Your task in this lab is to build a simulator that is able to execute programs that use the MIPS subset we have discussed in class. You will be working with the MIPS single cycle datapath and control as described in Chapter 4 and shown in Figure 4.24 of Patterson and Hennessy. The designer plans to modify the datapath and control signal based on the processor showed in next page. It’s a textbook processor with some missing blocks and wiring to fill in. The components he can use are any of the blocks already present in the design and the generalized 21. List the five stages of a pipelined datapath and define them. 22. Define the Least Recently Used (LRU) replacement scheme for caches and explain why it is most commonly used. 23. Explain why hazards exist when pipelining is used and how they can be avoided. 24. The MIPS Datapath 1. ... • for addi, read one register • for jal, no reads necessary 16. Computer Science 61C Spring 2017 Friedland and Weaver Stages of Execution ... Implementation of a MIPS processor in VHDL This laboratory work describes the design of a simplified MIPS processor and some guidelines for its implementation in VHDL. The outcome will be an implementation of the simplified MIPS processor, which will be tested through simulation. 1. MIPS instruction set architecture

It’s a textbook processor with some missing blocks and wiring to fill in. The components he can use are any of the blocks already present in the design and the generalized MIPS Instruction Reference. This is a description of the MIPS instruction set, their meanings, syntax, semantics, and bit encodings. The syntax given for each instruction refers to the assembly language syntax supported by the MIPS assembler.

NOTE: To control the datapath we will start off by manually emulating the control unit, that is, manually control the output from the control unit. Consider 8-bit subset using 8-bit datapath ... But, there is an addi instruction, and there’s a convenient register that’s always pinned to 0

RISC architecture has been adopted in designing the multi-cycle processor datapath and the ISA is 16-bits long. It is the first ever MCML processor that requires constant power dissi-pation unlike CMOS processors. Also, once optimized, power dissipation does not ... A datapath contains all the functional units and connections necessary to implement an instruction set architecture. —For our single-cycle implementation, we use two separate memories, an ALU, some extra adders, and lots of multiplexers. —MIPS is a 32-bit machine, so most of the buses are 32-bits wide.

Recommended for you Problems in this exercise assume that individual stages of the datapath have the following latencies: IF ID EX MEM WB 200ps 100ps 120ps 210ps 150ps 1.What is the clock cycle time in a pipelined and non-pipelined processor? 2.What is the total latency of an LW instruction in a pipelined and non-pipelined pro-cessor? For the datapath from Figure 4.24, draw the logic diagram for the part of the control unit that implements just the first signal. Assume that we only need to support LW, SW, BEQ, ADD, and J (jump) instructions. Repeat the previous question, but now implement both of the signals.

Unit 2: Single-Cycle Datapath and Control Part 1 of 2: Digitial Logic Review CIS371 (Roth/Martin): Datapath and Control 2 This Unit: Single-Cycle Datapaths •Digital logic basics •Focus on useful components •Mapping an ISA to a datapath •MIPS example •Single-cycle control •Implementing exceptions using control MemCPUI/O System ... Datapath with Support for Exceptions • Co-processor register (CR) file needn’t be implemented as RF • Independent registers connected directly to pertinent muxes — The outputs are values for the blue control signals in the datapath. Most of the signals can be generated from the instruction opcode alone, and not the entire 32-bit word. To illustrate the relevant control signals, we will show the route that is taken through the datapath by R- type, lw, sw and beq instructions. A single-cycle MIPS processor An instruction set architecture is an interface that defines the hardware operations which are available to software. Any instruction set can be implemented in many different ways. Over the next few weeks we’ll see several possibilities. —In a basic single-cycle implementation all operations take the same Jan 21, 2004 · okay, now that we [hopefully] understand how our single cycle cpu works, we will try the following exercises: if we are executing an addi instruction, what are the values of the control signals? what is the "sign extender", and why do we need it on our datapath? why can't we just use all zeroes for the top 16 bits of the extended immediate? This datapath can execute the following instructions: add, sub, and, or, nor, slt, addi, lw, sw, and beq . Complete the circuit for the datapath by adding appropriate multiplexors and logic gates and wiring them to the components that are already in place.
