Summary of ARM development tools

ARM software development tools according to different functions, respectively, build the software, compiling the software, link software, debugging software, embedded real time operating system, libraries, evaluation board, JTAG emulator, online simulators, at present, around the world more than forty companies offer different types of products.
Users to choose an embedded ARM processor development system, choose the right development tools can speed up development, and save development costs. So a set containing the editing software, compiler software, compilation of software, links, software, debugging software, project management and integrated development environment libraries (IDE) in general is essential, as embedded real-time operating system, evaluation boards, etc. Other application development tools you can use the software size and development plans.
Use integrated development environment to develop ARM-based applications, including editing, compile, assemble, link, etc. all in the PC, to complete, and commissioning work is required in conjunction with other modules or products to be completed, the current testing method has the following common categories:
1, the instruction set simulator
Part of the integrated development environment provides the instruction set simulator, can be easily done on the user PC, part of the commissioning of a simple, but due to instruction set simulator and real hardware environment very different, so even if the user instruction set simulator debugging by using the procedures may not be in a real hardware environment to run, users will eventually have to complete the entire hardware platform application development.
2, the presence of monitoring software
Presence of monitoring software (Resident Monitors) is a program running on the target board, integrated debugging software development environment through an Ethernet port, parallel port, serial ports and other communication port to interact with the presence of monitoring software, the debugging issued an order notification software control program resides on the implementation of monitoring software, read and write memory, read and write registers, set breakpoints and so on.
Presence of monitoring software is a relatively cheap and effective way of debugging, do not need any other hardware debugging and simulation equipment. ARM's Angel is the type of software, most embedded real-time operating system is the use of such software debugging, the difference is in the embedded real-time operating system, the presence of monitoring software is a task as the operating system exists.
Presence of monitoring software is its inconvenience hardware requirements are relatively high, generally carried out only after the hardware stable development of application software, and it takes some of the resources on the target and can not run at full speed on the program full simulation Therefore, some critical situation is not very suitable.
3, JTAG Emulator
JTAG emulator, also known as JTAG debugger, through the ARM chip JTAG boundary scan debug port equipment. JTAG emulator cheaper, more convenient connections through the existing JTAG boundary scan port and the ARM CPU core communication, is completely non-intrusive (ie, not using on-chip resources) debugging, it does not require the target memory, do not take up any port of the target system , which is required for resident monitoring software. In addition, the JTAG debug the target program is the implementation on the target board, the simulation closer to the target hardware, so a lot of interface issues, such as high-frequency limits of operation, AC and DC parameters do not match, wire length restrictions are minimized . Use integrated development environment with JTAG emulator for development is the most widely used debug mode.
4-Circuit Emulator
Online Simulation uses simulation completely replace the target board header CPU, you can complete simulation of the behavior of ARM chip, providing more in-depth debugging. However, such simulators to be able to clock faster than 100MHz full simulation of the processor, usually have to use extremely complex design and technology, so its price is more expensive. Line is usually used in the ARM emulator hardware development, software development in the less used, and their high cost is also difficult to popular online emulator factors.
In the following sections, we selected the ARM SDT, ARM ADS, MULTI 2000, Hitools for ARM, Embest IDE for ARM five integrated development environment for the reader a brief introduction, these products are relatively smooth in domestic sales channels user can easily buy.
