  • Design and Implementation of a Head of Line Blocking (HOLB) Solution

    Problem Description: Network routers by nature handle thousands of mega packets per second. Each packet might come from one port and be destined to another port. The actual routing decision is made only once the packet is received and inspected. This scheme by definition, causes head of line blocking, in which one packet destined to a blocked destination completely blocks the input queue or the common processing pipeline. These kinds...

  • BCH Error Detection and Correction for SRAM

    The Bose, Chaudhuri, and Hocquenghem (BCH) codes form a large class of powerful random error-correcting cyclic codes. This class of codes is a remarkable generalization of the Hamming code for multiple-error correction. BCH codes are used in varied applications such as satellite communications, compact disc players, DVDs, disk drives, solid-state drives, two-dimensional bar codes, SRAMs, etc. This project proposes building a designated BCH IP core, which can be configured to...

  • Implementation of a Digital OFDM Transciever

    Orthogonal Frequency Division Multiplexing (OFDM) is a Frequency Division Multiplexing (FDM) technique used as a digital multi-carrier modulation method. Instead of using one high speed channel, the data is split into a large number of lower speed channels. Orthogonal sub carriers are used to carry data on several parallel data streams which allows more efficient use of the spectrum compare to regular FDM. Orthogonality of the carriers prevents interference between...
