| New 32-bit-MCU/DSP Architecture with highest data throughput and low power consumption |

According the market demands… It looks like performance is never sufficient and so an relatively simple approach to increase is, to increase the overall system clock frequency until the requirements are achieved. Never a advantage without a disadvantage, and so the power consumption increases quite linear with the frequency which can lead to limits of battery driven systems. With the new AVR32 Family ATMEL takes an other approach. Not only driven by process technology the performance and data throughput is increased but also with new architecture elements and optimized structures. During development of the architecture there was an extensive exchange also with the compiler manufacturer IAR. |

Die AVR32 Architecture The AVR32 32-bit RISC processor core was designed to do more processing per clock cycle so the same throughput can be achieved at a lower clock frequency. A JTAG Debug / Programming Interface and an OCD-System (On-Chip-Debug) supports efficiently programming and debugging of the system. Instruction- and Data-cache do increase the performance. The Memory Management Unit (MMU) allows porting Operation System like Linux. A tightly coupled Bus for fast access to the embedded pixel Coprocessor. The AVR32 core achieves higher data throughput by avoiding non-productive processor cycles. This is achieved for example, by reduction of load/store cycles, maximal usage of internal resources, zero penalty branches and increasing the hit rates within the cache memory. |

Benchmarking by EEMBC The independent Embedded Microprocessor Benchmark Consortium EEMBC is doing benchmark tests on processor architectures with various algorithm by using non-optimized compiled codes. The AVR32 achieves higher performance per MHz than many other major high-end 32-bit standard MCU cores because of special features inside its architecture. |

AVR32 Roadmap With the availabilty of the AT32AP7000, a full equipped family member, it is possible to start any development and evalution. All other products will be available end of 2006 which allows optimal part selection for an application at optimal cost. The AP700x devices are only a small portion of planned, future members. ATMEL is currently developing solutions with additional peripherals for custom specific application. |
