Reasons to choose i3C Basic IP

 

The Sensor Working Group created the MIPI Alliance standard known as i3C, which is pronounced: "eye-three-see." The name alludes to the bus's similarity to i2C because it is backwards compatible with i2C and uses the same two-wire SCL and SDA lines. (With some restrictions) You must belong to MIPI in order to receive the complete i3C standard. However, a publicly accessible subset of the full specification called MIPI i3C Basic IP is available for free download from the MIPI Alliance website. 

 

The MIPI Alliance released the i3C standard's first public version, version 1.0, in late 2017. Prior to the formal release of the standard, members of the MIPI Alliance had access to it. MIPI i3C Basic v1.0 was released in October 2018. 2019 saw the release of MIPI i3C v1.1 in December. i3C uses less energy than i2C and offers a quicker bus speed, per the MIPI i3C Basic IP  specification. i3C has a speed advantage over i2C because it can switch from an open-drain to a push-pull drive in some situations. i2C always uses an open-drain drive, which reduces the signal's rising time (the signal is pulled high by a "slow" resistor).i3C can switch from open-drain to push-pull communication after the initial bus arbitration, enabling noticeably quicker communication (up to rates comparable with SPI).

  

 

i3C sometimes doesn't require external pull-up resistors; instead, the i3C master offers the pull-up resistors (s). When linked to an i3C bus, i2C devices can communicate at i2C bit rates with i2C and i3C nodes. The standard allows the bit rate to be higher when an i3C node communicates with another i3C node. On an i3C bus, i2C slaves are supported 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 ...
