Paper Abstract 

SPI Xpress is Byte Paradigm’s SPI protocol exerciser and analyzer. It is controlled from a PC through a USB 2.0 high speed interface. It allows debug, analysis, programming and testing of chips and electronic boards that use SPI for chip-to-chip communications.

It operates on standard SPI and many other serial protocol interfaces that slightly differ from the standard SPI protocol, including 3-wires interfaces with bidirectional data line, up to 50 Mbps data rate. 

Being capable of interfacing serial protocol that slightly differ from the standard SPI is a unique feature that helps many ASIC, SoC, FPGA and embedded system designers being more productive at testing and debugging tasks.

SPI Xpress is delivered with its control software (MS-Windows) including graphical user interface, waveform viewer, scripting TCL/tk interface and direct C/C++ DLL access.

This white paper introduces the unique features of the SPI Xpress Master / Analyzer.
