SDRAM controller for Patmos in Chisel[edit | edit source]

The project will mainly focus on porting the controller for SDRAM written in VHDL to Chisel for the Altera DE2-115 board.

>>>>>>>>>>>>>>>>>>SPM project<<<<<<<<<<<<<<<<<<<<<<<<<<

Implementation of a shared scratch-pad memory with a concept of ownership for multiprocessor architectures.

The project will investigate:

  1. Implementation of shared SPM with a ownership concept (probably a time-division
  2. Synchronization and support for atomic operations
  3. Investigation of possible applications and programming models

Project Topic: Branch Predictor for Patmos

Three things must predicated in order to implement a branch predictor:

  • Whether the fetched instruction is a branch
  • (Conditional) Branch Direction
  • Branch Target Address

The first and the third issue can be resolved by implementing a Branch Target Buffer (BTB).

The second issue can be resolved either by static or dynamic analysis.

In our project we are going to use dynamic analysis by using at first 1-bit counter based prediction, then 2-bit counter based prediction and if we have time we will implement a correlated branch predictor.

Finally, we will compare the different execution times of "taclebenchmarks" on the different implementations.

Topic: TinyOS on Patmos


1. Investigate the TinyOS tutorials to get a better feeling about the operating system and especially about the programming language nesC.

2. Determine what drivers have to be ported.

3. Make the necessary changes to have the new board compatible with TinyOS.
