SAP-1 Simple As Possible Computer - Discrete Digital Logic SAP-1 Simple As Possible Computer It can do everything except save or print, so the circuit can be simulated when opened (use the Import Legacy Design). Unfortunately the original design uses 74LS189 16x4-bit RAM, which can only be found on eBay right now. Sap 1 - SlideShare Saturday, April 25, 2015www 2 SAP-1 is the first stage in the evolution towards modern computers. The main purpose of SAP is to introduce all the crucial ideas behind computer operations. Being a simple computer, SAP-1 also covers many advanced concepts. SAP-1 Education for ALL: SAP-1 Architecture SAP (Simple-As-Possible)-1 is the first stage in the evolution toward modern computers. Functional Block Diagram of 8086 Microprocessor. Timing Diagram for MOV A,B. SAP-1 Architecture. C Program to Draw a SMILEY FACE using Ellipse, Circle and Arc in Graphics. Differences between 8086 Discrete Digital Logic Circuits: SAP-1 with a Microcoded ROM Here is my attempt at designing a SAP-1 microprocessor with a micro-code ROM controller sequencer and a variable machine cycle. The total number of ICs has decreased from 48 to 35. My design deviates a bit from the block diagram shown at the end of chapter 10. Looking at Digikey's catalogue, 16x4-bit or 16x8-bit ROMs are simply not available Design of 8-bit microprocessor using Verilog (SAP-1 PDF fileDesign a 8-bit microprocessor using Verilog and verify it's operations. Use SAP-1 (Simple As Possible) architecture as your reference. Introduction The Simple-As-Possible (SAP)-1 computer is a very basic model of a microprocessor explained by Albert Paul Malvino1. The SAP-1 design contains the basic necessities for a functional Microprocessor.
