Question

12. What is the major difference between a SPLD (Simple Programmable Logic Device) and a CPLD (Complex Programmable Logic Device) ?

Answer 1

First of all, SPLDs and CPLDs are the two types of Programmable Logic Devices(PLDs). The main difference is

  >>SPLDs devices typically contain the equivalent of 600 or fewer gates,

>>while CPLDs, by contrast, offer up to about 10,000 gates But CPLDs offer very predictable timing characteristics and are therefore ideal for critical control applications. Some CPLDs require extremely low amounts of power and are very inexpensive.

>>>A simple programmable logic device (SPLD) is a programmable logic device with complexity below that of a complex programmable logic device (CPLD).
