1. Complete the following matrix A. If abstraction Y can implement parallelism grainsize X, set Ax 1 else 0. Assume that the hardware is capable of bit level parallelism and is implemented as such for all scenarios. 2. For each level of parallelism, briefly justify why a particular abstraction can(not) implement it. Please note that there are 16 such (parallelism grainsize, abstraction) pairs, out of which (Bit, Hardware)-1 is an assumption already stated in the question.
