Explore the fundamental concepts of computer systems through this comprehensive course covering both structural relationships in computer organization and functional behavior in computer architecture. Designed for college and university students as well as exam aspirants, particularly those preparing for GATE, this course provides detailed explanations and numerical problem-solving from previous year questions across all major topics. Master memory hierarchy and interfacing concepts including cache memory implementations through direct mapping, associative mapping, and set associative mapping, along with secondary memory systems. Delve into computer organization fundamentals covering machine instructions, addressing modes, ALU operations, data-path design, and both hard-wired and microprogrammed control units. Understand I/O interfacing techniques including isolated and memory mapped I/O, and various transmission modes such as programmed, interrupt-driven, and DMA approaches. Learn instruction pipelining concepts including hazards, branch prediction, and speculative execution. Build a strong foundation in number systems covering different bases, complementary number systems, subtraction using addition principles, signed number representation with ranges and overflow concepts, binary codes with error detection and correction capabilities, IEEE floating point standards for single and double precision, and advanced topics like Booth's multiplication algorithm and both restoring and non-restoring binary division methods.
