Standardized FPGA Logic Drive Architecture for Lower NRE Cost

The system segments the logic drive function across multiple FPGA IC chips working in parallel, with each chip handling a portion of the workload. This allows the use of smaller, more cost-effective FPGA chips at advanced technology nodes while maintaining overall system capability through parallel processing architecture.

The patent creates a universal logic drive platform using standardized FPGA chips that can be programmed for different applications. The same hardware platform serves multiple functions through field-programmable logic, eliminating the need for custom ASIC designs for each application and reducing fabrication costs at advanced nodes.

The logic drive functionality is segmented across multiple smaller FPGA chips rather than requiring one large FPGA chip. Each individual chip has a reduced footprint, and the collective array of chips provides the necessary adaptability and processing capacity through parallel operation.

The patent transitions from a single-chip architecture to a multi-chip array architecture, effectively moving the problem from two-dimensional chip area constraints to a three-dimensional system-level arrangement where multiple smaller chips are organized in a package or substrate.

The system divides the computational workload across multiple FPGA chips, allowing each chip to operate at lower power levels. The segmented architecture enables more efficient power management where only active logic regions in each chip consume significant power, rather than a single large FPGA chip where more logic is simultaneously active.

The patent implements dynamic power management where FPGA logic regions are activated or deactivated based on workload demands. This periodic or on-demand activation reduces average power consumption while maintaining adaptability, as chips or logic regions can be powered down when not needed and activated when required.

The patent creates a dynamic system where the logic drive can be reprogrammed in the field to adapt to different workloads and applications. This dynamic reconfigurability provides ASIC-like performance for specific applications while avoiding the high NRE costs of custom ASIC design, as the same hardware platform can be software-defined for different functions.

The system changes the operational parameters of the FPGA chips through field programming and configuration, optimizing performance for specific applications without requiring physical hardware changes or expensive custom fabrication. Parameter changes in the logic configuration achieve ASIC-like specialization while maintaining the flexibility and lower NRE cost of programmable devices.
