  1. Show 128-bit data for SSE in proper endian order, for 8-bit, 16-bit, 32-bit, and 64-bit block sizes.

  2. 128 bits = four single-precision floats. How wide would the next generation processor have to be for quad vector double-precision? Write a memory handler for this new hypothetical type processor.

  3. Future super matrix processors will be able to number-crunch entire matrices at a time. How wide would the data path be? Write an alignment macro for that width. Hint: There are two primary solutions!

  4. Earlier in this chapter the function HexDmp32() demonstrated a 32-bit (8 ASCII byte) hex dump. Write a slightly different function that prints a string of 8-bit bytes in hex of a specified count.

     void HexDmp(byte *pData, uint nCount);
