation instructions are very long in comparison with traditional single-operation instructions and processors using .
An octa core processor with shared memory and message-passingeSAT Journals
Abstract This being the era of fast, high performance computing, there is the need of having efficient optimizations in the processor architecture and at the same time in memory hierarchy too. Each and every day, the advancement of applications in communication and multimedia systems are compelling to increase number of cores in the main processor viz., dual-core, quad-core, octa-core and so on. But, for enhancing the overall performance of multi processor chip, there are stringent requirements to improve inter-core synchronization. Thus, a MPSoC with 8-cores supporting both message-passing and shared-memory inter-core communication mechanisms is implemented on Virtex 5 LX110T FPGA. Each core is based on MIPS III (Microprocessor without interlocked pipelined stages) ISA, handling only integer type instructions and having six-stage pipeline with data hazard detection unit and forwarding logic. The eight processing cores and one central shared memory core are inter connected using 3x3 2-D mesh topology based Network-on-chip (NoC) with virtual channel router. The router is four stage pipelined supporting DOR X-Y routing algorithm and with round robin arbitration technique. For verification and functionality test of above fully synthesized multi core processor, matrix multiplication operation is mapped onto the above said. Partitioning and scheduling of multiple multiplications and addition for each element of resultant matrix has been done accordingly among eight cores to get maximum throughput. All the codes for processor design are written in Verilog HDL. Keywords: MPSoC, message-passing, shared memory, MIPS, ISA, wormhole router, network-on-chip, SIMD, data level parallelism, 2-D Mesh, virtual channel
HOMOGENEOUS MULTISTAGE ARCHITECTURE FOR REAL-TIME IMAGE PROCESSINGcscpconf
In this article, we present a new multistage architecture oriented to real-time complex processing applications. Given a set of rules, this proposed architecture allows the using of different communication links (point to point link, hardware router…) to connect unlimited number of parallel computing elements (software processors) to follow the increasing complexity of algorithms. In particular, this work brings out a parallel implementation of multihypothesis approach for road recognition application on the proposed Multiprocessor Systemon-Chip (MP-SoC) architecture. This algorithm is usually the main part of the lane keeping applications. Experimental results using images of a real road scene are presented. Using a low cost FPGA-based System-on-Chip, our hardware architecture is able to detect and recognize the roadsides in a time limit of 60 mSec. Moreover, we demonstrate that our multistage architecture may be used to achieve good speed-up in solving automotive applications.

Concurrent Matrix Multiplication on Multi-core ProcessorsCSCJournals
With the advent of multi-cores every processor has built-in parallel computational power and that can only be fully utilized only if the program in execution is written accordingly. This study is a part of an on-going research for designing of a new parallel programming model for multi-core architectures. In this paper we have presented a simple, highly efficient and scalable implementation of a common matrix multiplication algorithm using a newly developed parallel programming model SPC3 PM for general purpose multi-core processors. From our study it is found that matrix multiplication done concurrently on multi-cores using SPC3 PM requires much less execution time than that required using the present standard parallel programming environments like OpenMP. Our approach also shows scalability, better and uniform speedup and better utilization of available cores than that the algorithm written using standard OpenMP or similar parallel programming tools. We have tested our approach for up to 24 cores with different matrices size varying from 100 x 100 to 10000 x 10000 elements. And for all these tests our proposed approach has shown much improved performance and scalability

MICROARCHITECTURE OF A COARSE-GRAIN OUT-OF-ORDER
SUPERSCALAR PROCESSOR
ABSTRACT:
We explore the design, implementation, and evaluation of a coarse-grain superscalar processor in
the context of the microarchitecture of the Control Processor (CP) of the Multilevel Computing
Architecture (MLCA), a novel architecture targeted for multimedia multicore systems. The
MLCA augments a traditional multicore architecture (called the lower level) with a CP (called
the top-level), which automatically extracts parallelism among coarse-grain units of computation
(tasks), synchronizes these tasks and schedules them for execution on processors. It does so in a
fashion similar to how instruction-level parallelism is extracted by superscalar processors, i.e.,
using registers renaming, Out-of-Order Execution (OoOE) and scheduling. The coarse-grain
nature of tasks imposes challenging constraints on the direct use of these techniques, but also
offers opportunities for simpler designs.
We analyze the impact of these constraints and opportunities and present novel
microarchitectural mechanisms for coarse-grain superscalar execution, including register
renaming, task queue, dynamic out-of-order scheduling and task-issue. We design an MLCA
system around our CP microarchitecture and implement it on an FPGA. We evaluate the system
using multimedia applications and show good scalability for eight processors, limited by the
memory bandwidth of the FPGA platform. Furthermore, we show that the CP introduces little
overhead in terms of resource usage. Finally, we show scalability beyond eight processors using
cycle-accurate RTL-level simulation with an idealized memory subsystem. We demonstrate that
the CP poses no performance bottlenecks and is scalable up to 32 processors.
