    F28335 is single precison floating point device

    F2808 is a fixed point device,

    I am not sure when you say multiplication/ division and addition you mean fixed point or floating point?

    F2808 has instructons to add and multiply two fixed point numbers, which will be 1-2 cycles each.

    F28335 has everything that F2808 has , but also instructions for multiplcation , addition and a lower precison division for floating point numbers which are 1-2 cycles each.

    FIXED POINT ARITHMETIC

    You can find this information related to c28x core in the following guide.
    www.ti.com/.../spru430f.pdf

    C28x can perform 1 /32 bit and 2/ 16-bit (parallel) multiplications in a cycle. And addition and subtraction both in a cycle as well.

    FLOATING POINT ARITHMETIC

    Floating point arithmatic is performed in a FPU. Please take a look at in the following document.
