To provide a good balance between the performance and flexibility of future digital control platforms, we propose an FPGA-based heterogeneous multiprocessor approach, in which the platform is composed of processing elements from a set of parameterizable heterogeneous Application-Specific Instruction-set Processors (ASIPs), connected with an hierarchical interconnect. With a case-study treating two...
The Generalized Hough Transform (GHT) is a widely known image processing method to find arbitrary shapes in images. In the first part of this work, we present an extension of the Hough voting scheme to perform the disparity calculation of stereo correspondence. The approach is optimized for a hardware implementation in terms of processing regularity, data storage requirements and pipelining. The second...
Embedded applications in the field of wireless sensor nodes are becoming more and more sensitive to energy consumption. Actually, this latter not only depends on the autonomy of the hardware part of network elements but also on the applications they support. Designers must so take into account the constraint of energy consumption when specifying and designing an application. Instead of considering...
Functional broadside tests are two-pattern scan-based tests that avoid overtesting by ensuring that a circuit traverses only reachable states during the functional clock cycles of a test. In addition, the power dissipation during the fast functional clock cycles of functional broadside tests does not exceed that possible during functional operation. On-chip test generation has the added advantage...
This paper introduces new capability on System on a Chip (SoC) ATE, called "Functional Test Abstraction (FTA)", which allows us to execute an automatically generated system level functional test program from the system level design verification environment. The device under verification and device under test can be a complex SoC which has multiple logic time domains and multiple interfaces...
This study explores how virtual flux estimation may be applied to the grid synchronization of an aerospace S/G system. This technique is used to make the converter more resilient to the grid distortion to be expected on an aircraft distribution bus. The performance of the proposed system is assessed in simulation and hardware. It is demonstrated how using the virtual flux technique the converter is...
Wide SIMD-based GPUs have evolved into a promising platform for running general purpose workloads. Current programmable GPUs allow even code with irregular control to execute well on their SIMD pipelines. To do this, each SIMD lane is considered to execute a logical thread where hardware ensures that control flow is accurate by automatically applying masked execution. The masked execution, however,...
