RH850 Family for Automotive
The RH850 is Renesas Electronics' latest automotive microcontroller family that offers high performance balanced with very low power consumption over a wide and scalable range of products. This family offers the rich functional safety and embedded security features needed for new and advanced automotive applications.
iSYSTEM provides comprehensive debug and trace support for the entire Renesas RH850 Controller Family. The iSYSTEM BlueBox On-Chip-Analyzers connect via any available debug and trace interface of this family (see below). Complex AUTOSAR applications can be analyzed and optimized to ensure that timing constraints are fulfilled.

RH850-specific Debug/Trace Features
RH850 Software Trace
About RH850 Software Trace: Software Trace is a RH850-specific trace solution based on Code Instrumentation. Software Trace messages are generated when the CPU executes dedicated instructions, DBCP, DBTAG and DBPUSH. The Software Trace messages can either be stored in an on-chip trace RAM (if available) or can be streamed out via the LPD-4 interface, operating in Software Trace streaming mode.
Timing & Performance Measurement Unit (TPU)
Features:
- On-chip Counter Structure to measure Time (Clock Cycles) and Performance Metrices
- Can be controlled (start/stop) by means of Trigger Event Unit (TEU)
- Counter increment by Stop Events or Debug Clock (JTAG / LPD Clock)
- Optional CPU Break on Counter Threshold and/or Overflow
- Two Sub-Units: Time Measurement & Performance Measurement
Sample TPU Measurement:
Measure Runtime of Function "EE_RUN_Runnable_R1"
- Number of Calls
- Min/Max Execution Time per Call
- Accumulated Execution Time (to calculate average Execution Time)
| Unit 0: | Unit 1: | Unit 2: | Unit 3: |
| Accumulated Execution Time | Minimum Execution Time | Maximum Execution Time | Number of Function Calls |
ADIO & CAN Trace
A trace recording via the Nexus port allows a time correlation with Analog/Digital or CAN/LIN bus signals captured by means of the ADIO and/or CAN/LIN Add-On Module of the iC5700.
Figure 8 shows a correlated Nexus Trace and CAN bus recording. The trace was recorded on a Sensor Fusion demonstrator platform, based on RH850/F1H, created within a cooperation project between the companies INCHRON, OpenSynergy and iSYSTEM. The profiler timeline shows a combined trace of CAN bus, program flow, microCOQOS Hypervisor virtual machines and multiple AUTOSAR OS Tasks.
