ABSTRACT
Software simulation of one computer on another tends to be slow. Traditional simulators typically execute about 100 instructions on the host machine per instruction simulated. Newer simulators reduce the expansion factor to about 10, by saving and reusing translations of individual instructions. This paper describes an experimental simulator which takes the progression one step further, translating groups of instructions as a unit. This approach, combined with flow analysis, reduces the expansion factor to about 4. The new simulator simulates System/370 on a RISC, namely the IBM RT PC.

An ultra-fast instruction set simulator
In this paper, we present new techniques which further improve the static compilation-based instruction set architecture (ISA) simulation by the aggressive utilization of the host machine resources. Such utilization is achieved by defining a low-level ...
Dynamic Profile of Instruction Sequences for the IBM System/370
Instruction mixes such as the Gibson mix have been used for a long time as workload models for CPU's. However, since an instruction mix does not indicate the order of instruction execution, it is not suitable for the performance evaluation of advanced ...
