Introduction Framework de publication Web Interaction avec de nombreuses sources de donnees (systemes de fichier, bases de donnees relationnelles, LDAP, bases de donnees XML, etc.) Generation a partir de documents XML via le declenchement d'evenements SAX, des contenus sous des formats varies (HTML, WML, PDF, SVG,RTF). Le langage XSP XSP : eXtensible Server Page XSP est un document XML avec du code java imbrique Le document XSP est compile et execute avant de retourner le resultat Ce qui donne un document XML intermediaire dans lequel les instructions java ont ete remplacees par leur resultat,au format XML. SITEMAP.XMAP Annuaire des applications web Les sitemap Cocoon peuvent servir a plusieurs choses, en particulier la definition de composantes et une partie de la logique applicative.

SITEMAP.XMAP suite Il est possible de referencer une application web autrement que par le sitemap principal. Composant Cocoon A l'heure actuelle, plus de 70 a 80 composants sont presents dans la version cocoon 2.1.

MIPS Instruction Set See Appendix C in the textbook for a detailed description of every instruction.
Pseudocode Using Pseudocode to Document a MIPS Assembly Language Program When documenting an algorithm in a language such as Pascal or C, programmers use descriptive variable names such as: speed, volume, size, count, amount, etc.
As an assembly language programmer you must take maximum advantage of the processor registers. We use register names in pseudocode because the purpose of the pseudocode is to document an assembly language program. Pseudocode for assembly language programs will have the appearance of Pascal or C in terms of control structures and arithmetic expressions, but descriptive variable names will usually only appear in the LOAD ADDRESS (la) instruction where there is a reference to a symbolic memory address. Now for an example, let us suppose that we want to write an assembly language program to find the sum of the integers from 1 to N.
Translation of a “While” statement Here is a translation of the above “while” pseudocode into MIPS assembly language code. 0; \$t0 = \$t0 -1) do {\$a0 = \$a0 + \$t0} The following is a translation of the above “for-loop” pseudocode to MIPS assembly language code. PLAN Presentation Historique Introduction Installation Les interets de cocoon Fonctionnement de Cocoon Base de donnee. Ce document XML intermediaire est soumis a nouveau a un processus de Transformation,avec un programme XSLT, afin que le resultat produit(HTML,WML,PDF…)soit transmis au programme client. Les sitemap servent a determiner, en fonction de l'URL d'appel, quel producteur, quel transformateur et quel serialiseur utiliser. File[Rd] = Rs operation Rt A Register Transfer Description of the Control Logic IR = Mem[PC] PC = PC + 4 Decode Instruction Read from Reg.

For example, you may have a value in register \$s0 corresponding to speed, a value in register \$s1 corresponding to volume, a value in register \$s2 corresponding to size, and a value in register \$t3 corresponding to count.
Unless you identify the registers being used, the pseudocode is quite limited in terms of having any correspondence to the assembly language code. CPU takes each instruction and executes it, possibly storing new data values as the program executes. File lw or sw Memory[Address] = Rt sw lw R-Type If (Rs == 0 ) then PC = PC + Offset beqz Address = Rs + Offset Reg. To efficiently execute code, a compiler will attempt to keep the variables that are referenced most often in processor registers because access to a variable in a processor register is much faster than access to memory. When using pseudocode to document an assembly language program, you will be expected to use the names of the registers you intend to use in the assembly language code. You will also find that as soon as you are able to develop the pseudocode in this format it is a very simple process to translate pseudocode into assembly language code. On the next slide you will see a pseudocode description of the algorithm and following that the corresponding assembly language program, where processor register \$t0 is used to accumulate the sum, and processor register \$v0 is used as a loop counter. Special languages allow people to communicate with computers since they are not capable of understanding human languages. End your message with a colon followed by a space and leave the cursor positioned after the space. It is advisable to create a cross reference table between the processor register name and what it is being used for in the program.
When writing pseudocode you should specify the processor registers you are planning to use to accomplish the task. The names used to reference these registers are defined in Figure 2.1 on page 4 in the textbook. 1.7If a 500 MHz machine takes one-clock cycle to fetch and execute an instruction, then what is the instruction execution rate of the machine?
1.9Let’s suppose we have a 40-year-old computer that has an instruction execution rate of one thousand instructions per second. How long would it take in days, hours, and minutes, to execute the same number of instructions that you derived for the 500 MHz machine?
