Architecture Functonal Design

• Formalize the process by which signal processing architects assess the processing complexity required to implement the system functional algorithm
  • Formalize the criteria to select an architecture
  • Translate processing flows to architecture independent DFGs
  • Identify reusable library primitives
  • Begin generation of new primitives
  • Algorithm implementation analysis, simulation, and optimization
  • Identify modes of operation and mode transitions

• Architecture/Hardware
  • Performance: Peak and sustained
  • I/O bandwidth: Intra-board, board-to-board, chassis-to-chassis, pin requirements
  • Memory (size/performance): Cache, local and global
  • Power dissipation: Static and dynamic
  • Testability: Fault coverage, BIST support, test time
  • Mechanical packaging complexity
  • Thermal issues
  • Scalability/upgradability

• Software
  • Compliers: Availability/efficiency
  • Operating system: Functionality, performance, availability, maturity, board support package
  • Costs: Non-recurring, production, test, life-cycle
  • Risks: Technical, schedule, cost
  • Quality: Defect level, reliability
