The System Management Bus (abbreviated to SMBus or SMB) is a single-ended simple two-wire bus for the purpose of lightweight communication. Most commonly it is found in chipsets of computer motherboards for communication with the power source for ON/OFF instructions. The exact functionality and hardware interfaces vary with vendors.
Version 3.7.0 was released in July 2023. Contents. The SMBIOS table consists of an entry point (two types are defined, 32-bit and 64-bit), and a variable number of structures that describe platform components and features. These structures are occasionally referred to as "tables" or "records" in third-party documentation. Structure types
I 2 C 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 I 2 C hardware. This permits the driver code for attached devices to port easily to other hardware, including a bit-banging design. Example of bit-banging the I 2 C protocol
Bus (computing) In computer architecture, a bus [1] (historically also called data highway [2] or databus) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
RS-MMC. In 2004, the Reduced-Size MultiMediaCard ( RS-MMC) was introduced as a smaller form factor of the MMC, with about half the size: 24 mm × 18 mm × 1.4 mm. The RS-MMC uses a simple mechanical adapter to elongate the card so it can be used in any MMC (or SD) slot. RS-MMCs are currently available in sizes up to and including 2 GB.
In computing, an input–output memory management unit ( IOMMU) is a memory management unit (MMU) connecting a direct-memory-access –capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses, the IOMMU maps device-visible virtual addresses (also called ...
Windows Driver Model. In computing, the Windows Driver Model ( WDM ) – also known at one point as the Win32 Driver Model – is a framework for device drivers that was introduced with Windows 98 and Windows 2000 to replace VxD, which was used on older versions of Windows such as Windows 95 and Windows 3.1, as well as the Windows NT Driver Model .
The STM32 is a family of microcontroller ICs based on various 32-bit RISC ARM Cortex-M cores. [1] STMicroelectronics licenses the ARM Processor IP from ARM Holdings. The ARM core designs have numerous configurable options, and ST chooses the individual configuration to use for each design.
