Configuratie-geheugen




                        3
Gebruik van herconfiguratie
• Vandaag: configuratie op grote tijdschaal
   – System update
   – Bug fix
   – ...
• Wij: configuratie op kleine tijdschaal
   – Run-time herconfiguratie
   – Doel:
      • Sneller
      • Kleiner
   – Probleem:
      • Genereren van een configuratie is verschrikkelijk traag


                                                                  4
Parameteriseerbare Configuraties
• Parameterizable configuration:
  – Vector: een element per configuratie-bit
  – Element: Boolese functie (tuning functions)
  – Tuning functions is functie van een verzameling
    parameters
• Regular configuration:
  – A vector of 1’s and 0’s
            A                           1
            0                           0
           A+B                          1
                        A=1 B=0
           A*B                          0             5

Herconfiguratie-bewuste routeerder
            voor FPGA's
• CAD-thesis
• TRoute
  – Uitdenken timing-model
  – Uitbreiden naar andere
    architecturen
• Praktisch:
  – Java




                                      7
SNORT netwerkintrusiepreventie op
              FPGA
• Ontwerpsthesis
• Pakketen vergelijken met Reguliere expressies
• Parametriseerbaar ontwerp (onderzoek):
  Reguliere expressie is de parameter
• Praktisch:
  – FPGA-tools
  – VHDL
  –C


                                                  8
Adaptieve stochastische neuronen
• Ontwerpsthesis
• Egalisatie draadloos communicatiekanaal
  Adaptieve filtering met neuraal netwerk
• Parametriseerbaar ontwerp:
  Filtercoëfficiënten zijn de parameters
• Praktisch:
  – FPGA-tools
  – Matlab
  – VHDL
  –C
                                            9
Dynamische herconfiguratie zorgt voor
goedkopere Océ hogesnelheidsscanner
• Ontwerpsthesis
• Module gebaseerde herconfiguratie en
  beeldverwerking
• Met OCE (Nederland)
• Praktisch:
  – FPGA-tools
  – VHDL
  –C

                                         10
Bouw je eigen processor
•   Ontwerpsthesis
•   Uitbreiden van de OpenSPARC architectuur
•   Onderzoeken van invloed op de prestatie
•   Samen met Sean Rul
•   Praktisch:
    – FPGA-tools
    – Verilog
    –C


                                               11
