Integrated Device Technology Inc is pushing its IPBus peripheral bus as potential standard for system-on-a-chip-devices, and launched two new system controllers using the technology. The 64-bit RC64145 and 32-bit RC32134 controllers use the IPBus as the primary interconnect to connect memory and IDT modules. The goal of IDT’s work with the IPBus is to develop integrated low-cost core controllers using the firm’s MIPS processor core designs, with modules from the current system controllers and the IPBus as an internal backbone controlling I/O and memory operations. The Santa Clara, California microprocessor and memory maker discounts the rival PCI interconnect specification as too costly for system-on-a-chip applications
