As mentioned before, the main topic of this study is to evaluate and validate the
effect of the Xilinx MicroBlaze features and the proposed hardware/software par-
titioning approach on the embedded system performances.
6.1 Experimental Setup
6.1.1 Hardware Experimental Setup
Performance evaluation was estimated on a
first time by a basic measurement of the
different MicroBlazesoft-core con
gurations implemented on Xilinx Virtex-5
development board (XUPV5-LX110T, xc5vlx110t, grade ff1136, speed-1), illus-
trated in Figure

Processor performance can be measured in different metrics such as execution
time, energy consumption and area utilization. The most common metric is the time
required for a processor to accomplish the de
ned task. In some architecture using
an internal CPU clock driver, execution time presents the clock driver multiplied by
the total instruction cycle count. In our case, execution time is measured using a
Logic Analyser to have a high-precision measurement.
