Description: First, the CPU must make access memory to fetch the instruction. The
instruction contains the address of the data we want to load. During the execute
phase accesses memory to load the data value located at that address for a total

Description: 用VHDL语言设计了一个含10条指令的RISC处理器。假定主存可以在一个始终周期内完成依次读写操作且和CPU同步，系统使用一个主存单元。处理器指令字长16位，包含8个通用寄存器，1个16位的指令寄存器和一个16位的程序记数器。处理器的地址总线宽度16位。数据总线宽度16位，取指和数据访问均在一跳蝻数据总线。处理器支持包含LDA，STA，MOV，MVI，ADD，SUB，AND，OR，JZ，JMP十条指令。其中仅有LDA和STA是访存指令。-VHDL language design with a RISC processor with 10 instruction. Assume that main memory can be completed in one cycle is always followed and the CPU read and write operations and the synchronization system uses a main memory unit. 16-bit instruction word processor, including 8 general purpose registers, a 16-bit instruction register and a 16-bit program counter. Processor' s address bus width 16 bits. 16-bit data bus width, fetch and data access are in the hop hoppers data bus. Processor support includes LDA, STA, MOV, MVI, ADD, SUB, AND, OR, JZ, JMP ten instructions. LDA and STA is the only one memory access instructions. Platform: |

Description: 1. RISC工作每执行一条指令需要八个时钟周期。RISC的复位和启动通过rst控制，rst高电平有效。Rst为低时，第一个fetch到达时CPU开始工作从Rom的000处开始读取指令，前三个周期用于读指令。
在对总线进行读取操作时，第3.5个周期处，存储器或端口地址就输出到地址总线上，第4--6个时钟周期，读信号rd有效，读取数据到总线，逻辑运算。第7个时钟周期，rd无效，第7.5个时钟地址输出PC地址，为下一个指令做好准备
对总线写操作时，在第3.5个时钟周期处，建立写的地址，第4个时钟周期输出数据，第5个时钟周期输出写信号。至第6个时钟结束，第7.5时钟地址输出PC地址，为下一个指令周期做好准备。
2. 操作过程：新建工程，编译compile all，然后仿真，在wave窗口加入要观察的信号，然后run –all，结束时完成test1的测试，重复两次run –all完成test2，test3的波形仿真。
-1. RISC work every eight clock cycles to execute an instruction needs. RISC reset and start by rst control, rst active high. Rst is low, the first CPUs fetch arrives starting from Rom s 000 start reading instruction, the first three cycles for reading instruction.
When the read operation is performed on the bus, at 3.5 cycles, memory, or port address output to the address bus, 4- 6 clock cycles, and the read signal rd, read data to the bus, a logic operation. 7 clock cycles, rd invalid, 7.5 PC clock address output address, ready for the next instruction
The write operation on the bus, in Section 3.5 of the clock cycle, to establish a write address, and four clock cycles and output data, the fifth clock cycle output write signal. To the end of the six clock the 7.5 clock address output PC address, ready for the next instruction cycle.
Operation: new construction, the compiler compile all, and simulation, join in the wave window to observe the signal, then the run-all completed by the Platform: |

Description: My file is about Fetch and Executive stages of processing. The processor contains a single data register, called the accumulator (AC). Both instructions and data are 16 bits long, and memory is organized as a sequence of 16-bit words. The instruction format provides 4 bits for the opcode,allowing as many as 24 16 different opcodes (represented by a single hexadecimal3 digit). The opcode defines the operation the processor is to perform.With the remaining 12 bits of the instruction format,up to 212 4096 (4 K) words of memory (denoted by three hexadecimal digits) can be directly addressed.
