High Level Abstraction Language as an Alternative to Embedded Processors for Internet Packet Processing in FPGA

In this paper, we investigate three different realizations of the same block from different points of view. The mentioned different realizations include two realizations with embedded processors (custom 16-bit RISC processor and general soft-core processor) and the third realization uses Handel-C as an example of synthesisable high-level abstraction languages. The results show that development time of complete solution (HW and SW) is approximately the same for the Handel-C design and the design with soft-core processor; the development time of the Custom 16-bit RISC processor is about five times higher. Moreover, the throughput of the Handel-C design measured in the number of bits processed in one second is the highest. The obtained frequency and occupied area of the Handel-C design depends on the complexity of the used program. However, results are comparable or even better than results of the embedded processors.
