Complex Programmable Logic Device (CPLD)

• is a programmable logic device with complexity between that of PALs and FPGAs
• contains a bunch of PLA/PAL blocks whose inputs and outputs are connected together by a global interconnection matrix. So a CPLD has two levels of programmability:
  • each PLA/PAL block can be programmed
  • and then the interconnections between the PLA/PAL blocks can be programmed
