Multiprocessing in Mobile Platforms: the Marketing and the Reality
Multiprocessing in Mobile Platforms: the Marketing and the Reality Marco Cornero, Andreas Anyuru ST-Ericsson Introduction During the last few years the mobile platforms industry has aggressively introduced multiprocessing in response to the ever increasing performance demanded by the market. Given the highly competitive nature of the mobile industry, multiprocessing has been adopted as a marketing tool. This highly visible, differentiating feature is used to pass the oversimplified message that more processors mean better platforms and performance. The reality is much more complex, because several interdependent factors are at play in determining the efficiency of multiprocessing platforms (such as the effective impact on software performance, chip frequency, area and power consumption) with the number of processors impacting only partially the overall balance, and with contrasting effects linked to the underlying silicon technologies. In this article we illustrate and compare the main technological options available in multiprocessing for mobile platforms, highlighting the synergies between multiprocessing and the disruptive FD-SOI silicon technology used in the upcoming ST-Ericsson products. We will show that compared to personal computers (PCs), the performance of single-processors in mobile platforms is still growing and how, from a software performance perspective, it is more profitable today to focus on faster dual-core rather than slower quad-core processors. We will also demonstrate how FD-SOI benefits dual-core processors even more by providing higher frequency for the same power consumption, together with a wider range of energy efficient operating modes. All of this results in a simpler, cheaper and more effective solution than competing homogeneous and heterogeneous quad-processors. -

Fax86: an Open-Source FPGA-Accelerated X86 Full-System Emulator
FAx86: An Open-Source FPGA-Accelerated x86 Full-System Emulator by Elias El Ferezli A thesis submitted in conformity with the requirements for the degree of Master of Applied Science (M.A.Sc.) Graduate Department of Electrical and Computer Engineering University of Toronto Copyright c 2011 by Elias El Ferezli Abstract FAx86: An Open-Source FPGA-Accelerated x86 Full-System Emulator Elias El Ferezli Master of Applied Science (M.A.Sc.) Graduate Department of Electrical and Computer Engineering University of Toronto 2011 This thesis presents FAx86, a hardware/software full-system emulator of commodity computer systems using x86 processors. FAx86 is based upon the open-source IA-32 full-system simulator Bochs and is implemented over a single Virtex-5 FPGA. Our first prototype uses an embedded PowerPC to run the software portion of Bochs and off- loads the instruction decoding function to a low-cost hardware decoder since instruction decode was measured to be the most time consuming part of the software-only emulation. Instruction decoding for x86 architectures is non-trivial due to their variable length and instruction encoding format. The decoder requires only 3% of the total LUTs and 5% of the BRAMs of the FPGA's resources making the design feasible to replicate for many- core emulator implementations. FAx86 prototype boots Linux Debian version 2.6 and runs SPEC CPU 2006 benchmarks. FAx86 improves simulation performance over the default Bochs by 5 to 9% depending on the workload. ii Acknowledgements I would like to begin by thanking my supervisor, Professor Andreas Moshovos, for his patient guidance and continuous support throughout this work. -

A given ISA may be implemented with different microarchitectures.[1] Implementations might vary due to different goals of a given design or due to shifts in technology.[2] Computer architecture is the combination of microarchitecture and instruction set design. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the execution model, processor registers, address and data formats among other things. The Intel Core microarchitecture microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detailed) diagrams that describe the interconnections of the various microarchitectural elements of the machine, which may be everything from single gates and registers, to complete arithmetic logic units (ALU)s and even larger elements. -
