HiNT Corp. has announced the availability of what it claims to be world's first 133MHz, 5V-tolerant PCIX-PCIX dual mode universal bridge for high-speed storage and networking platforms. HB8 also provides users with the means to PCIX-enable their PCI products.

Available in a 380-ball, 27-by-27mm PBGA package, the bridge features improved I/O buffer timing and driving designs that allow the support of more than one PCIX loading at 133MHz. It also features 5V-tolerant buffers that allow new products to be compatible with legacy PCI systems.

The HB8 can operate in PCIX to PCIX bridging, PCIX to PCI conversion, or high fan out PCI to PCI bridging. It uses the company's Non-Transparent Bridging architecture to allow efficient PCIX-PCIX and PCIX-PCI bridging of I/O processors, DSPs, and other intelligent PCI/PCIX masters, the company said. For PCIX to PCI conversion, it uses the company's Flow-Thru architecture to provide PCI masters with optimal burst performance to the PCIX bus.

It also features the company's Dynamic-Buffer-Management function, which is a link list-based buffer control to dynamically allocate buffer size associated with each PCIX master for efficient and high-speed transfer of PCIX data. In addition, the HB8 allows fixed 1K buffer size allocation for each entry when necessary.

Other features of the device include a Smart-Prefetch function and CPCI universal bridging. The Smart-Prefetch allows the HB8 to provide data prefetch, store, and forward service to secondary bus PCI bus based intelligent masters.

CPCI universal bridging is done via the device's universal mode that permits jumper-less configuration between application to CPCI interface at Peripheral Slot and System Slot. The HB8 can be configured as a transparent bridge in a system slot supporting a host, or as a non-transparent bridge in a peripheral slot as an intelligent subsystem.
