Xilinx, Inc. (Nasdaq: XLNX) Automotive (XA) Spartan(TM)-3A and Spartan-3A DSP FPGAs are domain-optimized solutions for high I/O-logic ratio and high-bandwidth digital signal processing (DSP) with low power consumption and advanced design security to the development of infotainment, hybrid cluster, and driver assistance systems. Engineers can immediately begin designing with commercial XC versions of the Spartan-3A and Spartan-3A DSP devices and current Xilinx development tool suite. XA Spartan-3A FPGAs will ship in the second quarter of 2008 starting at under $8.50 USD for devices with 200K system gates, followed by XA Spartan-3A DSP devices in the third quarter starting at under $32.00 USD with 1.8 million system gates. Prices are for 50K unit volumes in the smallest package and automotive I-Grade temperatures.
XA Spartan-3A FPGAs feature the highest number of I/O per logic cell with broad connectivity support. XA Spartan-3A DSP devices add more logic, memory, and XtremeDSP(TM) slices, packing more raw DSP throughput than any other low-cost PLD device, with parallel processing power on a scale never before seen in automotive electronics. The two new device families are ideal for TFT displays, image and video processing, and in-vehicle networking in automotive applications.
XA Spartan-3A devices are I/O-optimized for the lowest cost per I/O in the PLD industry with up to 1.4 million system gates and 502 I/Os. They are the only FPGAs compliant with 26 popular single-ended and differential signaling standards, and also support market-specific networking standards, such as CAN, MOST(R) and FlexRay. These devices use source-synchronous interfacing technology cost-optimized to ensure optimal design margins. They also introduce an array of innovations that include dual-power management (suspend and hibernate modes); device configuration capabilities; reduction in the number of power rails (power lines going into the device) from three to two; and permanent DeviceDNA serial numbering to safeguard hardware and software intellectual property (IP).
XA Spartan-3A DSP devices deliver over 30 GMACS and 2200 Gbps memory bandwidth, closing the bandwidth gap automotive designers face with current serial DSP designs. The cost-optimized XtremeDSP DSP48A slice enables designers to implement many independent arithmetic functions. Multiple slices can be connected together without the use of general logic fabric, reducing power consumption while delivering very high performance and efficient silicon utilization. These slices combined with hard-coded DSP pre-adder and multiply accumulate (MAC) blocks provide more than enough processing capacity to execute complex image algorithms much faster than any serial DSP on the automotive market today. In addition, the XA Spartan-3A DSP family provides up to 53,712 logic cells, 2268 Kbits of performance-enhanced Block RAM, and 373 Kbits of distributed RAM that collectively can be configured to optimize for a broad range of signal processing requirements.
