Short Desc. : AU-J1000: High Performance Java Processor Core
Overview :
The AU-J1000 Java Processor Core is a Java processor core targeted at efficient high performance Java execution. Java performance is significantly faster than other software *and* hardware Java solutions due to several proprietary mechanisms that boost Java performance. For software compatibility, the Java Core can be integrated with a legacy core (such as Power PC, x86, ARM, etc.). Power management hardware ensures that only the active core consumes power
at any given time.
Features : - Hardware accelerated Java execution- 20,000/30,000 Embedded Caffeine Marks at
- 200/350 MHz (predicted)
- Peak execution rate of 4 instructions/cycle (7 bytecodes/cycle)
- Proprietary hardware accelerates common Java specific functions
- Execution of all “The Java Virtual Machine Specification” bytecodes (fourteen
- bytecodes require software assists)
- Proprietary bytecode execution for the JVM run time system (system functions)
- 5 stage RISC pipeline
- Configurable instruction cache- 32 to 8K bytecodes
- Configurable data cache- 32 to 8K bytes
- Interrupts- 16 interrupt request lines and software interrupts
- High bandwidth memory interface
- Seamless connection to Processor Memory and Bus Interface Cores from Aurora
- VLSI that provide a bus interface and memory interface
