oc_jpegencode
=============
Fork of OpenCores jpegencode with Cocotb testbench
Fork of OpenCores jpegencode with Cocotb testbench. Uses the Python image library to send files through the encoder.
Original project page on Opencores: http://opencores.org/project,jpegencode
To run the testbench:
# Pre-requisites
sudo yum install -y python-imaging
git clone https://github.com/potentialventures/cocotb.git
git clone https://github.com/chiggs/oc_jpegencode.git
export COCOTB=`pwd`/cocotb
cd oc_jpegencode/tb
make

/* This is the top level module of the JPEG Encoder Core.
This module takes the output from the fifo_out module and sends it
to the ff_checker module to check for FF's in the bitstream. When it finds an
FF, it puts a 00 after it, and then continues with the rest of the bitstream.
At the end of the file, if there is not a full 32 bit set of JPEG data, then the
signal "eof_data_partial_ready" will go high, to indicate there
are less than 32 valid JPEG bits in the bitstream. The number of valid bits in the
last JPEG_bitstream value is written to the signal "end_of_file_bitstream_count".
