Processor design pdf

The decreasing cost of DSPs has made these sophisticated chips very attractive for a number of embedded and real-time applications, including automotive, telecommunications, medical imaging, and many others including even some games and home appliances.

However, developing embedded and real-time DSP applications is a complex task influenced by many parameters and issues. This introduction to DSP software development for embedded and real-time developers shows how to use digital signal processors efficiently in embedded and real-time systems. It covers software and firmware design principles, from processor architectures and basic theory to the selection of appropriate languages and basic algorithms. The reader will find practical guidelines, diagrammed techniques, tool descriptions, and code templates for developing and optimizing DSP software and firmware.

The accompanying CDROM contains the code from the design examples as well as design tools and product demos. The LISA processor design platform presented in this book addresses recent design challenges and results in highly satisfactory solutions, covering all major high-level phases of embedded processor design.

In the past, embedded engineers needed to utilize a combination of traditional microcontrollers and DSP's digital signal processors in order to produce optimal designs for use in multimedia applications.

However, this multiprocessor design technique is tough to implement, because it requires the engineer to write twice the code. Further, the designs resulting from such a marriage are limited because two processors cost more, take up more physical space, require more memory, and use up more power than just one would. And so a new kind of processor, the EMP embedded media processor , was born! An embedded media processor combines the best aspects of a traditional microncontroller and a DSP for use in a multimedia product.

As the demand grows for smaller, faster, multifunction, portable embedded products, such as video-enabled cellphones and pda's that play music or games, EMP's become more popular. As a result, an increasing number of engineers need to migrate from using multiprocessor methods to using EMP's in their designs. This book is the one-stop shop for the many engineers who need to understand what embedded media processors can do, and how to implement them.

Covers the significant embedded computingtechnologies—highlighting their applications in wirelesscommunication and computing power An embedded system is a computer system designed for specificcontrol functions within a larger system—often with real-timecomputing constraints.

It is embedded as part of a complete deviceoften including hardware and mechanical parts. Presented in threeparts, Embedded Systems: Hardware, Design, andImplementation provides readers with an immersive introductionto this rapidly growing segment of the computer industry.

Acknowledging the fact that embedded systems control many oftoday's most common devices such as smart phones, PC tablets, aswell as hardware embedded in cars, TVs, and even refrigerators andheating systems, the book starts with a basic introduction toembedded computing systems.

Embedded Systems: Hardware, Design, and Implementation isan ideal book for design engineers looking to optimize and reducethe size and cost of embedded system products and increase theirreliability and performance. Modern electronic systems consist of a fairly heterogeneous set of components. Today, a single system can be constituted by a hardware platform, frequently composed of a mix of analog and digital components, and by several software application layers.

The hardware can include several heterogeneous microprocessors e. Therefore, on the one hand, multi-processor embedded systems are capable of meeting the demand of processing power and flexibility of complex applications. On the other hand, such systems are very complex to design and optimize, so that the design methodology plays a major role in determining the success of the products.

For these reasons, to cope with the increasing system complexity, the approaches typically used today are oriented towards co-design methodologies working at the higher levels of abstraction. Unfortunately, such methodologies are typically customized for the specific application, suffer of a lack of generality and still need a considerable effort when real-size project are envisioned.

Therefore, there is still the need for a general methodology able to support the designer during the high-level steps of a co-design flow, enabling an effective design space exploration before tackling the low-level steps and thus committing to the final technology. This should prevent costly redesign loops. In such a context, the work described in this book, composed of two parts, aims at providing models, methodologies and tools to support each step of the co-design flow of embedded systems implemented by exploiting heterogeneous multi-processor architectures mapped on distributed systems, as well as fully integrated onto a single chip.

The second part focuses mainly on Design Space Exploration, and it presents both some theoretical advancements with respect to the first part, and the development of a prototypal framework that provides practical exploitation of the proposed concepts. Modern signal processing systems require more and more processing capacity as times goes on.

Previously, large increases in speed and power efficiency have come from process technology improvements. However, lately the gain from process improvements have been greatly reduced. Application Specific Integrated Circuits ASICs have long been used to accelerate the processing of tasks that are too computationally heavy for more general processors. The problem with ASICs is that they are costly to develop and verify, and the product life time can be limited with newer standards.

Since they are very specific the applicable domain is very narrow. More general processors are more flexible and can easily adapt to perform the functions of ASIC based designs.

However, the generality comes with a performance cost that renders general designs unusable for some tasks. The question then becomes, how general can a processor be while still being power efficient and fast enough for some particular domain? Application Specific Instruction set Processors ASIPs are processors that target a specific application domain, and can offer enough performance with power efficiency and silicon cost that is comparable to ASICs.

The flexibility allows for the same hardware design to be used over several system designs, and also for multiple functions in the same system, if some functions are not used simultaneously. One problem with ASIPs is that they are more difficult to program than a general purpose processor, given that we want efficient software.

Utilizing all of the features that give an ASIP its performance advantage can be difficult at times, and new tools and methods for programming them are needed. These kinds of algorithms are very common in e.
