Architecture-mapped concurrent-transform programmable 2D FIR filters for serial image processing

Architecture-mapped concurrent-transform programmable 2D FIR filters for serial image processing
Architecture-mapped concurrent-transform programmable 2D FIR filters for serial image processing
This paper presents a new approach to 2-D FIR filters using concurrent image transformation, negating pipeline delay penalties and reducing same-size convolution edge effects associated with sequential-transform filters realised in hardware while maintaining direct programmability. The new filters are suitable for FPGA and CPLD when a logic mapping technique is applied, which also maximises operational speed to provide video signal processing rates. An example 5-tap filter achieves 42 MHz clock frequency giving a 10.5 MHz pixel processing rate.

Abstract

This paper presents a new approach to 2-D FIR filters using concurrent image transformation, negating pipeline delay penalties and reducing same-size convolution edge effects associated with sequential-transform filters realised in hardware while maintaining direct programmability. The new filters are suitable for FPGA and CPLD when a logic mapping technique is applied, which also maximises operational speed to provide video signal processing rates. An example 5-tap filter achieves 42 MHz clock frequency giving a 10.5 MHz pixel processing rate.
