External Memory Instructions

The mapping of logical address L to physical address P for instructions (bank 0 only)

is dependent on the memory width w and whether the code is VISA or ISA:

For ISA code: P = (48/w) * L

For VISA code: P = (16/w) * L;

The impact of these items is that a user-written LDF imported from VisualDSP may

cause the CCES 1.0.1 linker to generate errors where none appeared before. As a

temporary work-around new external memory overlap errors may be inhibited by

specifying the linker option -nomema; this turns off external memory address

translation.

To eliminate such errors permanently will require editing of the LDF MEMORY

statement for external memory regions: the keyword SYNCHRONOUS or

ASYNCHRONOUS should be added and the logical address range amended, if

necessary, to be compatible with those specified in the linker xml file for the processor.

Examples usage

The supported method to find and open examples with CrossCore Embedded Studio is

via the Example Browser which is included in the release. Examples should also build

and run correctly if they are opened in-place with Eclipse's "Import Project" menu.

Importing examples with the "Copy To Workspace" tickbox selected may result in

examples which do not build and/or run as expected.

Version Compatibility

This is to provide users with information for use in updating an existing application that

was developed with the previous version of the product.

Macro Changes for ADSP-BF60x Headers

This release defines macros in the ADSP-BF60x processor headers that correspond to

the ADSP-BF60x Blackfin (r) Processor Hardware Reference, Preliminary Revision 0.4,

May 2012.

Your code may need changes if it relied on the defBF609.h / cdefBF609.h headers in

the CCES 1.0.0 release. The following are the incompatibilities to be aware of:

 DDR macros are now prefixed as DMC

CCES 1.0.0 names were ones such as REG_DDR0_CFG,

BITM_DDR_CFG_EXTBANK, ENUM_DDR_CFG_EXTBANK1. With DMC as the

prefix, these are now REG_DMC0_CFG, BITM_DMC_CFG_EXTBANK,

1 2 ... 11 12 13 14 15 16 17 18 19 20 21 ... 39 40
