Scratch-pad memory allocation without compiler support for java applications

ABSTRACT This paper presents the first scratch-pad memory allocation scheme that requires no compiler support for interpreted-language based applications. A scratch-pad memory (SPM) is a fast compiler-managed SRAM that replaces the hardware-managed cache. Its uses are motivated by its better realtime guarantees as compared to cache and by its significantly lower overheads in energy consumption, area and access time. Interpreted languages are languages such as Java that are interpreted by a runtime environment instead of being executed directly on hardware. All existing memory allocation schemes for SPM require compiler analysis to develop the allocation strategy. Specifically, existing allocation schemes for Java-based applications determine the allocations at compile-time. They then annotate the Java bytecodes with these allocation decisions for the Java Virtual Machine (JVM) to implement the actual allocation at runtime. These existing allocation schemes tie the resulting bytecode to...
