Abstract
The design of MultiProcessor Systems-on-Chip
(MPSoC) emphasizes intellectual-property (IP)-based
communication-centric approaches. Therefore, for the optimization
of the MPSoC interconnect, the designer must develop
traffic models that realistically capture the application behavior
as executing on the IP core. In this paper, we introduce a
Reactive IP Emulator (RIPE) that enables an effective emulation
of the IP-core behavior in multiple environments, including bitand
cycle-true simulation. The RIPE is built as a multithreaded
abstract instruction-set processor, and it can generate reactive
traffic patterns. We compare the RIPE models with cycle-true
functional simulation of complex application behavior (tasksynchronization,
multitasking, and input/output operations).
Our results demonstrate high-accuracy and significant speedups.
Furthermore, via a case study, we show the potential use of the
RIPE in a design-space-exploration context
