Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 83 === A application-specific VLSI chip that can compute the discrete
cosine, sine, Fourier and Hartley transforms in a real-time
manner is presented. A generic processor based on the Impulse
Response) recursive approach for those discrete is described.
This processor is well suited for VLSI because it is modular,
regular, local connected and without any limitation on
transform size N. Compared with the functionality discrete
transform chips available, this chip can support four different
transforms. To achieve various transform computation, a memory-
oriented architecture is used. To increase operation a
pipelined designed is adopted. A 16-bit data length can achieve
the operation precision. In this processor, a simple error
circuit is also included to detect the memory error. This of
the processor using 0.8 um SPDM CMOS technology can achieve 480
Mb/s data processing rate.
