The SSP: an example of high-assurance systems engineering

Transformation-Based Library Adaptation for Embedded Systems

“…java.lang and java.util). The targeted platform for adapted libraries is the SCORE processor -a jVM developed at Sandia National Laboratories [11,18].…”

“…The targeted platform is the SCORE processor [11,18]. We summarize the processor's restrictions below:…”

“…This paper takes a look at one aspect of the high-level language support problem: the adaptation of general purpose libraries with the goal of making them suitable for use in embedded applications. In particular, a transformation-based technique is described capable of automatically carrying out the majority of the activities needed to adapt Java libraries such as java.lang for use with an embedded system known as the SCORE processor [11,18], a hardware implementation of a significant subset of the Java Virtual Machine that has been developed at Sandia National Laboratories.…”

Program Transformation Using HATS 1.84

“…In particular, we will take a closer look at class loading as it relates to the Sandia Secure Processor (SSP) [22]. The SSP is a hardware implementation of a significant subset of the Java Virtual Machine whose application domain extends to embedded high consequence systems.…”

An abstract class loader for the SSP and its implementation in TL.

“…The implementation is called the Sandia Secure Processor (SSP) [11] [24] and supports a subset of Java bytecodes as its native instruction set. This paper has three objectives: (1) to informally describe the core functionality of the class loader for the SSP, (2) to demonstrate how the abstract functionality of this core class loader can be implemented using higher-order strategic programming techniques, and (3) to discuss how the correctness of the class loader can formally verified.…”
