Implementation of General Assembler
Husár, Adam ; Masařík, Karel (referee) ; Hruška, Tomáš (advisor)
This thesis describes the design of the universal assembler that represents a part of the Lissom project. You will be provided with the description of the assembler architectures and their usual tasks. Special attention is paid to GNU assembler. Designed assembler consists of the fixed and the generated part. The generated part is created automatically from the description of instruction set, that is defined using architecture and instructions set description language ISAC. Using this approach, it is possible to change assembler target architecture automatically. The second part of thesis describes the Parserlib2 library implementation that is a part of the Lissom project and provides the information about the target instruction set for an assembler generator.

Fast and Partially Translated Simulator for Application-Specific Processors
Richtarik, Pavel ; Krčma, Martin (referee) ; Zachariášová, Marcela (advisor)
The major objective of this work is to analyse possibilities of using simulation within the development of application-specific instruction-set processors, to explore and compare some common simulation techniques and to use the collected information to design a new simulation tool suitable for utilization in the processors development and optimization. This thesis presents the main requirements on the new simulator and describes the design and implementation of its key parts with emphasis on the high performance.

Transformation of a Processor Description in CodAL to SystemC Structures
Ondruš, Tomáš ; Hynek, Jiří (referee) ; Přikryl, Zdeněk (advisor)
The goal of this thesis is to create a generator of simulators and hardware representation of application specific processors in a SystemC language. An aim of the first part is to create a wrapper layer compatible with SystemC TLM 2.0 that wraps an existing simulator to avail modeling of transaction oriented systems. The second part is a generator of a hardware representation for the processor that is suitable not only for logical synthesis, but also for the simulation on a cycle accurate level. A final result is a state of the art solution comparable to existing generators.

Changes in pigmentation of animals during domestication
Ariskina, Sofya ; Hofmanová, Barbora (advisor) ; Kracíková, Olga (referee)
In this work there are described, based on different experiments, and on the basis of them written articles about changes of different types of animals in the course of domestikation. It is supposed that this process began 15 thousand years ago. Here a described main scenarios which show the reasons and ways of the beginning of domestication, and some main places where this process began.
But it is much more important that in the course of the domestication there was a big number of morphological, anatomic and physiological changes in which consequence wild animals gradually turned into domestic ones. These changes, whether it be considerable change of the corporal sizes, reduction of a brain, changes in nervous system, emergence of trailing ears or big quantity of various coat colors, testifies that animals lost the need to survive independently and began to depend partially or completely on people.
But a main goal of this work is to describe and explain the development of new, not existing in wild animals coat colors which are connected to the domestication process and, later, to the selection process, made by people. The general sign of all domesticated animals chosen and selected incidentally or intentionally on any signs is emergence of spottiness and heterogeneity of coat coloring, gradually turning into other colourings that are absolutely not typical for wild animals because in the wild nature would draw attention of predators or mark.
Also here is described the genetic component of process of emergence of new coat colors caused by a different ratio of an eumelanin and a feomelanin, and also various gene mutations (for ex. MC1R, ASIP ets.).

NIOS II Processor Model
Masařík, Marek ; Dolíhal, Luděk (referee) ; Zachariášová, Marcela (advisor)
This bachelor thesis deals with the implementations of Nios II processor model in the description language processor called description CodAL. The implementation of processor is on two levels of abstraction. First level of abstraction is the instruction accurate model and second is the cycle accurate model. An important part of processor design is testing and verification which were realized on the prepared benchmark set. The resulting processor can be potentially used in real applications.

Acceleration of Applications Using Specialized Instructions
Mikó, Albert ; Krčma, Martin (referee) ; Hruška, Tomáš (advisor)
The design of specialized instructions for application specific processors is a challenging task. This thesis describes the issues of effective specification and use of specialized instructions for optimization of applications. It focuses on improvements of the outputs and usability of the semiatomatic method of selection of specialized instructions to allow the optimization of complicated applications. This method combines manual selection of instructions by marking a section of source code in the application and automatic generation of the instruction description in the modelling language.

RISC-V Processor Model
Barták, Jiří ; Dolíhal, Luděk (referee) ; Zachariášová, Marcela (advisor)
The number of application specific instruction set processors is rapidly increasing, because of increased demand for low power and small area designs. A lot of new instruction sets are born, but they are usually confidential. University of California in Berkeley took an opposite approach. The RISC-V instruction set is completely free. This master's thesis focuses on analysis of RISC-V instruction set and two programming languages used to model instruction sets and microarchitectures, CodAL and Chisel. Implementation of RISC-V base instruction set along with multiplication, division and 64-bit address space extensions and implementation of cycle accurate model of Rocket Core-like microarchitecture in CodAL are main goals of this master's thesis. The instruction set model is used to generate the C compiler and the cycle accurate model is used to generate RTL representation, all thanks to Codasip Studio. Generated compiler is compared against the one implemented manually and results are used for instruction set optimizations. RTL is synthesized to Artix 7 FPGA and compared to the Rocket Core synthesis.
