Unfortunately, as an AI language model, I do not have access to the latest information on technology products. However, I can tell you that an FPGA (Field-Programmable Gate Array) is a type of integrated circuit that can be programmed to perform specific tasks, making it highly customizable and flexible. The number "128SRL" may refer to the specific model or configuration of the FPGA.

FPGA的SRLC32E
FPGA的SRLC32E是一种特殊的移位寄存器单元,在Xilinx FPGA芯片中被广泛使用。它是由两个SRL16E组成的,可以用于创建32位的移位寄存器。SRLC32E的地址是复用的,可以通过选择输入信号的长度来控制移位输出的长度。具体而言,SRLC32E可以实现1位到16位不等长度的移位寄存器。
此外,SRLC32E还可以与其他SRL32单元组合,以实现更大位宽的移位寄存器,如64位、96位和128位。通过使用地址信号和F7AMUX信号来切换SRL32单元,可以实现对移位寄存器的灵活控制。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

sll,srl,sra
sll、srl、sra 是移位操作指令,常用于计算机组成原理中。
- sll:逻辑左移,将二进制数的各位全部左移若干位,低位补零。
- srl:逻辑右移,将二进制数的各位全部右移若干位,高位补零。
- sra:算术右移,将二进制数的各位全部右移若干位,高位补符号位。
在汇编语言中,sll、srl、sra 对应的指令分别为 sll、srl、sra。在 C 语言中,可以用位运算符<<、>>来实现移位操作。
