GCache is an FPGA-based key-value database to efficiently store and retrieve cached data. Network stacks are implemented on FPGA to receive data from fast speed networks completely bypassing any type of operating systems and software layers. Key-value store algorithms are implemented completely on FPGA to handle Memcached compatible operations. Direct connection with DRAM from FPGA is used to stream data to memory for storage and retrieve the data on demand.
Regular expressions are specially encoded text strings used as patterns for matching sets of strings. GRegeX is an implementation of standard regular expression algorithm on FPGA chip achieving 12.8 GB/s throughput with a single IP core. Wide range of supported regular expression functions allows developers configure desired rules which can be handled in a chip without reducing the throughput. The target applications include: Smart firewalls, Security and Log Text analysis.
