PERFORMANCE ANALYSIS TUNING TOOL
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.
The following performance analysis tuning tool is supported by the V850 Series.
Features
Easy-to-use interface
Profiling function
Performance estimation
Analysis result output function
Performance tuning function
The wizard-type GUI allows easy specification of conditions. Moreover, profiling, performance analy-
sis, and tuning are automatically performed.
Two 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 analysis changing the internal ROM size, instruction cache size, etc. is possible, and the
analysis results can also be used for microcontroller selection.
The following analysis results are output.
· Interfunction call relations, call count information
· Function execution time information
· Cache miss-hit information
The following types of tuning can be performed.
· Instruction cache optimization
· High-speed access memory allocation optimization
(Optimum placement of functions so as to reduce cache miss-hits)
(Allocation of functions that constitute bottlenecks to high-speed access memory such as internal
ROM)
