Custom Instruction examples

I have created a set a custom instructions that demonstrate the various different types of custom instructions: 

 

here is a quote from the intro in my tutorial:

Introduction 

 

      ... this tutorial came bundled with several custom instruction examples which cover many different types of possibilities; such as, internal registry options, I/O options, and stalling options.  Examples below use a multiply accumulate (MAC) example from a basic instruction to one that takes advantage of many sophistication options.  A MAC is an operation which takes an input and multiplies it with its current value and then accumulates it.  The basic functionality of a MAC can be found in an included custom instruction user guide on page 1-11.  A Taylor series calculator and a “blinker” custom instruction that interacts with the LEDs are also included.  The Taylor series calculator can be used to approximate functions while the LED blinker demonstrates IO with custom instructions. ...[/b]

Unlike many other custom instructions, some of the ones in this bindle are non-stalling, which speeds up computation, and some that are IO capable. 

 

Note: with the Altera custom instruction guide the file size was too large. So, you can find it at
