General Description
Multi-channel FIR filter permits any number of inputs to be multiplexed into the same filter architecture. Much cheaper than using multiple FIR filter designs in parallel. Ideal for filtering dual-channel inputs such as complexed valued I/Q.
Key Design Features
– Systolic array for speed and scalability
– Up to 8 independent channels (more on request)
– Resources shared between all channels
– Configurable coefficients for each channel
– Configurable data width
– Configurable number of taps
– Symmetric arithmetic rounding
– Output saturation or wrap modes
– Much cheaper than using multiple FIR filters in parallel
– FPGA sample rates in excess of 550 MHz
– Matlab®, FDAtool and Simulink® compatible
Applications
– High-speed filtering applications
– Efficient multi-channel filter designs
– Dual-channel inputs e.g. complex I/Q
– Parallel DSP architectures
