Over the last few years, PCI Local Bus has emerged as the strongest and most widely used bus system in
the option card bus industry that used to have been dominated by ISA/EISA. We expect that this trend will
continue for substantial amount of time thanks to convenience and high performance of PCI BUS. It is also
expected that PCI Local Bus will expand its application even further as the PCI families such as CompactPCI,
PCI-X and mini PCI are developed, over the conventional PCI types, to provide various types of solution.
Therefore, PCI Local Bus becomes the most important factor to be considered in the electronics industry.
While PCI Local Bus is powerful and has many convenient functions, however, difficulty in developing PCI
becomes a burden for the developers. There are companies who provide the PCI target board developers
with the PCI target interface one chip solution or the FPGA embedded PCI core solution. Because these
suppliers are from USA and Taiwan, the developers in other countries suffer difficulty in analyzing solutions,
lack of technical support and high price.
In this context, SystemBase has released SB4001 which enabled the users to develop PCI target boards
with reduced cost. SystemBase releases SB4002A with improved features at the same price level. Because
SB4002A is compatible with its previous model, you can easily use the new model without trouble. SB4002A
also provides an easy-to-use interface for the developers who have never used SystemBase chip before.
SystemBase has developed the PCI boards with the PCI target interface core built-in, and SB4001 adopted
in the products of SystemBase has been proven in the field for years. Developed based on the know-how
