Managed multicores) that results in efficient code management execution on the local scratchpad memory. ...
As we scale the number of cores in a multicore processor, scaling the memory hierarchy is a major challenge. Software Managed Multicore (SMM) architectures are one of the promising solutions. ...
The first step in code management is to assign some space in the local scratchpad memory for managing code. ...
