ABSTRACT
In this paper we describe the design and implementation
of a flexible, and extensible, just-in-time ARM simulato
designed to run co-operatively with a multi-core DSP sim
ulator on x86 hosts. The integrated simulator can boo
ARM/Linux alongside another operating system running on
DSP cores, thus truly supporting a heterogeneous multi-core
operating environment. In addition, the simulator facili
tates exploration of several system design parameters such
as memory latencies, cache organization etc. via lightweigh
user-defined instrumentation.
We provide performance results and highlight the impac
of design choices on our overall performance and design ob
jectives. We also discuss implementation techniques and
trade-offs between the competing requirements of simula
tion speed versus accuracy in a complex multi-core simula
tion environment.
