Overview
The I2C is a two-wire, bi-directional serial bus, which provides a simple and efficient method of short distance data transmission between many devices. The DI2CMS core provides an interface between a microprocessor/microcontroller and an I2C bus. It can work as a master or a slave transmitter/receiver - depending on a working mode, determined by the microprocessor/microcontroller. The DI2CMS core incorporates all features required by the latest I2C specification, including clock synchronization, arbitration, multi-master systems and a high-speed transmission mode (the DI2CMS supports all the transmission speed modes). Built-in timer allows operation from a wide range of the clk frequencies.
The DI2CMS is technology independent, that's why a VHDL or VERILOG design can be implemented in a variety of process technologies. Furthermore, it can be also completely customized in accordance to the customer's needs.
The DI2CMS is delivered with fully automated testbench and complete set of tests, allowing easy package validation at each stage of SoC design flow.

This article focuses on the most important details of the modern SPI interfaces, which are improved by many useful features. But to start, let us discover the history of the modern SPI interface, because even the old, most basic SPI interfaces are still in use.
D32PRO is one of the newest 32-bit CPUs available on the market. It’s been designed by Digital Core Design, IP Core provider and SoC design house from Poland, responsible e.g. for the world’s fastest or world’s smallest 8051 CPU. DCD launched more than 70 different architectures since 1999, which have been implemented in more than 300 000 000 electronic devices, that’s why one can be sure that quite considerable experience stands behind the D32PRO.
