Reduced Instruction Set Computer (RISC). Instruction Types All DLX instruction are 32 bits and must be aligned in memory on a word boundary 3 instruction format I-type (Immediate): manipulate data provided by a 16 bit field R-type (Register): manipulate data from one or two registers J-type (Jump): provide for the executions of jumps that do not use a register operand to, Complete list of the instructions in DLX. Instruction type/opcode: Instruction meaning: Data transfers: Move data between registers and memory, or between the integer and FP or special register; only memory address mode is 16-bit displacement + contents of a GPR.

Lecture-2 (Instruction Set Architecture) CS422-Spring 2018. Another version of this core implements the RV32I base user level instruction set of the RISC-V architecture. The core organization is basically the same as HF-RISC, including the memory map and software compatibility (a given application just has to be recompiled to the RV32I target). •Instruction sequencing increments a Program Counter °Sequencing flow is disrupted conditionally and unconditionally •The ability of computers to test results and conditionally instructions is one of the reasons computers have become so useful Instruction 1 Instruction 2 Instruction 3 Instruction 1 Instruction 2 Conditional Branch.
