Building on UC Berkeley RISC and Sun compiler and operating system developments, SPARC architecture was highly adaptable to evolving semiconductor, software, and system technology and user needs. The architecture delivered the highest performance, scalable workstations and servers, for engineering, business, Internet, and cloud computing uses.
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
His most recent book is with Andrew Waterman on the open architecture RISC-V: The RISC-V Reader: An Open Architecture Atlas (1st Edition) (ISBN 978-0999249109). His articles include: Patterson, David; Ditzel, David (1980). "The Case for the Reduced Instruction Set Computer" (PDF). ACM SIGARCH Computer Architecture News. 8 (6): 5– 33.

An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
Hennessy has a history of strong interest and involvement in college-level computer education. He co-authored, with David Patterson, two well-known books on computer architecture, Computer Organization and Design: the Hardware/Software Interface and Computer Architecture: A Quantitative Approach, [5] which introduced the DLX RISC
The DLX is essentially a cleaned up (and modernized) simplified Stanford MIPS CPU. The DLX has a simple 32-bit load/store architecture, somewhat unlike the modern MIPS architecture CPU. As the DLX was intended primarily for teaching purposes, the DLX design is widely used in university-level computer architecture courses.
In the history of computer hardware, some early reduced instruction set computer central processing units (RISC CPUs) used a very similar architectural solution, now called a classic RISC pipeline. Those CPUs were: MIPS , SPARC , Motorola 88000 , and later the notional CPU DLX invented for education.
