ec79ic903a-LXilinx added power efficient Spartan-3A DSP devices to its XtremeDSP portfolio for signal processing applications. The devices offer DSP capabilities in a low-power FPGA for applications such as tactical radios for military communications, wireless access points and portable medical equipment. The Spartan-3A DSP low power (LP) devices are said to deliver a 50 percent static power savings, and a 70 percent savings while in suspend mode, compared to the standard devices, and they are available in industrial rated grades. The Spartan-3A DSP 3400A LP devices have provide 4.06 GMACs per mW at a speed of 250 MHz in the lowest cost speed grade. The DSP FPGA platform's ability to perform signal processing functions without the need to consume logic resources enables designers to meet their performance and cost goals while enabling better power efficiency. The XtremeDSP DSP48A slices that make up the dedicated DSP circuitry include dedicated 18 x 18 multipliers along with 18-bit pre-adder and 48-bit post-adder/accumulator to deliver desirable performance of DSP functions at a low cost. Power efficiency can also be derived from the advanced static power management suspend mode feature in the Spartan-3A DSP FPGA platform, which reduces FPGA power consumption while retaining the FPGA's configuration data and maintaining the application state.
