PERFORMANCE ANALYSIS TUNING TOOL

Features

◆ Easy-to-use interface

The wizard-type GUI allows easy specification of conditions. Moreover, profiling, performance analy-

sis, and tuning are automatically performed.

◆ Profiling function

Tw o profiling approaches are available, one in which trace data is analyzed during execution using the

in-circuit emulator trace function, and another in which software analysis is performed by inserting

probe code into the target program.

◆ Performance estimation

Performance analysis changing the internal ROM size, instruction cache size, etc. is possible, and the

analysis results can also be used for microcontroller selection.

◆ Analysis result output function

The following analysis results are output.

· Interfunction call relations, call count information

· Function execution time information

· Cache miss-hit information

◆ Performance tuning function

The following types of tuning can be performed.

· Instruction cache optimization

(Optimum placement of functions so as to reduce cache miss-hits)

· High-speed access memory allocation optimization

(Allocation of functions that constitute bottlenecks to high-speed access memory such as internal

ROM)

The following performance analysis tuning tool is supported by the V850 Series.

TW850: Tuning tool for V850 Series

The TW850 performance analysis tuning tool is a tuning tool for embedded software.

It enables performance estimation, performance prediction, and performance improvement through easy operation.

The TW850 tool can also be used for the V850E with on-chip cache and other system LSI devices.
