What is SIMD? SIMD (Single Instruction, Multiple Data) refers to a computational model where a single instruction operates on multiple data points in parallel. Instead of processing data sequentially, SIMD enables parallel operations using wide registers, improving speed for tasks involving large datasets. Key Features of WebAssembly SIMD WebAssembly SIMD Instructions WebAssembly SIMD provides a … Read more

Key Concepts of Conditionals in WebAssembly Syntax of WebAssembly Conditionals Here is a basic syntax example for a conditional block in WebAssembly: (if (condition) (then ;; Code to execute if condition is true ) (else ;; Code to execute if condition is false )) Example 1: Basic Conditional Statement This example demonstrates a simple conditional … Read more

WebAssembly does not have direct equivalents to the traditional break and continue keywords found in high-level languages, its branch instructions (br and br_if) provide similar functionality. This guide explains how these branch instructions are used to simulate break and continue behavior in WebAssembly loops. Key Concepts In WebAssembly: Simulating Break in WebAssembly To exit a … Read more

What are Loops in WebAssembly? Loops in WebAssembly allow a sequence of instructions to be executed multiple times. WebAssembly loops are implemented using the following key constructs: Unlike higher-level languages, WebAssembly loops do not include predefined while or for syntax. Instead, they use a stack-based approach for managing flow control. Structure of a WebAssembly Loop … Read more

What is Control Flow in WebAssembly? In WebAssembly, control flow refers to the mechanisms that dictate the execution order of instructions. These mechanisms include: WebAssembly uses stack-based execution for control flow, where values are pushed to or popped from a stack during instruction processing. Key Control Flow Constructs in WebAssembly 1. Blocks (block) A block … Read more

What is WebAssembly Shared Memory? Shared memory in WebAssembly allows multiple threads to access the same memory buffer simultaneously. It is based on the SharedArrayBuffer object in JavaScript, which facilitates communication and synchronization between WebAssembly threads and the main JavaScript thread. Key Features: How WebAssembly Shared Memory Works To use shared memory in WebAssembly, a … Read more

What is WebAssembly Linear Memory? In WebAssembly, linear memory is a contiguous block of memory used by a module. It is designed to store data, such as variables, arrays and objects, in binary format. This memory model is managed by the WebAssembly runtime and is accessible to both WebAssembly and JavaScript. Key Features: Declaring and … Read more

What Are Typed Arrays in WebAssembly? Typed Arrays are arrays that allow you to work with binary data in a specific format, such as 8-bit integers or 32-bit floating point numbers. These arrays are important because WebAssembly works with raw binary data and memory and typed arrays help organize and manage that data efficiently. Why … Read more

What Are Arrays and Buffers in WebAssembly? Key Concepts How Arrays Work in WebAssembly Example 1: Basic Array in WebAssembly WebAssembly Code (WAT): (module (memory (export “memory”) 1) ;; Define 1 page (64 KiB) of memory (func $sumArray (param i32 i32) (result i32) (local $sum i32) (local $i i32) (loop $loop local.get $i local.get 1 … Read more

Key Concepts of Data Passing in WebAssembly Types of Data Passing in WebAssembly Example 1: Passing Primitive Values WebAssembly Code (in .wat format): (module (func $add (param i32 i32) (result i32) local.get 0 local.get 1 i32.add ) (export “add” (func $add))) JavaScript Code: (async () => { const response = await fetch(‘module.wasm’); const buffer = … Read more
