MIPS ALU (练习)

在行为VHDL中（使用2个并发进程）描述MIPS ALU，该MIPS ALU支持带符号算术和最多16个操作/功能，如图1所示。ALU具有以下接口： • Generics - ALU data bits (n_bits_alu with default value of 32 bits) - Total number of supported operations/functions (n_functions_alu with default value of 16 functions) • Inputs - First input operand (A -> n_bits_alu bits = 32 bits) - Second input operand (B -> n_bits_alu bits = 32 bits) - ALU control (ALUControl -> [log2 (n_functions_alu)] bits) • Outputs - Result output operand (C -> n_bits_alu bits = 32 bits) - Zero flag (zero -> 1 bit) - Overflow flag (overflow -> 1 bit) • In Vivado - Create a blank project - Add design and simulation source files - Run behavioral simulation - Your waveform configuration should be identical to the provided waveform snapshot, see Figure 2.
