Denali Software announced its first embedded software product offering known as the Spectra flash file system. Spectra provides embedded system developers with a flash file system that delivers performance from any commercially available NAND or NOR flash device. Spectra enables system developers to deploy flash memory systems for a variety of applications, ranging from handsets to network routers running multi-threaded applications. Spectra can be used alone or with Denali’s Databahn memory controller product for NAND and NOR flash memory. All Databahn products are supported by a IP configuration infrastructure that includes integration with a database of memory device models for functional verification, performance analysis and optimal use of device specific features, functions and timing.
