Total Contact Hours – 75 Prerequisite:Nil PURPOSE To enable the student to understand the RISC (ARM) and CISC (Pentium) processors, which will be useful for designing high end embedded systems. INSTRUCTIONAL OBJECTIVES 1. To learn RISC and CISC architectures of processors. 2. To learn ARM processor and its programming with Embedded C. 3. To learn to use ARM development tools and carry out experiments UNIT I - MICROPROCESSOR ARCHITECTURE (9 hours) Instruction set - Data formats - Instruction formats - Addressing modes - Memory Hierarchy register file - Cache - Virtual memory and paging - Segmentation - Pipelining - The instruction pipeline - pipeline hazards - Instruction level parallelism - reduced instruction set - Computer principles - RISC versus CISC - RISC properties - RISC evaluation - On-chip register files versus cache evaluation. UNIT II - HIGH PERFORMANCE CISC ARCHITECTURE – PENTIUM (9 hours) The software model - functional description - CPU pin descriptions - RISC concepts - bus operations - Super scalar architecture - pipelining - Branch prediction - The instruction and caches - Floating point unit - protected mode operation - Segmentation - paging - Protection - multitasking - Exception and interrupts - Input/Output - Virtual 8086 model - Interrupt processing - Instruction types Addressing modes - Processor flags - Instruction set - Basic programming the Pentium Processor.Lab exercise. UNIT III - HIGH PERFORMANCE RISC ARCHITECTURE (24 hours) ARM: The ARM architecture - ARM organization and implementation - The ARM instruction set The thumb instruction set - Basic ARM Assembly language program - ARM CPU cores. ARM DEVELOPMENT ENVIRONMENT The AMULET asynchronous ARM Processors.
