CMSIS 合规

IAR Embedded Workbench is compliant with Arm Cortex Microcontroller Software Interface Standard (CMSIS).

What is CMSIS?

The Arm Cortex Microcontroller Software Interface Standard (CMSIS) provides a single, scalable interface standard across all Cortex-M series processor vendors which enables easier code re-use and sharing across software projects to reduce time-to-market for new embedded applications.

The CMSIS has been developed by Arm in close partnership with several key silicon and software vendors including Atmel, IAR Systems, Micrium, NXP, SEGGER, STMicroelectronics and Texas Instruments, and provides a common approach to interface to peripherals, real-time operating systems, and middleware components.

The standard has been designed to be fully scalable to ensure that it is suitable for all Cortex-M processor series microcontrollers from the smallest 8KB device up to devices with sophisticated communication peripherals such as Ethernet or USB-OTG. (The CMSIS memory requirement for the Core Peripheral Access Layer is less than 1KB code, less than 10 bytes RAM.)

Arm provides as part of the CMSIS the following software layers that are available for various compiler implementations:

  • Core Peripheral Access Layer: contains name definitions, address definitions and helper functions to access core registers and peripherals. It defines also an device independent interface for RTOS Kernels that includes debug channel definitions.
  • Middleware Access Layer: provides common methods to access peripherals for the software industry. The Middleware Access Layer is adapted by the Silicon Vendor for the device specific peripherals used by middleware components.

These software layers are expanded by Silicon partners with:

  • Device Peripheral Access Layer: provides definitions for all device peripherals
  • Access Functions for Peripherals (optional): provides additional helper functions for peripherals

CMSIS-DAP

CMSIS-DAP is the interface firmware for a debug probe that translates USB packets to the Arm core SWD or JTAG protocol. This allows the C-SPY Debugger, with the addition of just a USB cable, to connect to any development board implementing the CMSIS-DAP connection.

CMSIS-NN

CMSIS version 5.3 adds the CMSIS-NN software library, a collection of efficient neural network kernels developed to maximize the performance and minimize the memory footprint of neural networks on Cortex-M processor cores.

 

语言和标准

IAR C/C++ 编译器提供 C 和 C++ 编程语言的不同方言，以及针对嵌入式编程的不同扩展（请注意，并非所有语言标准都支持所有目标实现）。编译器可以被指示禁用扩展，以严格遵守标准。

支持多种行业标准的调试和映像格式，与大多数流行的调试器和模拟器兼容。其中包括 ELF/DWARF（如适用）。

符合 ISO/ANSI C/C++ 标准

IAR C/C++ 编译器遵守以下 C 语言编程标准的独立实现：

  • INCITS/ISO/IEC 9899:2018，即 C18（仅限最新版本）

  • 编译器支持所有 C++17 功能。C++ 库支持 C++14，没有补充 C++17（仅限最新版本）

  • ISO/IEC 14882:2015，即 C++14

  • INCITS/ISO/IEC 9899:2012，即 C11

  • ANSI X3.159-1989，即 C89

不同编译器的 ISO/ANSI C/C++ 兼容性水平存在差异。如需了解完整信息，请参考您所选产品中的 IAR C/C++ 编译器用户文档。

IEEE 754 标准

IAR Embedded Workbench 支持 IEEE 754 标准的浮点运算。

MISRA C

MISRA C 是由 MISRA（汽车工业软件可靠性协会）制定的 C 编程语言的软件开发标准。它的目的是促进嵌入式系统中的代码安全、可移植性和可靠性，特别是那些用 ISO C 语言编程的系统。

MISRA C 标准的第一版是《汽车软件中 C 语言的使用指南》，诞生于 1998 年。2004 年该协会发布了第二版指南，其中进行了许多重大修改，包括对规则进行了全面的重新编号。此外，MISRA C:2012 的扩展支持和 MISRA C++:2008 用于识别 C++ 标准中的不安全代码结构也被添加到标准中。

IAR Embedded Workbench 包含一个插件产品 C-STAT，因此您可以检查应用是否符合 MISRA C:2004、MISRA C++:2008 和 MISRA C:2012 定义的规则。

测试验证

我们使用以下商业测试套件来测试我们的工具是否符合标准：

  • 适于 ISO/IEC C 标准一致性的 Plum Hall 验证测试套件

  • 适于测试 C++ 标准一致性的 Perennial EC++ 验证套件

  • Dinkum C++ Proofer 测试我们的库是否符合 C 和 C++ 标准，并根据 C++ 标准测试我们的 STL 实现

除商业套件外，我们还使用一些内部测试套件来测试新功能、执行回归测试、纠正错误等。
