SPI lends itself to a "bus driver" software design. Software for attached devices is written to call a "bus driver" that handles the actual low-level SPI hardware. This permits the driver code for attached devices to port easily to other hardware or a bit-banging software implementation.
Embedded software needs to include all needed device drivers at manufacturing time, and the device drivers are written for the various hardware devices. These device drivers, called BSP (Board support package), form the layer of software containing hardware-specific drivers and other routines that allow a particular operating system ...

Some very low-cost home computers or embedded systems that lack a physical UART may instead emulate the protocol with software by sampling the state of an input port or directly manipulating an output port for data transmission. While very CPU-intensive (since the CPU timing is critical), the UART chip can thus be omitted, saving money and space.
An embedded system on a plug-in card with processor, memory, power supply, and external interfaces. An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.
Low Pin Count interface Winbond chip Trusted Platform Module installed on a motherboard, and using the LPC bus. The Low Pin Count (LPC) bus is a computer bus used on IBM-compatible personal computers to connect low-bandwidth devices to the CPU, such as the BIOS ROM (BIOS ROM was moved to the Serial Peripheral Interface (SPI) bus in 2006 [1]), "legacy" I/O devices (integrated into Super I/O ...
For the full year, we achieved organic revenue growth of almost 10%, adjusted earnings-per-share growth of 12.4%, and free cash flow growth of 21%. We also repurchased $810 million worth of MSCI ...
Embedded hardware, such as the Game Boy Advance, typically have a small amount of RAM accessible with a full 32-bit datapath; the majority is accessed via a 16-bit or narrower secondary datapath. In this situation, it usually makes sense to compile Thumb code and hand-optimise a few of the most CPU-intensive sections using full 32-bit ARM ...
