Code compression has been shown to be an effective technique to reduce code size in memory constrained embedded systems. It has also been used as a way to increase cache hit ratio, thus reducing power consumption and improving performance. This paper proposes an approach to mix static/dynamic instruction profiling in dictionary construction, so as to best(More)
This paper proposes a complete hardware solution for embedded systems that fully protects off-chip memory. Our security core is based on one-time pad (OTP) en-cryption and a CRC integrity check module. These modules safeguard external memories for embedded processors against a series of well-known attacks, including replay attacks, spoofing attacks and(More)
This paper describes a complete off-chip memory security solution for embedded systems. Our security core is based on a one-time pad (OTP) encryption circuit and a CRC-based integrity checking module.

Code compression, initially conceived as an effective technique to reduce code size in embedded systems, today also brings advantages in terms of performance and energy consumption, due to an increase in the cache hit ratio. This paper proposes the design of a code decompressor engine for our dictionary-based method, embedding it into the Leon (SPARC V8)(More)
Code Compression has been used to alleviate the memory requirements as well as to improve performance and/or minimize energy consumption. On the other hand, implementing security primitives on Embedded Systems is always costly in terms of area and performance. In this paper we present a code compression method, the IBC-EI (instruction based compression with(More)
BACKGROUND With the expected growth and aging of the population of primary central nervous system tumours (PCNST) survivors, attention to the radiation-induced late brain injury is fundamental. Late focal hemosiderin deposition (FHD) lesions, namely microbleeds and cavernomas, are among the presumable late cerebrovascular complications associated with(More)
BACKGROUND Brain radiotherapy plays a central role in the treatment of certain types of childhood primary central nervous system tumors. However, damage to surrounding normal brain tissue causes different acute and chronic medical and neurological complications. Despite the expected increase in number of childhood primary central nervous system tumor(More)

Code Compression has been shown to be efficient in minimizing the memory requirements for embedded systems as well as in power consumption reduction and performance improvement. In this paper we devise a code compression method, the IBC-EI (Instruction Based Compression with Encryption and Integrity checking), tailored to provide integrity checking and(More)
