SARA - Scaleable Architecture for Realtime Applications - llh@idt.mdh.se
The research question is: will it be possible to meet the following objectives if software functions and new functions implements in hardware? Scaleable and Simpler Flexible Observable and Controllable Efficiency and higher Performance Better Low-Cost/Real-time Performance Value, Fault Tolerance, SARA next generation-Scaleable Architecture for Real-time Applications-
We work only with MIMD architecture We work also with Power PC, VME, PCI bus ....
Scalability and Simple RAM RAM RAM RAM CPU0 CPU1 CPU2 CPUA GRAM RTUA More performance - no change in software - more processors RAM RAM RAM CPU0 CPU1 CPU2 Next sub system RTUB
Flexibility Different software architectures could use the same hardware architecture. New version - no change in hardware - flexible hardware
Problem: Verifikation!Hur får vi styrbar/öppnare system?Gäller också en processor system
Observable and controllable, Shared Pool of Computer Resources... Important, Important... the key to faster verification and better analyse of RT-system
Observable and controllableRoad Map for ASIC Design # gates pro week ASIC ? Verification Design 1990 1995 2000
Low Hardware and Software Overhead (simplifications), state-of-the-art high performance commercial standard microprocessors, buses etc. Hardware faster then software Efficiency and Higher Performance
ASIC designs Standard Components, IP etc. Standard Software and debuggers System on Chip ...... Cost/realtime performance,
Better Task Memory Manager Better Watchdog functions Better Scheduling algoritms etc. Fault tolerance,
