All the devices featured are pin compatible,<br />
allowing system scalability from one to<br />
six cores.<br />
<strong>Freescale</strong>’s multicore DSP devices offer<br />
unprecedented I/O and memory bandwidth with<br />
the ability to combine Serial RapidIO, Gigabit<br />
Ethernet and/or PCI Express, typically used for<br />
high bandwidth FPGA connectivity. One or two<br />
64-bit DDR2/3 interfaces will support the most<br />
data-intensive applications, such as medical<br />
image reconstruction.<br />
The MSC815x device family features the MAPLE<br />
hardware accelerator with dedicated DFT/FFT<br />
functions capable of running up to 350 Mega<br />
samples/sec. Offloading these functions from<br />
the cores leaves ample processing headroom<br />
for additional system requirements or enables<br />
the use of single- or dual-core devices (such as<br />
the MSC8151 and MSC8152 DSPs).<br />
The MSC825x family features one to six<br />
DSP SC3850 cores without the hardware<br />
accelerator for maximum flexibility in algorithm<br />
implementation and improved power efficiency.<br />
