The scratchpad memories are widely used in embedded architectures to allow software memory management, but traditionally in general purpose projects existing applications are limited to the cache usage, because its benefits and the legacy code make the scratchpad memories unviable. This dissertation presents a transparent model for scratchpad memories for general purpose architectures, allowing its use when it is beneficial, without generating any noise to the legacy code when it is not. It is proposed a mixed approach to memory management in on-chip level providing the cache and scratchpad memory at the same time. In the experiments an improvement up to 17% in performance was observed. As a result, this dissertation presents a solution for production of a diverse environment that accommodates the efficiency demands with backward compatibility, enabling efficiently meet a wider range of applications with different requirements.
