1. 1. Design of an FPGA Based JTAG Recorder for use in Production of IPTV Set-Top Boxes

   Uppsats för yrkesexamina på avancerad nivå, Datorteknik

   Författare :Robert Andreasson; [2009]
   Nyckelord :JTAG; FPGA; Set-Top Box; DDR SDRAM; UART;

   Sammanfattning : This thesis evaluates the possibility to replace the manufacturer dependent JTAG device used in the production tests of IPTV set-top boxes for storing the boot loader in the main memory in order to start the box for the first time. An FPGA based prototype was built in order to see if it is possible to record the JTAG signals, to an external DDR SDRAM, without understanding them and be able to perform a delayed playback resulting in the same bahavoir as with the original JTAG device.

3. 2. Design of a Gigabit Router Packet Buffer using DDR SDRAM Memory

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Daniel Ferm; [2006]
   Nyckelord :DDR; SDRAM; memory; FPGA; ethernet; router; socbus;

   Sammanfattning : The computer engineering department at Linköping University has a research project which investigates the use of an on-chip network in a router. There has been an implementation of it in a FPGA and for this router there is a need for buffer memory. LÄS MER
