5 Key Steps to Firmware Architecture and Design in 2019
The ultimate success of an embedded system project depends both on its software and hardware.

Let's see software, more specifically firmware architecture and design steps we follows at Inditronics :
Before we can begin to architect an embedded system or its firmware, we must have clear requirements. Properly written requirements define the WHAT of a product.
Select below elements according to identified product requirements.
Processor platforms - ARM Cores, Microchip PIC series, Atmel AVR series, Intel 8051, STM8/32 series etc
Language - C, C++, Java, Python etc
OS - Linux, Android, Windows etc
Hardware device drivers and communication protocols - Serial NOR Flash and Flash File Systems, GPS processing, Bluetooth, GSM / CDMA / LTE cellular communications, I2C, SPI, USART, USB etc.
Development tools - Keil C Compiler, Rowley Crossworks, IAR Workbench, Microchip MPLAB, ST Visual Developer etc
In-circuit emulation tools - JTAG, ST-Link, Microchip MPLAB ICD etc
3. The Design -
Coding finite length firmware
Analyze and expose memory cost
Coding FW with memory costs
Run time budget
Coding cycle accurate FW
Relocatable assembly coding
Design the Datapath
Instruction set design
Build Control Logic
Design the Address Path
4. Design for test -
5. Porting and Testing
Do the interfaces and connections. Generate and verify the machine code. Port the programs into device and test the embedded system.
