Analysis of Cache Attacks and Countermeasures on the ρ-­VEX Processor

Modern implementations of encryption algorithms on CPU’s that use frequent memory lookups of precomputed functions, are vulnerable to Cache based Side­Channel Attacks. The ρ­-VEX processor, a runtime reconfigurable VLIW processor developed at the Computer and Quantum Engineering department at the TU Delft was identified to possibly allow for...

Dynamic cache configuration for the ρ-VEX platform

The ρ-VEX is a processor designed at the Computer Engineering lab at TU Delft to be reconfigurable at runtime, resulting in a processor that can combine or separate instruction lanes according to the program requirements. The current cache for the ρ-VEX processor is direct mapped and always identical to the instruction group configuration. This...

Dynamic Hardware Binary Translator for ρ-VEX

The last years, there has been a increasing trend in embedded system and FPGA im-plementations for greater flexibility and also, a rising adaptation of heterogeneous plat-forms. These platforms often include FPGAs and embedded cores side by side.ρ-VEXcore, developed and maintained by the Computer Engineering group of TU Delft, is aVLIW processor...

Accelerating Software Pipelines Using Streaming Caches

The trend of increasing performance by parallelism is followed by the adoption of heterogeneous systems. In order to allow more fine-tuned balancing between used thread- and instruction level parallelism, the heterogeneous ρ-VEX platform was developed. Pipelining has been a part of microprocessor development for decades to increase throughput of...

Streaming FPGA Based Multiprocessor Architecture for Low latency Medical Image Processing

In this work a fast and efficient implementation of a Field Programmable Gate Array (FPGA) based, fixed hardware, streaming multiprocessor architecture for low latency medical image processing is introduced. The design of this computation fabric is based on the ρ-VEX Very Long Instruction Word (VLIW) softcore processor and is in influenced by...

Acceleration of Fingerprint Minutiae Extraction Using a VLIW Processor

Deze scriptie beschrijft het ontwerp van een embedded systeem dat de kenmerkende eigenschappen uit de afbeelding van een vingerafdruk haalt. Het betreft een hardware/software codesign, waarbij een VLIW-processor als accelerator is gebruikt.

Interrupt support on the ?-VEX processor

In this thesis, we present a design of interrupt system upon an extensible and reconfigurable VLIW softcore processor: r-VEX. This interrupt system is designed and implemented in four mechanisms to match different application requirements in terms of the hardware consumption and performance issues (interrupt latency). On the other hand, due to...

Fingerprint Verification on the VEX Processor

The speed gap between a processor realized in Semi-custom ASIC technology and a processor realized in FPGA technology is narrowing. In processor design, the approach is to define the microarchitecture of the processor and to design and implement it for executing an application domain. In this thesis, we have investigated the approach to design a...
