Course: Computer Architecture (CARC103) — Content Analysis Weeks 1–11

Student: [Name] | Word count: ~1000

Introduction (≈100 words)

The purpose of this reflective content analysis is to synthesise and interpret core theoretical concepts presented across weeks 1–11 of the Computer Architecture unit. The review focuses on hardware fundamentals, system organization, operating system principles, data storage and manipulation, device and process management, scheduling, networking, and considerations for enterprise integration platforms. Each weekly entry summarises key ideas, defines essential terms, interprets the most relevant information for practical application, and states personal learning outcomes. This structured reflection supports deeper comprehension of how architectural decisions, operating system mechanisms and integration strategies impact system performance, reliability and scalability (Hennessy & Patterson 2019; Tanenbaum & Bos 2015).

Background (≈100 words)

This unit combines classical computer architecture theory with contemporary operating systems and networking concepts. Foundational knowledge derives from established texts and landmark papers which explain CPU design, instruction sets, memory hierarchies, I/O systems and distributed storage (Stallings 2018; Silberschatz, Galvin & Gagne 2018). Modern approaches to large-scale data handling and platform choice (e.g. MapReduce, Google File System) are considered to bridge theory and practice for enterprise contexts (Ghemawat, Gobioff & Leung 2003; Dean & Ghemawat 2004). The background anchors weekly analyses in accepted academic frameworks while highlighting design trade-offs relevant for system architects and administrators (Hennessy & Patterson 2019).

Week 1 — Computer Architecture Fundamentals

Theoretical Discussion: Core topics: von Neumann model, CPU components (ALU, control unit, registers), instruction set architecture (ISA) and performance metrics. Definitions: ISA as the programmer-visible machine interface (Hennessy & Patterson 2019). Interpretation: Understanding the ISA and microarchitecture separation clarifies how software portability and hardware performance trade-offs arise. Designers optimise pipelines, caches and clock rates based on workload characteristics (Stallings 2018). Outcome: I learned to evaluate architecture choices by linking ISA features to expected application demands and to prioritise metrics such as IPC and latency when assessing designs (Hennessy & Patterson 2019).

Week 2 — Processor Design and Pipelining

Theoretical Discussion: Topics: instruction pipelining, hazards (data, control, structural), superscalar execution and out-of-order processing. Definitions: pipeline hazards as conditions that prevent the next instruction following the pipeline stages (Stallings 2018). Interpretation: Pipeline complexity increases IPC but introduces hazard mitigation overheads (stalling, forwarding, branch prediction). The balance between hardware complexity and performance gains is crucial. Outcome: I appreciate trade-offs in pipeline depth and the rationale for branch prediction and speculative execution to maintain throughput (Hennessy & Patterson 2019).

Week 3 — Memory Hierarchy and Caching

Theoretical Discussion: Topics: cache levels, hit/miss rates, locality of reference, virtual memory and page tables. Definitions: temporal and spatial locality underpin caching effectiveness (Stallings 2018). Interpretation: Memory hierarchy design (L1–L3, DRAM, secondary storage) directly impacts application performance; software must be cache-aware for optimal throughput. Virtual memory provides abstraction but costs in TLB misses and page faults (Silberschatz et al. 2018). Outcome: I learned to reason about cache size, associativity and replacement policies as levers for improving observed runtime behavior.

Week 4 — I/O and Device Management

Theoretical Discussion: Topics: device controllers, DMA, interrupt handling and drivers. Definitions: DMA enables peripheral devices to transfer data to memory without CPU intervention (Silberschatz et al. 2018). Interpretation: Efficient I/O paths reduce CPU overhead and bottlenecks; interrupt-driven designs and DMA accelerate throughput for high-volume devices. Outcome: I learned to assess system I/O performance by examining bus architectures and driver-level optimisations.

Week 5 — Operating System Concepts

Theoretical Discussion: Topics: kernel structure (monolithic vs microkernel), system calls, process and thread abstractions. Definitions: a process is an executing program with its own memory context (Tanenbaum & Bos 2015). Interpretation: OS design influences security, modularity and fault tolerance; microkernels reduce kernel surface but may increase IPC costs. Outcome: I gained clarity on selecting kernel models based on the need for reliability versus performance (Silberschatz et al. 2018).

Week 6 — Process Management and Scheduling

Theoretical Discussion: Topics: scheduling algorithms (FCFS, SJF, RR, priority, multi-level feedback queues) and synchronization primitives. Definitions: preemptive scheduling allows the OS to interrupt running processes to enforce fairness (Tanenbaum & Bos 2015). Interpretation: Scheduling choices affect responsiveness and throughput; synchronization (locks, semaphores) is essential to avoid race conditions at cost of potential blocking. Outcome: I practiced mapping workload types to scheduling policies to meet latency or throughput goals.

Week 7 — Concurrency and Deadlock

Theoretical Discussion: Topics: concurrency models, critical sections, deadlock conditions and avoidance/detection strategies. Definitions: deadlock requires mutual exclusion, hold-and-wait, no preemption and circular wait (Silberschatz et al. 2018). Interpretation: Preventing deadlocks often requires trade-offs in resource utilisation; detection plus recovery can be pragmatic in dynamic environments. Outcome: I learned formal techniques to reason about safe resource allocation strategies.

Week 8 — File Systems and Storage

Theoretical Discussion: Topics: file system organisation, journalling, distributed file systems. Definitions: distributed file systems provide location transparency and replication for reliability (Ghemawat, Gobioff & Leung 2003). Interpretation: For large datasets, design choices (replication, consistency models) determine performance and availability. Outcome: I learned how designs like GFS trade strong consistency for high throughput and fault tolerance in large clusters (Ghemawat et al. 2003).

Week 9 — Data Processing at Scale

Theoretical Discussion: Topics: batch processing, MapReduce paradigm and data locality. Definitions: MapReduce abstracts parallel data processing into map and reduce phases (Dean & Ghemawat 2004). Interpretation: Data locality and fault-tolerant task scheduling are critical to scale; programming models that hide parallelism simplify development. Outcome: I understood the value of decomposable workloads and how distributed frameworks optimise resource use (Dean & Ghemawat 2004).

Week 10 — Networks and Communications

Theoretical Discussion: Topics: OSI/TCP-IP models, routing, congestion control and protocols. Definitions: TCP provides reliable, ordered delivery; UDP provides connectionless datagrams (Kurose & Ross 2017). Interpretation: Network design affects latency and throughput across distributed systems; protocol selection should match application tolerance for loss and delay. Outcome: I learned to evaluate transport and routing protocols for different application classes (Kurose & Ross 2017; Comer 2018).

Week 11 — Enterprise Integration and Platform Selection

Theoretical Discussion: Topics: integration patterns, middleware, cloud platform criteria (scalability, manageability, cost). Definitions: integration patterns describe messaging and orchestration strategies (Hohpe & Woolf 2003). Interpretation: Platform selection must weigh technical fit (APIs, data models), operational concerns and vendor lock-in. Cloud definitions and service models (IaaS, PaaS, SaaS) inform decision-making (Mell & Grance 2011). Outcome: I learned to apply architectural criteria and integration patterns to recommend platforms that meet enterprise non-functional requirements.

Conclusion (≈50 words)

This reflective analysis synthesised core architectural, OS, storage and networking theories across weeks 1–11 and linked them to practical design choices. I now better evaluate trade-offs between performance, scalability and reliability and can recommend informed architecture and platform choices for real-world systems (Hennessy & Patterson 2019; Tanenbaum & Bos 2015).
