WHY I3C BASIC IS PREFERRED MORE?

 The I3C communication protocol (pronounced eye-three-see) is a MIPI Alliance standard developed by Sensor Working Group. The name refers to the bus's resemblance to I2C, as it uses the identical two-wire SCL and SDA lines and is backward compatible with I2C. (with some caveats). To get the full I3C standard, you must be a member of MIPI. However, the MIPI Alliance website offers a free download of a publicly available subset of the full specification called MIPI I3C Basic.

I3C Basic

 

MIPI I3C v1.0 was the first public release of the I3C standard by the MIPI Alliance in late 2017. Members of the MIPI Alliance had access to the standard prior to its official release. In October of 2018, MIPI I3C Basic v1.0 was released. In December of 2019, MIPI I3C v1.1 was released. According to the MIPI I3C Basic specification, I3C consumes significantly less energy and has a faster bus speed than I2C. The ability of I3C to transition from open-drain to push-pull drive in certain modes enables the speed advantage over I2C. I2C operates with an open-drain drive at all times, limiting the signal's rising time (the signal is pulled high by a "slow" resistor). Once the initial bus arbitration has occurred, I3C can move from open-drain to push-pull communication, allowing for substantially faster communication (up to rates comparable with SPI).

External pull-up resistors are not required for I3C; the pull-up resistors are provided by the I3C master (s). I2C devices can communicate with I2C and I3C nodes at I2C bit rates when attached to an I3C bus. When an I3C node communicates with another I3C node, the standard permits the bit rate to rise. I2C slaves are supported on an I3C bus, but not I2C masters (the master on an I3C Basic must be an I3C device).

"Boosting Data Transfer Efficiency: Understanding AXI Stream DMA, AXI4 Stream DMA, and eSPI IP"

Image
I n the world of computer engineering, data transfer efficiency is a crucial aspect of system performance. As technology evolves, new methods for data transfer are constantly being developed to ensure faster and more efficient communication between system components. Three such methods are AXI Stream DMA, AXI4 Stream DMA, and eSPI IP. In this blog, we will explore these technologies and their benefits in more detail.  AXI Stream DMA An AXI Stream Direct Memory Access (DMA) is a method of transferring data between an AXI4 Stream master and a memory-mapped AXI4 slave. The AXI Stream DMA engine allows for efficient data transfer between the master and slave by utilizing a direct memory access controller. This controller is responsible for managing data transfer between the two components, freeing up the processor for other tasks. AXI Stream DMA also has the added benefit of being able to transfer data in both directions, making it a v...

  MIPI I3C is a two-wire interface with a bidirectional data bus for connecting sensors to an application processor. MIPI I3C is a specification to enable communication between computer chips by defining the electrical connection between the chips & signaling patterns to be used. The standard defines the electrical connection between the chips to be two wires, shared, serial data bus, one wire being used as a clock to define the sampling times, the other wire being used line whose voltage can be sampled. Functions & Application of MIPI I3C: The I3C Basic includes many protocol innovations in I3C 1.0 but lacks some of the potentially more difficult to implement ones such as the optional high data rate (HDR) modes like DDR The MIPI I3C is available for implementation of intended to facilitate a royalty-free licensing environment for all implementers, as described within the specification. I3C main builds on the capabilities of I2C and the ecosystem that has grown ...
