The best software is custom hardware.

BoolSi generates the right chip for your application.

Search visualization tracing paths across a grid of cells

Push-button hardware acceleration,
zero chip design experience needed

BoolSi was created to compile your software into hardware, not just the CPU. Mark a hotspot (or two) in your embedded application, and BoolSi synthesizes it into custom digital logic, a co-processor designed for your specific application needs. The platform also handles the deployment steps: mapping API calls to the function signature, updating the BSP, and producing the hardware bitstream. A function that used to bottleneck your application now runs as a custom co-processor, generated, verified, and deployed at the click of a button.

A control-flow hotspot running slowly on a CPU, the block synthesized into hardware, then running far faster
A hotspot in your program, synthesized into a hardware agent.
The same logic, off the CPU and into silicon.
01

Hardware agents

A hot C or C++ function, compiled into a custom silicon accelerator.

02

10-100× faster

Hotspots leave the CPU for purpose-built logic and run orders of magnitude faster.

03

A compilation artifact

Generated hardware is a build output: no HDL, no Git diff, no parallel codebase.

04

Push-button development

Mark a function for acceleration; the toolchain handles the rest.

05

Functionally and formally verified

Every agent is checked against your source program before it runs.

06

Built for embedded

For robotics and devices where every microsecond shows up in the product.

The same code, 63× faster.

A 10,000-line C regex library finding email addresses in a text stream, compiled gcc -O3 for an ARM Cortex-A9 baseline, then compiled to BoolSi hardware agents.

Eight agents scale near-linearly. The fabric parallelizes.

If your product is bottlenecked on a CPU or a microcontroller and you've ever wished you could just make a chip for it, get on the list.
