In this paper, the RUNCODE encoder hardware IP was designed and implemented for symbol ID code length encoding, which is one of major modules of JBIG2 encoder for FAX. ImpulseC Codeveloper and Xilinx ISE/EDK program are used for the hardware generation and synthesis of VHDL code. The synthesized hardware was downloaded to Virtex-4 FX60 FPGA on ML410 development board. The synthesized hardware utilizes 13% of total slice of FPGA. Using Active-HDL tool, the hardware was verified showing normal operation. Compared with the software operating using Microblaze cpu on ML410 board, the synthesized hardware was better in operation time. The improvement ratio of operation time between the synthesized hardware and software showed about 40 times faster than software only operation. The synthesized H/W and S/W module cooperated to succeed in compressing the CCITT standard document.
