Diverse experience in working on following Renesas platforms

Renesas Microcontrollers & Microprocessors

RZ Series

RZ/A2M MPUs with DRP Technology

  • The RZ/A2M MPUs features Renesas’ proprietary Dynamically Reconfigurable Processor (DRP) technology for up to 10 times faster image processing

RZ/G Series MPUs

  • RZ/G Series MPUs extends the capabilities of RZ/A MPUs to deliver high-end performance for graphics, multi-stream video and embedded vision

Automotive SoC

R-CAR Series


  • Can be used as the automotive computing platform for the autonomous-driving era


  • R-Car M3 have been optimized so that it can be used for a wide variety of purposes.

Deep platform expertise

  • IMP-X5 is a powerful programmable multicore Digital Signal Processor on V3H/M SOCs
  • PathPartner has the necessary tools and licenses (e2studio) for porting and development of kernels and vision algorithms on IMP-X5
  • IMP-X5’s SIMD capability can be leveraged to optimize the performance intensive vision algorithms
  • IMP-X5’s multiple cores can also be exploited to quickly accelerate an algorithm using multiple threads
  • IMP-X5’s multi-tiered memory architecture and DMA engines can be leveraged to achieve real time performance of time critical algorithms.
R-CAR V3H/M modules : CVe
  • CV engine on the V3H/M processors is a dedicated programmable vision accelerator
  • CV engine is developed on the lines of OpenCL programming of GPUs.
  • PathPartner has extensive knowledge on OpenCL programming, optimizing real time applications such as HEVC decoder on GPU cores using OpenCL
  • The vision application is to be divided in multiple kernels and work items, to be processed concurrently, achieving a high degree of parallelism
  • CV engine is part of the vision acceleration cluster on the V3H/M and is also used by the CNN framework to run certain layers
  • IMP-X5 processing capability can be augmented by CVe by pipelining tasks in parallel
R-CAR V3H/M modules: CNN
  • CNN accelerator on the V3H/M is a powerful framework to speedup the neural network inference workloads
  • Dedicated CNN IP is present on both V3H and V3M, but the one on V3H is more powerful
  • CNN framework also uses IMP-X5 and the CV engine cores to run specific layers which are not supported on the CNN IP hardware
  • The framework also provides support for using custom kernels
  • PathPartner is studying the feasibility of porting the CNN based Traffic Sign Recognition and Pedestrian Detection algorithms on V3M using the framework
  • The network definitions are to be converted to an intermediate format, which is understood by the Renesas components
  • PathPartner has the necessary tools to port the network definitions in prototxt or TensorFlow formats to the Renesas format, with quantization, without loosing accuracy
R-CAR V3H/M modules : IMR
  • The IMR engine on the V3H/M SOCs is a dedicated accelerator for image distortion correction
  • Programmable IMR engine can be used for common Lens Distortion Correction and also to do the pyramid scaling
  • The engine is very useful as a preprocessor block after the ISP and before any vision processing
  • IMR can be used in 3D surround view applications
  • The pyramid scaled images are very useful in object detection algorithms, where template matching techniques are used
