Evaluation of a low overhead predication system for a deterministic VLIW architecture targeting real-time applications
چکیده انگلیسی
Recently, there is a considerable research effort on providing time-predictable architectures for real-time systems. The correct functioning of them depends not only on the logically correct response, but also the time when it is given. To provide such determinism, the use of VLIW (Very Long Instruction Word) architecture with in-order pipelines and predication support became attractive. Predication is an architecture technique which helps the compiler to translate control dependencies into data dependencies reducing control flow overhead and enhancing the worst-case timing analysis. Since hardware predication support does not come for free, the goal of this work is to investigate a low overhead predication system for multi-issue VLIW machines targeting real-time applications. This study was conducted using a VLIW 4-issue prototype based on the VLIW HP ST231 ISA describing the hardware implementation and the benefits on the worst-case performance.
