== Compute Engine Design Specifications ==

The COMPUTE ENGINE of SCOORE is responsible for all the calculations of the processor. SCOORE is a clustered architecture, we have FOUR main units which comprise the COMPUTE ENGINE.

  1. AUNIT is responsible for all the "simple arithmetic operations" of the CPU.(Single Port)
  2. BUNIT is responsible for branch operations. (Dual Port)
  3. CUNIT handles all floating point operations. (Single Port)
  4. MUNIT handles all Load and Store operations. (Dual Port)

A more detailed description of each individual block is given below.
