pulsar

Pulsar is a programming language for building hardware accelerators. In what exactly? I'm not sure yet.

As of right now, I'm using Swift's syntax for that nice syntax highlighting:

func increment(x: Int) -> Int {
    return x + 1
}
func main() {
    let input = [1, 2, 3, 4]
    let output = map<1>(increment, input)
}

The calyx backend is tested e2e via verilator, a hardware simulation tool.

Crates

• pulsar-lang: Compiler driver
• pulsar-utils: Utilities for the pulsar-* crates
• pulsar-frontend: Parser/AST and type checking
• pulsar-ir: Structured and unstructured IR
• pulsar-backend: Target emission, e.g., Verilog (via calyx)
