    • A sliding-window, block-based Branch Target Address Cache (BTAC) comprises a plurality of entries, each entry associated with a block of instructions containing at least one branch instruction having been evaluated taken, and having a tag associated with the address of the first instruction in the block. The blocks each correspond to a group of instructions fetched from memory, such as an I-cache. Where a branch instruction is included in two or more fetch groups, it is also included in two or more instruction blocks associated with BTAC entries. The sliding-window, block-based BTAC allows for storing the Branch Target Address (BTA) of two or more taken branch instructions that fall in the same instruction block, without providing for multiple BTA storage space in each BTAC entry, by storing BTAC entries associated with different instruction blocks, each containing at least one of the taken branch instructions.
    • 滑动窗口,基于块的分支目标地址高速缓存(BTAC)包括多个条目,每个条目与包含已被评估的至少一个分支指令的指令块相关联,并且具有与该地址相关联的标签 第一个指令在块中。 这些块各自对应于从存储器获取的一组指令,例如I缓存。 在两个或更多个取出组中包含分支指令的情况下,还包括在与BTAC条目相关联的两个或多个指令块中。 滑动窗口,基于块的BTAC允许存储落在同一指令块中的两个或更多个采取的分支指令的分支目标地址(BTA),而不需要在每个BTAC条目中提供多个BTA存储空间,通过存储BTAC条目 与不同的指令块相关联,每个指令块包含至少一个采取的分支指令。
