Exploring Application Specific Programmable Logic Devices Class 1: An Introduction to Application Specific Programmable Logic Devices 6/10/2013 Warren Miller

This Week’s Agenda 6/10/13 Introduction 6/11/13 Programmable Analog Pt 1 6/12/13 Programmable Analog Pt 2 & Timing 6/13/13 MCUs with Programmable Fabric 6/14/13 Programmable Devices with a New Twist

Class Description Application specific programmable logic devices are not just for digital logic replacement: Non-programmable functions, analog capabilities, timing circuits, etc. This course will provide a detail overview of many of these new devices and will show specific examples of applications where these devices are being used today.

Today’s Topics Goals and Objectives Traditional Programmable Logic Devices- CPLDs and FPGAs Glue Logic ASIC Replacement Typical Applications How to classify Application Specific PLDs? Non-Traditional Programmable Logic Devices- add one or more of: Fixed Function Application Specific Digital Hardware Analog Blocks Alternate Programming Technology Devices and Families to be covered in future classes

Goals and Objectives Understand, at the overview level, key concepts we will use in the rest of the class Traditional Programmable Logic Devices Technology Features and applications Non-Traditional Programmable Logic Devices Technology, features and applications Types of application ‘problems’ not adequately addressed by traditional programmable logic devices

Traditional Programmable Logic Devices- CPLDs and FPGAs Programmable Array Interconnect Matrix Flash Low Capacity Low Cost FPGAs: Configurable Look-up Tables Programmable Interconnects Switch Matrix SRAM-based/Flash-based High Capacity

PLDs PLDs: Programmable Array Full Interconnect One Time Programmable Low Capacity Low Cost Software Easy Architecture Difficult to Extend

CPLDs CPLDs: CMOS Technology Blocks of PLA/PAL Programmable Interconnect Low Capacity Low Cost Software More Difficult Architecture Extendable Note: Logic Tied to I/Os

FPGAs FPGAs: Look-up Tables for Logic Switched Interconnect SRAM (typically) High Capacity High Cost Software Very Difficult Architecture Very Extendable Easy to add Fixed Blocks

FPGAs FPGAs: Include some fixed functions to improve implementation of ‘real’ systems Block Memory Arithmetic Functions Multiplier/MAC Carry Chain Clocking PLLs Buffers Serial IO (SerDes) Processors

Traditional Programmable Logic Devices- Example Applications CPLDs Glue Logic Bridges Timing Control and State machines FPGAs Complete Subsystems Control, Data path, Serial communications, ALU, DSP, Memory Blocks, etc.
