由于传统的RISC处理器的处理能力不足以支持数字消费产品的持续发展，我们需要一种新的高性能处理器来支持多媒体应用。处理多媒体视频图像所需的性能是当前可用性能的10倍以上。在富士通，我们在软件方面提供这种更高的性能，以实现高度的灵活性。我们开发了采用新型嵌入式VLIW(超长指令字)体系结构的FR500微处理器，用于此类数字消费产品。FR500是FR-V系列的第一款产品，FR-V系列是富士通VLIW架构微处理器的通用名称。FR-V系列为开发针对各种数字消费产品而优化的新产品提供了灵活性。在本文中，我们描述了FR-V体系结构，包括我们的可变长度VLIW和指令集体系结构、推测执行控制和条件执行控制。我们还对其性能进行了评估。
Because conventional RISC processors have insufficient processing power to support the continuing development of digital consumer products, we need a new high performance processor for multimedia applications. Processing multimedia video images requires more than 10 times the currently available performance. At Fujitsu, we provide this higher performance in software to attain a high degree of flexibility. We developed the FR500 microprocessor with a novel embedded VLIW (very long instruction word) architecture for use in such digital consumer products. The FR500 is the first product in the FR-V line, Fujitsu's generic name for VLIW architecture microprocessors. The FR-V line offers the flexibility to develop new products optimized for a wide variety of digital consumer products. In this paper, we describe the FR-V architecture, which includes our variable-length VLIW and instruction set architectures, speculative execution control, and conditional execution control. We also evaluate its performance.
