Loader for ADSP-2126x/2136x/2137x SHARC Processors The ADSP-2126x/2136x/2137x processor uses eleven block tags, a lesser number of tags compared to other SHARC predecessors. There is only one initialization tag per width because there is no need to draw distinction between pm and dm sections during initialization. The same tag is used for 16-bit (short word), 32-bit (normal word), and 64-bit (long word) blocks that contain only zeros. The 0x1 tag is used for ZERO_INIT blocks of 16-bit, 32-bit, and 64-bit words. The 0x2 tag is used for ZERO_INIT blocks of 40-bit data and 48-bit instructions. For clarity, the letter L has been added to the names of the internal block tags. L indicates that the associated section header uses the logical word count and logical address. Previous SHARC boot kernels do not use logical values. For example, the count for a 16-bit block may be the number of 32-bit words rather than the actual number of 16-bit words. Only four tags are required to handle an external memory, two for each packing mode (see “Packing Options for External Memory” on page 5-6) because parallel port DMA is the only way to access the external memory. The external memory can be accessed only via the physical address of the memory. This means that each 32-bit word corresponds to either four (for 8-bit) or two (for 16-bit) external addresses. The EXT appended to the name of the block tag indicates that the address is a physical external address. The 0xB tag is for multiprocessor systems, exclusively supported on ADSP-21367/21368/21369 and ADSP-2137x processors. The tag indicates that the header is a processor ID header with the ID values and offset values stored in the header. Two data tags, USER_MESG and FINAL_INIT, differ from the standard format for other SHARC data tags. The USER_MESG header is described on page 5-17 and the FINAL_INIT header on page 5-29.
