What is firmware architecture?

Architecture of a firmware (FW) in a way defines the life-cycle of your product. That way, similar products can be derived from the same code base with addition of new modules or modification of existing modules that would do the differentiation. In any case, most of the modules will be reused to develop a new product.

Could you describe firmware architecture?

The firmware architecture diagram identifies subsystem-level blocks such as device drivers, RTOS, middleware and major application components. At the time of architecture of firmware system, the various features are used for managing time such as a mix of non-real-time, soft-real-time, and hard real-time requirements.

How do you make a firmware?

Firmware architecture in five easy steps

  1. Step 1: Identify the requirements. Before we can begin to (re)architect an embedded system or its firmware, we must have clear requirements.
  2. Step 2: Distinguish architecture from design.
  3. Step 3: Manage time.
  4. Step 4: Design for test.
  5. Step 5: Plan for change.

What is firmware framework?

The firmware framework maintains an execution scheduling table, pFwTaskExecuteScheduleTable[] , with one down-counter for each task. There is no reload functionality, which means that the Sensor Controller must always call fwScheduleTask(delay) to set up the next execution ( delay ticks after the current tick).

What is the difference between OS and RTOS?

In general, an operating system (OS) is responsible for managing the hardware resources of a computer and hosting applications that run on the computer. An RTOS performs these tasks, but is also specially designed to run applications with very precise timing and a high degree of reliability.

What is DD-WRT based on?

DD-WRT (DresDren-Wireless RouTer) is a type of firmware for routers based on the Linux kernel. It was designed especially for 802.11a/b/g/h/n routers having the Broadcom or Atheros chipsets. This firmware is registered under GPL and free software licenses and supports a large variety of wireless routers.
