+# RH850/F1K and F1Kx FreeRTOS Port with CC-RH Compiler
+
+## Introduction
+
+This repository contains the port of FreeRTOS for Renesas RH850/F1K and F1Kx microcontrollers using the CC-RH compiler. The following sections provide instructions on how to use this port, a link to the test project, and other relevant information.
+
+## Prerequisites
+- Compiler: CC-RH
+- FreeRTOS version 11.1.0
+
+| Device   | FPU | SMP |
+|----------|-----|-----|
+| F1K      | Yes | No  |
+| F1KM-S1  | Yes | No  |
+| F1KM-S2  | Yes | No  |
+| F1KM-S4  | Yes | No  |
+| F1KH-D8  | Yes | Yes |
+
+## Link to Test Project
+
+The test project can be found [here](https://github.com/FreeRTOS/FreeRTOS-Community-Supported-Demos) (`RH850_F1Kx_CCRH`). This project contains example tasks and configurations to help you get started with FreeRTOS on the RH850/F1K and F1Kx.
+
+## Note
+   1. Configure IPIR Interrupt: Ensure that the bit specifying the destination for binding (requesting) an interrupt is enabled (e.g: IBDxxx register of F1KH-D8) (1)
+   2. `Channel 0` and address `0xFFFEEC00` are used as default configuration for configIPIR_CHANNEL and configEXCLUSIVE_ADDRESS, in case of resource confliction other channel/address can be used. (2)
+   3. The minimal stack size (configMINIMAL_STACK_SIZE) must be included the reserved memory for nested interrupt. This formula can be referred: `(task_context_size) * (1 + configMAX_INT_NESTING) + Stack_depth_of_taskcode`
+   In which, `task_context_size` is calculated as `36*4bytes = 144bytes` (when FPU enabled) or `34*4bytes = 136` (when FPU disabled), configMAX_INT_NESTING is 02 as default.
+   4. `configTIMER_PRESCALE`: This value is required in order to correctly configure clock for `CPUCLK_L`. Refer to Hardware Manual at `Table 44.22` for `option byte`: If the user sets the option byte `CKDIVMD to 1`, then `configTIMER_PRESCALE = 4`. Otherwise, if `CKDIVMD is set to 0`, then `configTIMER_PRESCALE = 2`.
+
+(1)  This is applicable for F1KH-D8 with SMP only.
+
+(2) This is optional and applicable for SMP only.
+
+## Other Relevant Information
+
+- **Documentation:**
+  - Refer to the official [FreeRTOS documentation](https://www.freertos.org/Documentation/RTOS_book.html) for detailed information on configuring and using FreeRTOS.
