Within Philips Research Labs, we are investigating the 64-bit VLIW core for future TriMedia processors. We have performed an extensive Design Space Exploration (DSE) on this core using quantitative analysis, using a benchmark suite of applications which are representative for multi-media processing. We have explored, among others, the configurations of the(More)
In this paper an algorithm and architecture for computing the eigenvalue decomposition (EVD) of a symmetric matrix is presented. The EVD is computed using a Jacobi-type method, where the angle of the rotations is approximated by an angle k , corresponding to an orthonormal {rotation. These orthonormal {rotations are based on the idea of CORDIC and share the(More)
At Philips Research Labs, we are investigating the 64-bit VLIW core (also called CPU64) for future TriMedia processors. This processor is targeted towards embedded mul-timedia applications. In order to be able to perform a quantitative design space exploration, a set of benchmark applications has been developed which is representative of the application(More)
CORDIC based IIR digital lters are orthogonal lters whose internal computations consist of orthogonal transformations. These lters possess desirable properties for VLSI implementations such as regularity, local connection, low sensitivity to nite word-length implementation, and elimination of limit cycles. Recently, ne-grain pipelined CORDIC based IIR(More)
