Abstract: PURPOSE: A FPGA(Field Programmable Gate Array) having a RTBR DPL(Run Time Block Reconfigurable Data Path Logic) is provided to have the excellent efficiency by optimally sharing with a CFB(Configurable Function Block) and the RTBR DPL. CONSTITUTION: A combination operator comprises a 4bit multiplier(41) and the first and the second adder/subtracter(42,43). The 4bit multiplier(41) sums partially input data. The first adder/subtracter(42) sums the rest ply. The second adder/subtracter(43) adds/subtracts. A RTBR DPL comprises the first multiplexer(45), two registers(44), second multiplexers(46) and many configuration memories. The first multiplexer(45) selects the multiplication or the addition/subtraction by connecting with the multiplier(41) and the second adder/subtracter(43). The registers(44) are programmable as a latch or a flipflop by connecting with the first multiplexer(45) and the first adder/subtracter(42). One second multiplexers(46) select an output of the register(44) and the first multiplexer(45). The other second multiplexer(46) selects an output of the register(44) and the first adder/subtracter(42). The configurable memories decide the operation and the selection.
Abstract translation: 目的:提供具有RTBR DPL(运行时间块可重配置数据路径逻辑)的FPGA(现场可编程门阵列),通过与CFB(可配置功能块)和RTBR DPL进行最佳共享,具有极好的效率。 构成:组合运算符包括4位乘法器(41)和第一和第二加法器/减法器(42,43)。 4位乘法器(41)将部分输入数据相加。 第一加法器/减法器(42)对其余的层进行求和。 第二加法器/减法器(43)加/减。 RTBR DPL包括第一多路复用器(45),两个寄存器(44),第二多路复用器(46)和许多配置存储器。 第一多路复用器(45)通过与乘法器(41)和第二加法器/减法器(43)连接来选择乘法或加法/减法。 通过与第一多路复用器(45)和第一加法器/减法器(42)连接,寄存器(44)可编程为锁存器或触发器。 一个第二复用器(46)选择寄存器(44)和第一多路复用器(45)的输出。 另一第二多路复用器(46)选择寄存器(44)和第一加法器/减法器(42)的输出。 可配置存储器决定操作和选择。
