DLX Processors Components

DLX Processors Components

The DLX is a reduced instruction set computer (RISC) processor architecture. It is mainly a cleaner, simpler MIPS architecture, with a simple 32-bit load/store design, and intended mainly for education, as are Donald Knuth's MIX and MMIX architectures. All three are widely used in college-level computer architecture courses. DLX was introduced in the textbook "Computer Architecture: A Quantitative Approach", by John L. Hennessy and David A. Patterson, the main designers of the MIPS and Berkeley RISC designs, respectively, which are the two benchmark RISC designs.
