Soft processors often use data caches to reduce the gap between processor and main memory speeds. To achieve high efficiency, simple, blocking caches are used. Such caches are not appropriate for processor designs such as runahead and out-of-order execution that require non-blocking caches to tolerate main memory latencies. Conventional nonblocking caches are expensive and slow on FPGAs as they use content-addressable memories (CAMs). This work exploits key properties of runahead execution and demonstrates an FPGA-friendly non-blocking cache design that does not require CAMs.
Computer Architecture: Chapter 4.2 - Pipelined Processor Design presents about Pipelining versus Serial Execution, Pipelined Datapath and Control, Pipeline Hazards, Data Hazards and Forwarding, Load Delay, Hazard Detection, and Stall, Control Hazards, Delayed Branch and Dynamic Branch Prediction.
(BQ) This new emphasis on parallelism is supported by updates reflecting the newest technologies, with examples highlighting the latest processor designs and benchmarking standards. As with previous editions, a MIPS processor is the core used to present the fundamentals of hardware technologies, assembly language, computer arithmetic, pipelining, memory hierarchies and I/O.
There are numerous options for designers in selecting a hardware
platform for custom electronics design, ranging from embedded
processors, Application Specific Integrated Circuits (ASICs),
Programmable Micro-processors (PICs), FPGAs to Programmable
Logic Devices (PLDs). The decision to choose a specific technology
such as an FPGA should depend primarily on the design requirements
rather than a personal preference for one technique over
Many recent texts place instructors in the difficult position of chosing between authoritative, state-of-the art coverage and an approach that is highly supportive of student learning. This carefully developed text was widely praised by reviewers for both its great clarity and its rigor. The book balances theory and practice in depth without getting bogged down in excessive technical or mathematical language and has abundant coverage of current topics of interest, such as programmable devices, computer-aided design, and testability.
For example, a few years ago, I was the Development Tools Marketing Manager for a semiconductor manufacturer. I was speaking with the Software Development Tools Manager at our major account. My job was to help convince the customer
that they should be using our RISC processor in their laser printers. Since I owned the tool chain issues, I had to address his specific issues before we could convince him that we had the appropriate support for his design team.
If we look at a problem as a whole, it may seem
impossible to solve because it is so complex.
o writing a tax computation program
o writing a word processor
• Complex problems can be solved using top-down
design, also known as stepwise refinement,
o We break the problem into parts
o Then break the parts into parts
o Soon, each of the parts will be easy to do
Modern embedded systems come with contradictory design constraints. On one hand, these systems often target mass production and battery-based devices, and therefore should be cheap and power efficient. On the other hand, they still need to show high (sometimes real-time) performance, and often support multiple applications and standards which requires high programmability.
Complete the conversation between a web designer and his client by choosing from the dropdown menu.
Web designer (WD): So (1) I ask what kind of (2) you want? Client (C): Well, I’m a singer in a band, and I (3) an online presence to help with promotion, that kind of thing. I don’t want anything too complicated. It’d be good if it looked nice, though. Perhaps a nice (4) and some attractive (5) . WD: OK, that doesn’t sound too complicated. Will you need (6) and (7) , too? I mean, do you want people to be able to listen to...
In this paper, the five-band notch filter was designed using MATLAB and implemented by the floating-point digital signal processor TMS320C6711 based on TI's DSP starter kit (DSK) board connected to the parallel port of the PC through the DB25 cable included with the DSK package. The original segment of symphony orchestra corrupted two undesired sinusoids at frequencies of 750Hz and 1750Hz is conduced to input of DSK to produce the corrupted input signal which is saved in the wave file (Corrupthandel.wav) for the digital signal processor. ...
We discuss ways of allowing the users of a natural language processor to define, examine, and modify the definitions of any domain-specific words or phrases known to the system. An implementation of this work forms a critical portion of the knowledge acquisition component of our Transportable English-Language Interface (TELl), which answers English questions about tabular (first normal-form) data files and runs on a Symbolics Lisp Machine.
Chapter 13 - Database design for student loan limited. This chapter presents a case derived from discussions with information systems professionals of a large commercial processor of student loans. Servicing student loans is a rather complex business owing to the many different kinds of loans, changing government regulations, and numerous billing conditions.
Chapter 1 "Computer system overview". After studying this chapter, you should be able to: Describe the basic elements of a computer system and their interrelationship, eplain the steps taken by a processor to execute an instruction, understand the concept of interrupts and how and why a processor uses interrupts,...
Chapter 9 - Uniprocessor scheduling. This chapter begins with an examination of the three types of processor scheduling, showing how they are related. We see that long-term scheduling and mediumterm scheduling are driven primarily by performance concerns related to the degree of multiprogramming.
Chapter 14 - Computer security threats. After studying this chapter, you should be able to: Describe the various approaches to virtualization, understand the processor issues involved in implementing a virtual machine, understand the memory management issues involved in implementing a virtual machine, understand the I/O management issues involved in implementing a virtual machine,...

(BQ) The book uses a MIPS processor core to present the fundamentals of hardware technologies, assembly language, computer arithmetic, pipelining, memory hierarchies and I/O.Because an understanding of modern hardware is essential to achieving good performance and energy efficiency, this edition adds a new concrete example, Going Faster, used throughout the text to demonstrate extremely effective optimization techniques.
The .NET platform is the foundation upon which the next generation of software
will be built. Microsoft has invested a lot of capital in its development, and
is putting its considerable weight behind its adoption as a new standard. A long
list of Microsoft partners have also announced support for .NET tools and components—
you can check http://msdn.microsoft.com/vstudio/partners for a current
list of vendors who have .NET offerings.
The .NET platform is much more than a new language, software development
kit (SDK), or even an operating system.
Microcontroller is a computer that is integrated on a chip, it is often used to control electronic devices.
