WasmEdge - SSVM 0.2.0

Published by hydai almost 5 years ago

Features:

Native Cost Metering
- SSVM provides CostTab for each instruction including Wasm, Wasi, Ewasm.
- With this feature, users can set the cost limit for measuring the execution cost.
Built-in performance timer
- TimeRecord collects execution time for the performance analysis.
- TimeRecord supports multiple timers.
- SSVM also provides Wasi timer API for developers to customize TimeRecord.
Multiple Virtual Machine Environment
- Wasm mode: Support general Wasm program.
- Wasi mode: In addition to Wasm mode, this mode contains basic Wasi functions like print.
- QITC mode: In addition to Wasi mode, this mode is designed for ONNC runtime to execute AI models by leveraging Qualcomm Hexagon SDK.
- Ewasm mode: In addition to Wasm mode, this mode is designed for Ethereum flavor WebAssembly.
Start functions enhancement
- Support start function assignment. This makes users invoke an exported function with a given function name.
- Support start function arguments and return value. This makes users can insert arguments and retrieve result after execution.
Simple statistics output
- Dump total execution time and instruction per second for benchmarking.
- Print used gas costs for Ewasm mode.
- Print storage and return values.

Tools:

Sub-project Qualcomm Innovate in Taiwan Challenge(a.k.a QITC) 2019
- SSVM-QITC enables AI model execution by integrating ONNC runtime and Qualcomm Hexagon SDK.
- With this tool, users can run AI model inference within a WebAssembly Virtual Machine.
Sub-project Ethereum
- SSVM-EVM integrates the Ethereum Environment Interface(EEI) as a WebAssembly extension.
- With this tool, users can run blockchain applications, which are compiled into Ewasm bytecodes.
Sub-project General Wasi Support
- SSVM tool provides basic Wasi functions support, such as print function.
