  • LECTURE 5 Single-Cycle Datapath and Control
    Single-Cycle LECTURE 5 Datapath and Control PROCESSORS In lecture 1, we reminded ourselves that the datapath and control are the two components that come together to be collectively known as the processor. • Datapath consists of the functional units of the processor. • Elements that hold data. • Program counter, register file, instruction memory, etc. • Elements that operate on data. • ALU, adders, etc. • Buses for transferring data between elements. • Control commands the datapath regarding when and how to route and operate on data. MIPS To showcase the process of creating a datapath and designing a control, we will be using a subset of the MIPS instruction set. Our available instructions include: • add, sub, and, or, slt • lw, sw • beq, j DATAPATH To start, we will look at the datapath elements needed by every instruction. First, we have instruction memory. Instruction memory is a state element that provides read-access to the instructions of a program and, given an address as input, supplies the corresponding instruction at that address. ­ Code can also be written, e.g., self-modifying code DATAPATH Next, we have the program counter or PC. The PC is a state element that holds the address of the current instruction. Essentially, it is just a 32-bit register which holds the instruction address and is updated at the end of every clock cycle. ­ Normally PC increments sequentially except for branch instructions The arrows on either side indicate that the PC state element is both readable and writeable. DATAPATH Lastly, we have the adder. The adder is responsible for incrementing the PC to hold the address of the next instruction.

    Object-Oriented Development for Reconfigurable Architectures Von der Fakultät für Mathematik und Informatik der Technischen Universität Bergakademie Freiberg genehmigte DISSERTATION zur Erlangung des akademischen Grades Doktor Ingenieur Dr.-Ing., vorgelegt von Dipl.-Inf. (FH) Dominik Fröhlich geboren am 19. Februar 1974 Gutachter: Prof. Dr.-Ing. habil. Bernd Steinbach (Freiberg) Prof. Dr.-Ing. Thomas Beierlein (Mittweida) PD Dr.-Ing. habil. Michael Ryba (Osnabrück) Tag der Verleihung: 20. Juni 2007 To my parents. ABSTRACT Reconfigurable hardware architectures have been available now for several years. Yet the application devel- opment for such architectures is still a challenging and error-prone task, since the methods, languages, and tools being used for development are inappropriate to handle the complexity of the problem. This hampers the widespread utilization, despite of the numerous advantages offered by this type of architecture in terms of computational power, flexibility, and cost. This thesis introduces a novel approach that tackles the complexity challenge by raising the level of ab- straction to system-level and increasing the degree of automation. The approach is centered around the paradigms of object-orientation, platforms, and modeling. An application and all platforms being used for its design, implementation, and deployment are modeled with objects using UML and an action language. The application model is then transformed into an implementation, whereby the transformation is steered by the platform models. In this thesis solutions for the relevant problems behind this approach are discussed. It is shown how UML can be used for complete and precise modeling of applications and platforms. Application development is done at the system-level using a set of well-defined, orthogonal platform models.
