1. The DLX Instruction Set. Architecture. DLX Architecture Overview. ? Pronunced delux. ? (AMD 29K, DECstation 3100, HP 850, IBM 801,. Intel i860, MIPS M/120A, MIPS M/1000, Motorola. 88K, RISC I, SGI 4D/60, SPARCstation-1, Sun-. 4/110, Sun-4/260)/13 = 560 = DLX. ? Simple Load/Store architecture. ? Functions that
From the Publisher: The definitive source for the DLX instruction set architecture introduced in John L. Hennessy and David A. Patterson's Computer Architecture: A Quantitative Approach. DLX is a selective amalgam of several sophisticated load/store architectures; it was developed to serve as a simple example of a pure
DLX instructions can be broken down into three types, R-type, I-type and J-type. R-type instructions are pure register instructions, with three register references contained in the 32-bit word. I-type instructions specify two registers, and use 16 bits to hold an immediate value. Finally J-type instructions are jumps, containing a
Less common cases via software. • Provide primitives. – Simple load-store instruction set. • Entire instruction set fits on a page. – Efficient pipeline via fixed instruction set encoding. – Compiler efficiency. • Lots of general purpose registers. DLX Registers. • 32 GPRs, can be used for int, float, double. • 32 bits for R0..R31, F0.
HASE Scoreboard Project. HASE DLX Model - Instruction Set. The HASE Simulation Model of the DLX with Parallel Function Units implements most of the instructions defined in Sailer & Kaeli, as shown in the figure. In the DLX instruction set architecture: 1. DLX arithmetic assembly code instructions are of the form: rd <- rs1
Of course, the machine based on the DLX instruction set is a total work of fiction. If one existed, however, it would be a 32 bit machine, i.e., each word would be four bytes. DLX is Big Endian, as opposed to Little Endian, which means that a DLX address first accesses the byte in the most significant position when it's getting a

Note that 8 instructions have been added to this version of the instruction set that do not appear in Hennessy and Patterson's text; nor are they listed in "The DLX Instruction Set Architecture Handbook" by Sailer and Kaeli, which otherwise was used as a guideline to the instruction set specification. The new instructions are
