    Threading and multi-threading

    Thread in HW maybe point to one datapath, and multithread for multidatapath. They are very common in operating system based SW design.

    Which DSP should i be using?

    You need to estimate the MIPS cost first. OFDM may need high speed IFFT and channel codec and other signal processing unite such as equalizer. So it is better to choose a very powerful one. ADI also have some DSPs like blackfin shark.

    what is hot-topic in digital design now?

    Uses digital circuits to achieve the RF module's function is a very interesting area. Added after 1 minutes: Digital design for still image processing like digital camera is very hot I think.

    Differences in implementing designs in Asic and FPGA

    fpga vs asic FPGA is not efficient in speed, area and power and it has special memory(dual port), multiplier and clock tree. So, after prototyping, you need to change them.

    what is formal verification

    formal verification may induce "false path" so maybe not 100% safe.
