The ISA specifies the memory organization, register set, and instruction set, including opcodes, data types, and addressing modes. 5.1.1 Memory Organization.Aug 4, 2005 - Little Computer 3, or LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language. It features a relatively simple instruction set, but can be used to write Print/export. Download as PDF · Printable version LC-3 Overview: Registers LC3 interleaves instructions and data in one 216 word memory Some opcodes set/clear CC (condition codes), based on result. The Instruction Set Architecture (ISA) of the LC-3 is defined as follows: Memory address All other LC-3 instructions leave the condition codes unchanged. •Type of operation to perform (opcode). •Where to get source operands. •Where to put result (destination). We will consider a specific baby instruction set: LC3 The Instruction Set Architecture (ISA) of the LC-3b is defined as follows: Memory mapped I/O Input and Output are handled by load/store instructions using The Instruction Set Architecture (ISA) of the LC-3 is defined as follows: Memory address All other LC-3 instructions leave the condition codes unchanged. 4.
