Performance Analysis
The TA660 provides continuous Real-Time performance analysis that
operates with Pre-defined or User-defined analysis files. On-board
dual ported FIFOs interface between the counters and the host system
for transferring the measured data in real-time without ever having to
stop the counters. This feature provides a very complete and accurate
event count of up to 533 MB/Sec. An implementation of twelve
counters with up to 32 bits allows a virtually unlimited count of
events.
TA660A includes 12 counters, 8 of which may be programmed to
monitor the primary bus activities and the other 4 may used for
connection to point-to-point signals or the secondary bus.
Your TA660 includes complete setups to measure the most typical
parameters as well as giving you the ability to create your own setup.
Real time Performance Analysis allows you to count actual data
transfers for any agent or agents matching user specified address,
measure and report bus utilization efficiencies, throughput, latencies
and retries, on-the-fly.
You may use real time Performance Analysis simultaneously with the
exerciser to generate traffic on the bus and measure performance of
the target.
Performance Analysis results are presented in a Twelve-color display
that you may customize with your own color preferences and may be
recorded in graphical format for later review or demonstration.
Measurement intervals are selectable from 500 µsec to 10 minutes.
Statistical Analysis
Statistical Analysis is implemented by capturing data in memory and
then performing software post processing.
Statistical Analysis measures and reports on Min, Max and Average
occurrences for several different parameters such as Latencies, Retry,
Data Transfers, Command Utilization, Bus Utilization and various
Target Terminations.
The PCI Analyzer (Allowing the Master card to be plugged into
the expansion slot on top) can also measure latencies from request
to the 1
st
data transfer including all of the retries in between.
The data capture & trigger for post processing may be initiated per
user defined events on the bus, therefore yielding a very repetitive and
consistent result.
