Title

A Dynamic Scratchpad Memory Unit for Predictable Real-Time Embedded Systems

Abstract

Scratch-pad memory is a popular alternative to caches in real-time embedded systems due to its advantages in terms of timing predictability and power consumption. However, dynamic management of scratch-pad content is challenging in multitasking environments. To address this issue, this thesis proposes the design of a novel Real-Time Scratchpad Memory Unit (RSMU). The RSMU can be integrated into existing systems with minimal architectural modifications. Furthermore, scratchpad management is performed at the OS level, requiring no application changes. In conjunction with a two-level scheduling scheme, the RSMU provides strong timing guarantees to critical tasks. Demonstration and evaluation of the system design is provided on an embedded FPGA platform.
