Description

The VMEbus was first standardized in 1981 and is still in wide use. With the

advances in integration technologies, custom integrated VME controllers open the

door for smaller and cheaper systems. Inicore offers a wide range of different VME

slave controllers. Each one optimized for a certain application. The difference lies

mainly in the address and data bus width and the supported data modes.

The VME slave controller shields all the complexity of the asynchronous VMEbus

and provides an easy-to-use, synchronous parallel user side interface towards

custom logic. A built-in interrupter handles all local interrupt requests and

acknowledgments.

Figure 1: Sample application

The figure above illustrates a typical application where several peripheral

functions together with the VME slave core as well as a bus bridge are integrated

into one FPGA.
