Catalyst Enterprises, Inc. TA700/800 Overview
12
TA700/800 includes 8 counters which may be programmed to monitor the primary bus
activities and point-to-point signals or signals from the secondary bus.
Your TA700/800 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 record 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 1st 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.
The parameters measured may be selected for graphical display on the screen and may
be saved as graphical or list files for later review.
In the exerciser mode the TA700/800 can initiate data transfer to a target while the
trace statistics measures the latency response of the target.
Special Capabilities
Several other features are included in the TA700/800 such as Protocol Errors,
Mnemonics, Device Compliance Testing. Please refer to the appropriate sections for
each of these features.
