I made some modifications to the note for clarity. Assume some background information from CSCE 430 or equivalent von Neumann architecture Memory holds data and instructions. Central processing unit (CPU) fetches instructions from memory. Separate CPU and memory distinguishes programmable computer. CPU registers help out: program counter (PC), instruction register (IR), general- purpose registers, etc. von Neumann Architecture Memory Unit Input CPU Output Unit Control + ALU Unit CPU + memory address 200PC memory data CPU 200 ADD r5,r1,r3 ADD IRr5,r1,r3 Recalling Pipelining Recalling Pipelining What is a potential Problem with von Neumann Architecture?

Micro-Circuits for High Energy Physics*
MICRO-CIRCUITS FOR HIGH ENERGY PHYSICS* Paul F. Kunz Stanford Linear Accelerator Center Stanford University, Stanford, California, U.S.A. ABSTRACT Microprogramming is an inherently elegant method for implementing many digital systems. It is a mixture of hardware and software techniques with the logic subsystems controlled by "instructions" stored Figure 1: Basic TTL Gate in a memory. In the past, designing microprogrammed systems was difficult, tedious, and expensive because the available components were capable of only limited number of functions. Today, however, large blocks of microprogrammed systems have been incorporated into a A input B input C output single I.e., thus microprogramming has become a simple, practical method. false false true false true true true false true true true false 1. INTRODUCTION 1.1 BRIEF HISTORY OF MICROCIRCUITS Figure 2: Truth Table for NAND Gate. The first question which arises when one talks about microcircuits is: What is a microcircuit? The answer is simple: a complete circuit within a single integrated-circuit (I.e.) package or chip. The next question one might ask is: What circuits are available? The answer to this question is also simple: it depends. It depends on the economics of the circuit for the semiconductor manufacturer, which depends on the technology he uses, which in turn changes as a function of time. Thus to understand Figure 3: Logical NOT Circuit. what microcircuits are available today and what makes them different from those of yesterday it is interesting to look into the economics of producing microcircuits. The basic element in a logic circuit is a gate, which is a circuit with a number of inputs and one output and it performs a basic logical function such as AND, OR, or NOT. -
Implementation, Verification and Validation of an Openrisc-1200
(IJACSA) International Journal of Advanced Computer Science and Applications, Vol. 10, No. 1, 2019 Implementation, Verification and Validation of an OpenRISC-1200 Soft-core Processor on FPGA Abdul Rafay Khatri Department of Electronic Engineering, QUEST, NawabShah, Pakistan Abstract—An embedded system is a dedicated computer system in which hardware and software are combined to per- form some specific tasks. Recent advancements in the Field Programmable Gate Array (FPGA) technology make it possible to implement the complete embedded system on a single FPGA chip. The fundamental component of an embedded system is a microprocessor. Soft-core processors are written in hardware description languages and functionally equivalent to an ordinary microprocessor. These soft-core processors are synthesized and implemented on the FPGA devices. In this paper, the OpenRISC 1200 processor is used, which is a 32-bit soft-core processor and Fig. 1.
