A real-time transform-based DSP

A real-time transform-based DSP

At 80 MHz, the BDSP91V24 COTS real-time transform-based DSP can perform a 1k complex fast Fourier transform in 45 µs. It can also process 8- to 24-bit data in real time using a multiport dataflow structure. An on-chip block-floating-point capability can perform automatic scaling or accept user-scaling factors for input data scaling. Fabricated using a 0.35-µm, three-metal, CMOS logic process, the 3.3-V DSP comes in a 352-pin super ball-grid array.
