1 EECS 373 Design of Microprocessor-Based Systems Ryan Heise, Matthew Linder, David Reddmann Special Topics: Software Toolchains

A set of software products where the output of one product is used as the input for another Software Development Toolchain –Text Editor –Compiler/linker/assembler –Debugger Definition

Cost OS (i.e. Windows/Linux/OSX) Supported Programming Languages Supported Hardware Architectures (x86, ARM, etc.) Libraries Real Time Operating Systems(RTOS) Usability Unique Features Product Support Software Development Toolchains: Differentiation

Third Party Toolchains IAR Keil MDK mikroC Green Hills 4

IAR Highly optimizing C and C++ compiler for ARM and other platforms Supports the full range of ARM (7-11), and CortexM(0-4), CortexR(4-7), and CortexA(5-9, 15) Support for over 3100 example projects for many developer boards Supports ARM and Thumb ISAs and ARM EABI Complex debugging including power debugging Support for many different RTOS including freescale, and openRTOS Includes run-time libraries as well as library source code 5

IAR Debugger Supports software simulation of code Supports in-circuit debugging probes Debugger is RTOS aware so debugging can be run even in real-time run environment Support for in hardware debugging using JTAG and many other in-situ debuggers Power debugging to visualize power consumption in correlation with source code 6

Keil MDK Specifically designed for microcontroller applications MDK-Lite, MDK-Basic, MDK-Standard, and MDK- Professional Supports Cortex-M, Cortex-R4, ARM7, and ARM9 Keil RTX: small footprint RTOS Complete Code Coverage –Color coded debugging tool Professional supports: –TCP/IP Networking Suite –USB host/device interface –Flash file system library 7 Code Coverage

mikroC IDE and toolchain by MikroElectronica Intended for Microcontroller-based applications Supports only STMicroelectronics Cortex M3 and M4 Supports hardware debugging, software simulating and function byte size measuring Has various tools like 7 segment display editor and text- to-LCD character editor Includes drivers and libraries for many peripherals including CAN, TFT, Ethernet, FAT16, USB, memory management 8

Green Hills Products RTOS: INTEGRITY –FFS, FAT, NFS, and journaling file systems – IPv4/IPv6 host and routing networking stacks Optimizing compilers for: –C, C++, EC++, MISRA C, Ada –Configurable to per-project, per-file, per-function, or per-source-line IDE: MULTI –C, C++, Ada –Designed to work with Green Hills compilers and debuggers –Enforces strict clean code standards with MISRA 2004 and GHS Standard Mode 9

Green Hills Products Debugger: TimeMachine –One element of debugging suite allows visual debugging of program control flow. –Performance analysis tools to see where program is spending its time –Can view OS events to track undesirable behavior in system 10 TimeMachine debugging element

Pros and Cons IAR: + Support for all ARM processors - Expensive MDK: + Extra support for microcontroller applications - Only Professional edition offers all the perks mikroC: + Visual comments - Only supports STMicroelectronics, Cortex M3 and Cortex M4 Green Hills: + Visual debugging and performance analysis - Buy multiple products 11
