Abstract:
In this thesis we propose to realize the performance benefits of applicationspecific hardware optimizations in a general-purpose, multi-user system environment using a dynamically extensible microprocessor architecture. We have called our dynamically extensible microprocessor design the Extensible Microprocessor without Interlocked Pipeline Stages, or eMIPS. The eMIPS architecture uses the interaction of fixed and configurable logic available in modern Field Programmable Gate Array (FPGA). This interaction is used to address the limitations of

Abstract:
Recently, the power and energy consumed by a chip has become a primary design constraint for embedded systems and is largely aaffected by software. Because aims vary with the application domain, the best program is sometimes the most power or energy efficient one rather than the fastest. However, there is a gap between software and hardware that makes it hard to predict which code consumes the least power without measurement. Therefore, it is vital to discover which factors can affect a program's power and energy consumption. In this thesis we present an instruction level model to estimate the

Abstract:
Transient-execution attacks have been deemed a large threat for microarchitectures through research in recent years. In this work, I reproduce and develop transient-execution attacks against RISC-V and CHERI-RISC-V microarchitectures. CHERI is an instruction set architecture (ISA) security extension that provides fine-grained memory protection and compartmentalisation. I conduct transient-execution experiments for this work on Toooba – a superscalar out-of-order processor implementing CHERI-RISC-V. I present a new subclass of transient-execution attacks dubbed Meltdown-CF(Capability Forgery).

In order to avoid possible mistakes arising during the programming task, we rearrange the memory management of the designed CPU by changing the address of the special function register to FFH.
