Abstract
A computing device is provided and includes a memory module, a sweep engine, a root snapshot module, and a trace engine. The memory module has a memory implemented as at least one hardware circuit. The memory module uses a dual-ported memory configuration. The sweep engine includes a stack pointer. The sweep engine is configured to send a garbage collection signal if the stack pointer falls below a specified level. The sweep engine is in communication with the memory module to reclaim memory. The root snapshot engine is configured to take a snapshot of roots from at least one mutator if the garbage collection signal is received from the sweep engine. The trace engine receives roots from the root snapshot engine and is in communication with the memory module to receive data.
