ASIC used to be the in-thing in programmable logic device configuration. It is now getting a fierce competition with the role played by Xilinx XC3S1200E’s Spartan-3 architecture. The architecture offers better alternatives to ASIC, including the zero-use of hardware replacements for design upgrades.
The Xilinx XC3S1200E Spartan-3E family also cuts down on FPGA design complexities and high costs. The longer configuration time is also tackled effectively.
Xilinx XC3S1200E’ Functional Elements
Here are some of the fundamental programmable function elements of the Xilinx XC3S1200E FPA family.
1. Digital Clock Manager
In addition to enabling the effective management of the clocks, the Digital Clock Manager (DCM) also phase-shifting clock signals, and self-calibration to the devices.
The additional functions of Xilinx XC3S1200E’s DCM are:
- Providing fully digital solutions for distributing clock signals.
- Enabling the division and multiplication of clock signals.
2. Configurable Logic Blocks (CLBs)
Configurable Logic Blocks (CLBs) are one of the fundamental components for building FPGAs. The Xilinx XC3S1200E is not an exception.
Xilinx XC3S1200E’s CLBs store data and perform a wide range of logical functions. The CLB also have the Look-Up Tables (LUTs), which aid in the storage of elements used as latches and flip-flops. The LUTs also help in the implemental of logic plus storage elements.
3. Multiplier Blocks
The Multiplier Blocks of the Xilinx XC3S1200E make inputs and calculate the same using the 18-bit binary numbers that serve as inputs.
4. Block RAM
Xilinx XC3S1200E’s Block RAM provides the data storage option in the form of 18-Kbit dual-port blocks.
5. Input and Output Blocks (IOBs)
These are the dedicated blocks that aid in the flow or transmission of data between the internal logic and I/O pins of the Xilinx XC3S1200E FPGAs.
The flow of data is bidirectional and works with 3-state operation. The IOBs also support multiple standards and registers, including Double Data-Rate (DDR), and four (4) high-performance standards.
Conclusion
The Xilinx XC3S1200E FPGAs combine advanced process technology to aid in cost reduction and improved system performance of the FPGAs.
