摘要：

This paper presents an implementation of static Huffman encoding hardware for real-time lossless compression in the ECAL of the CMS detector. The construction of the Huffman encoding hardware shows an implementation for optimizing its logic size. The number of logic gates of the parallel shift operation for the hardware is analyzed. Two kinds of implementation methods of the parallel shift operation are compared in aspect of logic size. The experiment with the hardware on a simulated ECAIL environment covering 99.9999% of original distribution shows promising result with the simulation that the compression rate was 4.0039 and the maximum length of the stored data in the input buffer was 44.
