Basic concepts of computer architecture and design
Instruction set architecture
The instruction set architecture (ISA) is the interface between the hardware and software of a computer system. It defines the set of instructions that the processor can execute, as well as the format, operands, addressing modes, registers, flags, exceptions, interrupts, and system calls associated with them. The ISA determines how the software can control the hardware and how the hardware can respond to the software.
Types of instruction sets
There are two main types of instruction sets: reduced instruction set computing (RISC) and complex instruction set computing (CISC). RISC instruction sets have fewer and simpler instructions, which can be executed faster and more efficiently by the processor. CISC instruction sets have more and complex instructions, which can perform more operations in a single instruction, but require more cycles and resources to execute. Both types of instruction sets have their advantages and disadvantages, depending on the application and the implementation.
Examples of instruction sets
Some examples of popular instruction sets are: x86, which is a CISC instruction set used by Intel and AMD processors in personal computers; ARM, which is a RISC instruction set used by many processors in mobile devices; MIPS, which is another RISC instruction set used by many processors in embedded systems; and RISC-V, which is an open-source RISC instruction set that aims to be a standard for various domains.
Computer organization is the way the hardware components of a computer system are arranged and connected to perform the functions specified by the ISA. It involves the design and implementation of the processor, memory, input/output devices, and interconnection networks. Computer organization also affects the performance, power, reliability, security, and scalability of the system.
Components of a computer system
The main components of a computer system are: the processor, which executes the instructions and performs the computations; the memory, which stores the data and instructions; the input/output devices, which allow the system to interact with the external world; and the interconnection networks, which enable the communication and data transfer among the components. Each component can have different levels of hierarchy, complexity, and functionality.
Performance metrics and benchmarks
The performance of a computer system can be measured by various metrics, such as speed, throughput, latency, bandwidth, efficiency, utilization, and quality of service. These metrics can be evaluated by using different benchmarks, which are standardized tests or programs that simulate typical or specific workloads for the system. Some examples of common benchmarks are: SPEC CPU, which measures the processor performance for general-purpose applications; LINPACK, which measures the processor performance for scientific computations; HPL-AI, which measures the processor performance for artificial intelligence applications; STREAM, which measures the memory bandwidth for simple operations; and I/Ozone, which measures the input/output performance for various devices.
Computer arithmetic is the branch of computer science that deals with the representation and manipulation of numerical data in a computer system. It involves choosing the appropriate formats, algorithms, and hardware units to perform arithmetic operations on integers, fractions, decimals, complex numbers, vectors, matrices, polynomials, and other mathematical objects.
Binary representation and operations
Binary representation is the way numerical data is stored and encoded in a computer system using only two symbols: 0 and 1. These symbols are called bits (binary digits), and they can be grouped into larger units called bytes (8 bits), words (16 bits), double words (32 bits), or quad words (64 bits). Binary representation allows the computer to perform arithmetic operations on numerical data using simple logic gates, such as AND, OR, NOT, XOR, NAND, NOR, etc.
Floating-point representation and operations
Floating-point representation is another way numerical data is stored and encoded in a computer system using a fixed number of bits. It allows the computer to represent real numbers with fractional parts and varying orders of magnitude. Floating-point representation consists of three parts: sign bit (S), exponent (E), and mantissa (M). The value of a floating-point number is given by: (-1)^S * M * 2^E. Floating-point representation allows the computer to perform arithmetic operations on real numbers using specialized hardware units called floating-point units (FPUs).
Advanced topics of computer architecture and design
Pipelining is a technique that improves the performance of a processor by dividing an instruction into several stages and executing multiple instructions concurrently in different stages. Each stage performs a specific function on an instruction, such as fetch (F), decode (D), execute (E), memory access (M), or write back (W). Pipelining increases the throughput (number of instructions completed per unit time) of the processor without increasing its clock frequency.
Principles of pipelining
The principles of pipelining are: balance (the workload among the stages should be evenly distributed), locality (the data required by each stage should be available nearby), parallelism (the stages should operate independently without interfering with each other), and simplicity (the stages should be simple enough to minimize delays and errors).
Hazards and solutions
Pipelining can encounter some problems that reduce its performance or correctness. These problems are called hazards, and they can be classified into three types: data hazards (when an instruction depends on the result of a previous instruction that has not been completed yet), control hazards (when an instruction changes the flow of execution and causes the pipeline to fetch the wrong instructions), and structural hazards (when two instructions require the same hardware resource at the same time). There are various solutions to deal with these hazards, such as forwarding (passing the result of a previous instruction to a later instruction without waiting for the write back stage), stalling (pausing the pipeline until the hazard is resolved), branch prediction (guessing the outcome of a branch instruction and fetching the instructions accordingly), and dynamic scheduling (reordering the instructions to avoid dependencies and conflicts).
Memory hierarchy is the way the memory components of a computer system are organized and accessed to achieve high performance and low cost. It involves using multiple levels of memory with different sizes, speeds, costs, and technologies, such as registers, cache, main memory, disk, and tape. The memory hierarchy follows the principle of locality, which states that most of the time, the processor accesses only a small portion of the data and instructions that are nearby in space or time.
Cache memory is a small and fast memory that stores a copy of the frequently accessed data and instructions from the main memory. It reduces the average access time and bandwidth requirements of the processor. Cache memory can have different levels (L1, L2, L3, etc.), sizes, organizations (direct-mapped, set-associative, fully-associative, etc.), and policies (write-through, write-back, write-allocate, write-no-allocate, etc.). Cache memory can also suffer from misses (when the requested data or instruction is not found in the cache), which can be caused by compulsory (the first access to a block), capacity (the cache is too small to hold all the blocks), or conflict (two blocks map to the same location) reasons.
Virtual memory is a technique that allows the computer to use disk space as an extension of the main memory. It enables the computer to run programs that are larger than the available physical memory. It also provides protection and isolation among different processes and users. Virtual memory works by dividing the address space of a program into fixed-size units called pages, and mapping them to variable-size units of physical memory called frames. The mapping information is stored in a data structure called page table. Virtual memory can also cause page faults (when the requested page is not in the main memory), which require transferring the page from disk to main memory.
Parallel processing is a technique that improves the performance of a computer system by using multiple processors or cores to execute multiple instructions or tasks simultaneously. It exploits the inherent parallelism in many applications, such as scientific computing, image processing, artificial intelligence, etc. Parallel processing can also increase the reliability, availability, and scalability of the system.
Types of parallelism
There are two main types of parallelism: instruction-level parallelism (ILP) and thread-level parallelism (TLP). ILP refers to executing multiple instructions from a single instruction stream in parallel within a processor or core. ILP can be achieved by using techniques such as pipelining, superscalar execution, out-of-order execution, speculative execution, etc. TLP refers to executing multiple instruction streams from multiple tasks or threads in parallel across multiple processors or cores. TLP can be achieved by using techniques such as multiprocessing, multithreading, multicore processing, etc.
Challenges and opportunities
Parallel processing faces many challenges and opportunities in terms of design and implementation. Some of these are: synchronization (coordinating the actions and data access among parallel processors or threads), communication (transferring data and messages among parallel processors or threads), load balancing (distributing the workload evenly among parallel processors or threads), scalability (maintaining or improving performance as more processors or threads are added), power consumption (reducing or optimizing energy usage by parallel processors or threads), fault tolerance (handling errors or failures by parallel processors or threads), and programming models (providing easy and efficient ways to express and execute parallel programs).
