At 500kbps CAN, What is the maximum throughput in S32K144 mcu performance?

Question asked by Byungju Kim on Sep 19, 2018

Hi,

 

Throughput was measured in the following environment with 500kbps CAN.

 

MCU: S32K144

Target board: S32K144 EVB and Custom board.

Operation System Clock: 100 MHz

Calculation method: (data bit transmitted for 60 seconds) / 60

Development tools: S32DSforARM,

SDK RTM2.0.0

Tool to use: Vector CANoe

Transfer method:

Boad                                                             CANoe

               <--- request 8byte data ----

             ------- response 8byte data ----->

               <--- request 8byte data ----

              ------- response 8byte data ----->

                                   .

                                   .

                                   .

                       --- Until 60s ---

 

Result: 70kbps.

The throughput is measured to be too low compared to baudrate.

 

Have you ever measured throughput with S32K144 mcu?

Are there tools to measure throughput?

What is the maximum throughput in S32K144 mcu performance?

 

Best regards,

Byungju.
