1. Implementing Shared Compilation Cache Across Multiple Runtime Environments in the WASM Virtual Machine

We have successfully implemented a shared compilation cache for multiple runtime environments. This feature allows different WASM modules to reuse already compiled code during loading, thereby reducing memory usage and startup time. A unified cache management mechanism has been adopted to ensure that compilation results can be effectively recognized and invoked across different runtimes. Multiple performance tests have been conducted, showing that the implementation of the shared cache has reduced average startup time by 30%.

2. Enabling String Input and Output in WebAssembly Functions within the WASM Virtual Machine

The ability to pass strings is a crucial aspect of WebAssembly’s interaction with external environments, and supporting string input and output will greatly enhance the flexibility and usability of WASM modules.

We have successfully implemented the functionality to pass strings in and out of WASM functions. This feature allows developers to handle text data within WASM modules, increasing the practicality of the modules.

UTF-8 encoding has been used to process strings, ensuring compatibility with external languages such as JavaScript. We have also implemented a corresponding memory management mechanism to prevent memory leaks and overflow issues.
