cksla very nice read
"By eliminating the controller, designers save money and power"
Blue Wave Systems utilizes the TI DSP-BIOS2, as it's core structure(Comstruct)
The DSP-BIOS2 has some real fancy memory management, and I still have my thoughts on it, mainly because of the way it formats memory. Combined embedded or stand alone, to have this ability they would have to have removed the controller schemes between the memories, IMO.
I must say, it does have a form of file management(though not explained in detail) capability, and very scalable as far as memory management.
With TI having this DSP-BIOS kernel, what was the reason for the e.Digital partnership ? The functions seem to me, to be very similar IMO. DSP-BIOS is not explained in detail (only to the fact of what it does), and to my knowledge, there are no patents to follow, to see exactly what it is all about. Three main categories of the DSP_BIOS Kernel are Memory Management, Event handling, and Stream I/O.
e.Digital is on the right track, with an Embedded RTOS, for device management bios low level and event handling high level APIs{Application Program Instructions ); file management; cross platform memory management of flash memory, HDD, optical drives; adaptable to use many conventions of existing file structures of operating systems; fault tolerant system utilizing a minimum of cache equal to one read/write block; contiguous or noncontiguous storage; Physical link memory management with or without file structure-rootdir/subdir, fully structured within the flash (compared to typical virtual map management be it bitmapping or link list allocation types structured through RAM/flash combinations); two schemes of streaming data I/O to and from flash; eliminates flash memory controller; flash memory life cycle management; security management
