PCI bus target controller implementation using a Lattice CPLD

What are CPLDs?
A complex programmable logic device (CPLD) is a programmable logic device with complexity between that of PALs and FPGAs, and architectural features of both. It is made up of several simple PLDs (SPLDs) with a programmable switching matrix in between the logic blocks. CPLDs typically use EEPROM, flash memory or SRAM to hold the logic design interconnections.
