\section{Overview} \label{overview}%------------------------------
The structure of Single cyclic MIPS CPU has been introduced in CS 11007 class lecture.
\begin{itemize}
\item{\textbf{Supported Instructions} includes \emph{sub, add, or, ori, lw, sw, lst, beq, j}, or adding \emph{addi, and, andi} for better programming experience in assembly. All these instructions can be supported without exception detecting (overflow detecting)}
\item{\textbf{All instructions work in one cycle.} For the very beginning stage, Single Cyclic CPU model is a great example to explain how CPU works.}
\item{\textbf{Consisted of Data Path, Control Unit and Memory Unit.} To illustrate the typical systematic idea of computer, we recommend you design your first CPU with two separated modules, CPath and DPath, in such coding style, both blocks can also be easily verified separately. Additionally, if more complement MIPS ISA is chosen, this structure will be high efficient to be extended.}
\item{\textbf{Chisel3 is also recommended.} Chisel is a powerful structural hardware description language, with more efficient expression for block, operation, and IO bundles compared with Verilog. However, the most significant feature of Chisel is that it can express the structure of system without detailed circuits coding. Further more, we prefer Chisel3 instead of Chisel2, which relies on verilator for verilog simulations instead of Synopsys vcs. The difference between these tow versions can be referenced here: \url{https://github.com/ucb-bar/chisel3/wiki/Chisel3-vs-Chisel2}.}
\end{itemize}

\section{System Design} \label{sysdes}%------------------------------
\subsection{System Overview}\label{sub:sysover}
Please describe your CPU system design here, Figures are recommended for detailed illustration and add the figure using latex could be reference the insertion of Fig. \ref{fig:singleblock}.
\begin{figure}[ht]

\label{fig:singleblock}
\end{figure}
If you need cite a reference like this \cite{Erdos01}, and a sample bibliography item is attached at the end.
\subsection{Interface Definition}\label{sub:Interface}
In this section, the interfaces among the blocks of top level should be described in details. Tables can be used in latex as this. Table \ref{tab:signaldef}
\begin{table}[htp]
\caption{Signals Definition for Test Mode}\label{tab:signaldef}
\begin{center}
\begin{tabular}{|l|l|l|p{6cm}|}
\hline
\textbf{Signal Name} & \textbf{Direction} & \textbf{Width} & \textbf{Function}\\ \hline \hline
boot & Input & 1-bit & Trigger the boot test mode,
set to 0 in CPU regular process mode\\ \hline
test\_im\_wr & Input & 1-bit & Instruction memory write enable in test mode,set to 0 in
CPU regular process mode. In test mode, it will be set to 1 when if writing instructions to imem, otherwise it is set to 0.\\ \hline
test\_im\_re & Input & 1-bit & Instruction memory read enable in test mode,set to 0 in
CPU regular process mode. In test mode, it will be set to 1 when if reading instructions out, otherwise it is set to 0. \\ \hline
test\_im\_addr & Input & 32-bit& Instruction memory address\\ \hline
test\_im\_in & Input & 32-bit& Instruction memory data input for test mode. \\ \hline
test\_im\_out & Output& 32-bit& Instruction memory data output for test mode. \\ \hline
test\_dm\_wr & Input & 1-bit & Data memory write enable in test mode,set to 0 in
CPU regular process mode. In test mode, it will be set to 1 when if writing data to dmem, otherwise it is set to 0.\\ \hline
test\_dm\_re & Input & 1-bit & Data memory read enable in test mode,set to 0 in
CPU regular process mode. In test mode, it will be set to 1 when if reading data out, otherwise it is set to 0.\\ \hline
test\_dm\_addr & Input & 32-bit& Data memory address\\ \hline
test\_dm\_in & Input & 32-bit& Data memory input for test mode. \\ \hline
test\_dm\_out & Output& 32-bit& Data memory output for test mode. \\ \hline
valid & Output& 1-bit & If CPU stopped or any exception happens, valid signal is set to 0.\\
\hline

\section{Code}\label{sub:app.code}
Please add your code with Scala syntax highlight support like below.This is app \ref{sub:app.code}
\begin{scala}
class TopIO extends Bundle() {
val boot = Input(Bool())
// imem and dmem interface for Tests
val test_im_wr = Input(Bool())
val test_im_rd = Input(Bool())
val test_im_addr = Input(UInt(32.W))
val test_im_in = Input(UInt(32.W))
val test_im_out = Output(UInt(32.W))
val test_dm_wr = Input(Bool())
val test_dm_rd = Input(Bool())
val test_dm_addr = Input(UInt(32.W))
val test_dm_in = Input(UInt(32.W))
val test_dm_out = Output(UInt(32.W))
val valid = Output(Bool())
}
class Top extends Module() {
val io = IO(new TopIO())//in chisel3, io must be wrapped in IO(...)
//...
when (io.boot & io.test_im_wr){
imm(io.test_im_addr) := io.test_im_in
} .elsewhen (io.boot & io.test_dm_wr){
// please finish it
} //...
}
