This paper describes design decisions for JOP, a Java Optimized Processor, implemented in an FPGA. FPGA density-price relationship makes it now possible to consider them not only for prototyping of processor designs but also as final implementation technology. However, using an FPGA as target platform for a processor different constraints influence the CPU architecture. Digital building blocks ...

Java is still not a common language for embedded systems. It posses language features, like thread support, that can improve embedded system development, but common implementations as interpreter or just-in-time compiler are not practical. JOP is a hardware implementation of the Java Virtual Machine with focus on real-time applications. This paper describes the architecture of JOP and proposes ...

In this paper, we will present the evaluation results for a Java processor, with respect to size and performance. The Java Optimized Processor (JOP) is an implementation of the Java virtual machine (JVM) in a low-cost FPGA. JOP is the smallest hardware realization of the JVM available to date. Due to the efficient implementation of the stack architecture, JOP is also smaller than a comparable R...

Alexandria, VA. – The Journal of Oncology Practice (JOP) today will publish three articles being presented in oral sessions at ASCO’s 2017 Quality Care Symposium (QCS) in Orlando, FL. In its aim to provide top resources on clinical and administrative management for the oncology field, JOP is extending its publishing territory to work with researchers and publish the latest findings in conjuncti...

Modern software deployment process produces that is uniform and hence vulnerable to large-scale code-reuse attacks, such as Jump-Oriented Programming (JOP) attacks. Compiler-based diversification improves the resilience of systems by automatically generating different assembly code versions a given program. Existing techniques are efficient but do not have precise control over quality generated...

Architectural advancements in modern processor designs increase average performance with features such as pipelines, caches, branch prediction, and out-of-order execution. However, these features complicate worst-case execution time analysis and lead to very conservative estimates. JOP (Java Optimized Processor) tackles this problem from the architectural perspective – by introducing a processo...

Java, a popular programming language on desktop systems, is rarely used in embedded systems. Some features of Java, like thread support in the language, could greatly simplify development of embedded systems, but the common implementations of the JVM (Java Virtual Machine), as interpreter or just-in-time compiler, are not practical. This paper describes an alternative approach: JOP (a Java Opti...

In this paper, we propose a solution for a worst-case execution time (WCET) analyzable Java system: a combination of a time predictable Java processor and a tool that performsWCET analysis at Java bytecode level. We present a Java processor, called JOP, designed for time-predictable execution of real-time tasks. The execution time of bytecodes, the instructions of the Java virtual machine, is k...
