Course details

Processor Architecture

ACH Acad. year 2016/2017 Winter semester 5 credits

Current academic year

The course covers architecture of universal as well as special-purpose processors. Instruction-level parallelism (ILP) is studied on scalar, superscalar and VLIW processors. Then the processors with thread-level parallelism (TLP) are discussed. Data parallelism is illustrated on SIMD streaming instructions and on graphical processors (SIMT). Parallelization of numerical calculations for GPU is also covered (CUDA). Techniques of  low-power processors are also explained.

Subject specific learning outcomes and competences

Overview of processor microarchitecture and its future trends, ability to compare processors and using suitable tools, simulate the influence of changes in their architecture. Get acquainted with processor performance measurement. The knowledge of architecture and hardware support of parallel computation on graphic processors can be directly applied for acceleration of intensive calculations. 

Learning objectives

To familiarize students with architecture of the newest processors exploiting the instruction-level, thread-level and data-level parallelism. To clarify the role of a compiler and its cooperation with CPU. To be able to orientate oneself on the processor market, to evaluate and compare various CPUs. Next to familiarize with architecture of graphical processors and its use for acceleration of numerical calculations (GPGPU), and with low-power techniques in processors for mobile applications.  

Prerequisite kwnowledge and skills

Von Neumann computer architecture, memory hierarchy, programming in assembly language, compiler's tasks and functions
