MCUSW
CDD IPC Profiling Application

Introduction

This application measures the CPU cycles required for transmission, reception of N number of bytes to, from a given core. As an example communication between MCU 1 0 and MCU 2 1 will be considered (or other cores). Similar approach would be employed for other cores. Please refer (Supported Drivers) for details on core that can host MCAL

Simulates transmission and reception of messages of different length, including standard lengths of 8 bytes and 64 bytes.

SoC Host Core Remote Cores Comments
J721E MCU 1 0 MCU 2 1 MCAL could be hosted on other cores but this demo application runs only on MCU 1 0, at this point of time

Dependencies

Local Application

This application depends on multiple components and are detailed in sections below

  1. FREERTOS: Uses Task, semaphore, Interrupt Handling HWI and Profiling Utility.
  2. MCAL
    • Cdd Ipc Driver
  3. MCAL BSW Stubs Stubs at (SDK Install Directory)/mcusw/mcuss_demos/Bsw_Stubs are used.
  4. MCAL Configurations Cdd Ipc Configurations at (SDK Install Directory)/mcusw/mcuss_demos/mcal_config are used.
  5. The MCAL based profiling application is hosted on MCU 1 0 (could also be hosted on other cores in future, (Supported Drivers))

Remote Application

This application depends on multiple components and are detailed in sections below

  1. FREERTOS: Uses Task, semaphore, Interrupt Handling HWI and Swi.
  2. PDK
    • IPC Driver

Flow Chart

The flow chart below depicts the profiling application

  • ipc_remote_app_(BUILD_OS_TYPE)_mcu2_1_release.xa53fg would be hosted on Remote Core (MCU 2 1)
  • cdd_ipc_profile_app__(BUILD_OS_TYPE)_mcu1_0_release.xer5f would be hosted on Local Core (MCU 1 0)

Note: Both applications need to be used with same OS.

Test Setup / Configurations used

EVM

  1. Require the EVM only, as the IPC relies on built-in mailbox hardware.
