# RP2040 W5500 overSSL Coremark Test

> This project compare the performance between dual RP2040 and single RP2040 when transfer data to OpenSSL server.

Original author: Aimee

## Components

- **WIZnet W5500-EVB-Pico** x 1 ([docs](https://docs.wiznet.io/Product/Chip/Ethernet/W5500/w5500-evb-pico))

## Documents and links

This project utilizes the W5500-EVB-Pico board to compare the performance when transmitting data received through SPI communication in Dual Board mode to an OpenSSL server via W5500. Additionally, it compares the performance when transmitting the same amount of data to an OpenSSL server via W5500 in Single Board mode.

**Dual Board coremark Test**
W5500-EVB-Pico(SPI Master) ---> W5500-EVB-Pico(SPI Slave&SSL client) ---> PC(OpenSSL server)
**Single Board coremark Test**
W5500-EVB-Pico(SSL client) ---> PC(OpenSSL server)

#### Test Condition

**Hardware![](https://maker.wiznet.io/upload/ckeditor5/470605436%5F1708960943%2Epng)**
Device : W5500-EVB-Pico
CPU clock : 133MHz
SPI : use DMA/ baudrate 11.0833Mbps

**Software![](https://maker.wiznet.io/upload/ckeditor5/470605436%5F1708960996%2Epng)**
Visual Studio Code : https://code.visualstudio.com/
FreeRTOS Example for RP2040 : <https://github.com/Wiznet/RP2040-HAT-FREERTOS-C>

#### Test Result

![](https://maker.wiznet.io/upload/ckeditor5/470605436%5F1708960861%2Epng)
Coremark score is 81% higher and the time to send data is 43.7% faster.
