Illinois Verilog Model version 1.0

The Illinois Verilog Model (IVM) is a Verilog implementation of an Alpha microprocessor. The microarchitecture is a superscalar, dynamically scheduled pipeline, executing a subset of the Alpha instruction set. The processor includes such features as speculative instruction scheduling, memory dependence prediction, and sophosticated branch prediction. Up to 132 instructions can be in-flight in the 12-stage pipeline. Not including the caches and predictor tables, the processor core consists of approximately 50,000 bit elements of state (pipeline latches and RAM storage).
