bpu

GPU and BPU are redunded ( 3:2 for GPU and 2:1 for BPU ).

GPU和BPU为冗余配置 ( GPU为3:2,BPU为2:1 ).

Results Mucosal blood flow of fundus and antrum in rabbits with PHT group was ( 73.44 ± 25.47) BPU and ( 97. 85 ± 15.05) BPU respectively;

结果PHT组胃底、胃窦的粘膜血流量分别为（73.44±25.47）BPU.（97.85±15.05）BPU；

The BPU use static and dynamic branch prediction algorithm optionally, meanwhile we use the BTIC to accelerate the speed of branch processing.

其中分支处理单元可支持静态和动态分支预测算法，同时该单元中利用分支目标地址缓冲区（BTIC）加快分支处理速度。取指策略主要采用适合于龙腾R2的多取指低频度方法。

Complete the front-end architecture of the "Longtium R2" fix point pipeline, include BPU and instruction fetching unit.

完成龙腾R2处理器中包括分支处理单元和取指单元在内的流水线前端组织结构的详细设计。
