Designing SOCs with Configured Cores. Unleashing the by Steve Leibson

By Steve Leibson

  • Designing SOCs with Configured Processor Cores is a necessary reference for system-on-chip designers. This well-written booklet supplies a pragmatic advent to 3 easy strategies of recent SOC layout: use of optimized usual CPU and DSP processors cores, application-specific configuration of processor cores, and system-level layout of SOCs utilizing configured cores because the key development block. Readers will locate it's always the 1st publication they achieve for in defining and designing their subsequent chip. — Chris Rowen, President and CEO, Tensilica, Inc. we are poised near to a revolution in computing. rather than fixed-architecture processors acceptable merely to general-purpose computing or special-purpose electronic sign processing initiatives, we are relocating to system-on-chip (SoC) units containing a number of processor cores, every one configured to accomplish particular initiatives with severe functionality whereas eating ultra-low strength. The surf is up - and this publication tells us the best way to journey the wave! — Clive “Max” Maxfield, President, TechBites Interactive and writer of The layout Warrior’s advisor to FPGAs Steve Leibson's ebook is a gradual creation to the paintings of electronic electronics layout taking pictures a massive second within the construction of the total method on a chip. Generously dotted with block diagrams and snippets of code utilizing the automobile offered through Xtensa expertise, the booklet takes the reader during the evolution that ended in a number of cores and configurable engines. — Max Baron, Senior Analyst on the Microprocessor file

FM8501: A Verified Microprocessor

The FM 8501 microprocessor was once invented as a common microprocessor slightly just like a PDP-11. The critical suggestion of the FM 8501 attempt used to be to work out if it was once attainable to precise the user-level specification and the layout implementation utilizing a proper common sense, the Boyer-Moore common sense; this procedure accepted a whole automatically checked evidence that the FM 8501 implementation totally applied its specification.

Code Optimization Techniques for Embedded Processors: Methods, Algorithms, and Tools

The development blocks of brand new and destiny embedded structures are advanced highbrow estate parts, or cores, a lot of that are programmable processors. regularly, those embedded processors regularly were seasoned­ grammed in meeting languages because of potency purposes. this means time­ eating programming, large debugging, and occasional code portability.

Worst-Case Execution Time Aware Compilation Techniques for Real-Time Systems

For real-time structures, the worst-case execution time (WCET) is the main aim to be thought of. normally, code for real-time platforms is generated with no taking this goal into consideration and the WCET is computed simply after code new release. Worst-Case Execution Time acutely aware Compilation innovations for Real-Time structures provides the 1st finished strategy integrating WCET issues into the code new release method.

An Energy Efficient-Reconfigurable Circuit-Switched Network-onChip," International SOC Conference, Tampere, Finland, November 2005. CHAPTER 3 XTENSA ARCHITECTURAL BASICS Anyone can build a fast CPU. The trick is to build a fast system. mSeymour Cray Academic researchers, system-on-chip (SOC) designers, and ASIC and EDA vendors are in a fair a m o u n t of agreement as to what must be done to reduce SOC design risks. SOC designs m u s t become flexible enough to a c c o m m o d a t e design changes brought on by design errors, spec changes, standards changes, and competitive market forces.

Ultimately, the Manual concludes that the simple waterfall-development model simply does not work for more complex SOC designs. 2 shows an expanded ASIC design flow. 1 and shows the people involved at each design step, the tasks they perform, and the tools used to perform each of the tasks. This figure provides a better view into the steps needed to convert a system definition into a placed and routed netlist that is ready for chip fabrication. 1 lacked. 2 still falls short of showing an SOC design flow (as opposed to an ASIC design flow) because the entire SOC design occupies just one box--a task to be performed by the system architect.

13 PROCESSORS: THE ORIGINAL, REUSABLEDESIGN BLOCK Microprocessors became successful because they were the first truly universal, reusable block of logic to become available. 13 Processors: The Original, Reusable Design Block 27 reprogramming, microprocessors could be made to perform a very wide range of tasks with no changes to the hardware. This characteristic allowed system designers to use fixed-ISA, packaged processor ICs in an everexpanding n u m b e r of systems. As the popularity of these universal system building blocks grew, an entire software-development tool industry grew up around packaged microprocessors.
