Avalon Interface Specification,The Avalon interface specification is designed to accommodate peripheral development for the system-on-a-programmable-chip (SOPC) environment. The specification provides peripheral designers with a basis for describing the address-based read/write interface found on master and slave peripherals, such as microprocessors, memory, UART, timer, etc.

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa.
For example,
>> project.name = MyProject
>> project.id = 1234
>> project.param.a = 3.1415
>> project.param.b = 42
becomes with str=xml_format(project, off )
"<project>
<name>MyProject</name>
<id>1234</id>
<param>
<a>3.1415</a>
<b>42</b>
</param>
</project>"
On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).

In this paper, we describe the development of a rapidly reconfigurable system in which the users’ tacit knowledge and requirements are
elicited via a process of Interactive Evolution, finding the image processing parameters to achieve the required goals without any need for
specialised knowledge of the machine vision system. We show that the resulting segmentation can be quickly and easily evolved from
scratch, and achieves detection rates comparable to those of a hand-tuned system on a hot-rolled steel defect recognition problem.

The TAS3204 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable, 48-bit digital audio processor, a 3:1 stereo analog input MUX, four ADCs, four DACs, and other analog functionality. The TAS3204 is programmable with the graphical PurePath Studio? suite of DSP code development software. PurePath Studio is a highly intuitive, drag-and-drop environment that minimizes software development effort while allowing the end user to utilize the power and flexibility of the TAS3204’s digital audio processing core.
TAS3204 processing capability includes speaker equalization and crossover, volume/bass/treble control, signal mixing/MUXing/splitting, delay compensation, dynamic range compression, and many other basic audio functions. Audio functions such as matrix decoding, stereo widening, surround sound virtualization and psychoacoustic bass boost are also available with either third-party or TI royalty-free algorithms.
The TAS3204 contains a custom-designed, fully-programmable 135-MHz, 48-bit digital audio processor. A 76-bit accumulator ensures that the high precision necessary for quality digital audio is maintained during arithmetic operations.
Four differential 102 dB DNR ADCs and four differential 105 dB DNR DACs ensure that high quality audio is maintained through the whole signal chain as well as increasing robustness against noise sources such as TDMA interference.
The TAS3204 is composed of eight functional blocks:
Clocking System
Digital Audio Interface
Analog Audio Interface
Power supply
Clocks, digital PLL
I2C control interface
8051 MCUcontroller
Audio DSP – digital audio processing

數字化電源的特點：1.控制智能化它是以數字信號處理器(DSP)或微控制器(MCU)為核心，將數字電源驅動器及PWM控制器作為控制對象而構成的智能化開關電源系統。傳統的由微控制器控制的開關電源，一般只是控制電源的啟動和關斷，并非真正意義的數字電源。2.數模組件組合優化采用“整合數字電源”(Fusion Digital Power)技術，實現了開關電源中模擬組件與數字組件的優化組合。例如，功率級所用的模擬組件MOSFET驅動器，可以很方便地與數字電源控制器相連并實現各種保護及偏置電源管理，而PWM控制器也屬于數控模擬芯片。3.集成度高實現了電源系統單片集成化(Power System on Chip)，將大量的分立式元器件整合到一個芯片或一組芯片中。4.控制精度高能充分發揮數字信號處理器及微控制器的優勢，使所設計的數字電源達到高技術指標。例如，其脈寬調制(PWM)分辨力可達150ps(10~12s)的水平，這是傳統開關電源所望塵莫及的。數字電源還能實現多相位控制、非線性控制、負載均流以及故障預測等功能，為研制綠色節能型開關電源提供了便利條件。5.模塊化程度高數字電源模塊化程度高，各模塊之間可以方便地實現有機融合，便于構成分布式數字電源系統，提高電源系統的可靠性。
