System and method for allowing embedded devices, even with a limited amount of CPU power and limited memory, to run code more efficiently by eliminating all or most of the runtime checks, while retaining the benefits of runtime checks. The runtime checks may be moved or duplicated to an outside application running on a remote computer. The outside application can prepare the runtime checks for execution at the embedded system. The embedded system may receive pre-validated code and store it inside custom cache for later execution using a check-less, or check-limited, runtime on the embedded device.
