FireCore is an IP core that integrates PHY and link layer controller (LLC) cores into a single IP product.
FireCore integrates the PHY and link layer requirements necessary for common 1394 devices into a single IP core. Based on the FireGate PHY IP core and FireLink LLC IP core, FireCore is designed to support data rates from S100 to S3200 and various host interfaces such as generic, OHCI, and OHCI (with AS5643 option). DapTechnology's new FireCore package offers unprecedented technical capabilities, features, flexibility, and options for customization and future expansion. Together with FireStack (DapTechnology's 1394 software stack), FireCore is designed to fully leverage the capabilities of the AS5643 extension. It aims to completely abstract the 1394 protocol layer and the AS5643 protocol layer, allowing implementers to focus entirely on system-level functionalities such as fault tolerance, fault isolation, and redundancy.

basic information
FireCore has three different variations. FireCore Basic a) Processor-driven data exchange (RX/TX to DPRAM) is ideal for non-OHCI and non-GP2Lynx-like designs, optimized for Mil1394 enhancement, minimal footprint, and resource utilization. b) 1394b PHY layer (FireGate) FireCore Extended: a) DMA-driven data transfer, optimized for OHCI and Extended OHCI features, Mil1394 extension, and high bandwidth throughput. b) 1394b PHY layer (FireGate) FireCore GPLink: Used as an alternative to TI GP2Lynx in common AS5643 device systems, paired with the 1394b PHY layer (FireGate). FireCore uses the same PHY IP, FireGate, across all variants of the three link layers. ■ Japanese technical documentation for AS5643 is available.
