the aim of this cross-sectional study was to explore the association of crystalline silica aerosols exposure with malondialdehyde in blood serum and urinary neopterin and explore their potential as biomarkers of their external exposure. nonsmoking and healthy male glass sandblasters and control population were randomly selected for this study. all groups were monitored for their personal exposu...

This paper describes the real-time software implementation of NTSC Analog TV on the Sandblaster SDR platform. The platform supports realtime execution of a number of communication protocols and multimedia applications, including: 802.11b, WCDMA, GSM, GPS, MPEG4, H.264 and others. Our implementation of analog TV runs in real-time on Sandblaster evaluation board and produces highquality visual ou...

This paper describes a Sandbridge Sandblaster system implementation including both hardware and software elements for a WiMax 802.16e system. The system is implemented on the fully functional multithreaded Sandblaster multiprocessor SB3010 SoC chip. The entire communication protocol, physical layer and MAC, has been implemented in software using pure ANSI C programming language and it executes ...

Software-defined radio (SDR) is an emerging technology that facilitates having multiple wireless communication protocols on one device. Previous work has shown that current W-CDMA, GPS, GSM, and WiMAX applications can run on this class of device while consuming significant processing power. Next generation wireless networks require speeds in excess of 50Mbps. Some of the fastest AES software im...

In order to limit the damage of malware on Mac OS X and iOS, Apple uses sandboxing, a kernel-level security layer that provides tight constraints for system calls. Particularly used for Apple iOS, sandboxing prevents apps from executing potentially dangerous actions, by defining rules in a sandbox profile. Investigating Apple’s built-in sandbox profiles is difficult as they are compiled and sto...

—We describe the generation of the simulation environment for the Sandbridge Sandblaster multithreaded processor. The processor model is described using the Sandblaster architecture Description Language (SaDL), which is implemented as python objects. Specific processor implementations of the simulation environment are generated by programmatically calling the python objects. Using just-in-time ...

In this paper, we describe the design, implementation and multithreading of a MPEG 4 decoder (simple profile) for high resolution (VGA 640x480) on Sandblaster DSP. The implementation is done entirely in C. Software solution provides high reusability, low cost and short development time when compared to dedicated hardware solutions. We describe the multithreading of time critical tasks that are ...
