Scope of this Document

The EMP framework provides common infrastructural firmware - as well as corresponding control and monitoring software - to support arbitrary user-created payload firmware, e.g. the reconstruction algorithm in a level-1 track finder or level-1 trigger board.

The scope of this infrastructural firmware and software includes:

• a control bus master;

• TTC generation and reception;

• the transmission and reception of data over high-speed electrical links and optical links;

• the use of the datapath buffers to load user-specific data patterns over the control bus, play this input data into the payload, capture payload’s output data, and read that over the control bus

• The basic idea
• Walkthroughs for First Users
• EMP firmware
• EMP software
• Reference bitfiles
• Release notes

Notably:

• The Walkthroughs for First Users page explains how to integrate custom “physics algorithm” payload firmware into the framework.

• The Testing payload firmware in a single FPGA page explains how to use the software to:

  1. load data onto the input buffers;

  2. “play” it through the payload firmware; then

  3. capture and read back the contents of the output buffers.
