EMIF Control Registers
The C6416 has two external memory interfaces (EMIFs). One of these is 64 bits wide,
the other 16 bits.
The C60 contains several registers that control the external memory interfaces (EMIFs).
A full description of these registers can be found in the
SMT6400 help file .
The standard bootstrap will initialise these registers to use the following resources:
Memory space
(EMIF_A)
Resource Address range
Internal program memory (1M) 0x00000000 - 0x000FFFFF
CE0 SDRAM (64Mbytes) 0x80000000 - 0x83FFFFFF
CE1 SDRAM (64Mbytes) DSP_A
only 0x90000000 - 0x93FFFFFF
CE2 Virtex-II 0xB0000000 - 0xBFFFFFFF
Memory space
(EMIF_B)
Resource Address range
CE0 HPI of adjacent DSP 0x60000000 - 0x600000FF
CE1 2MB section of flash (DSP_A
only) 0x64000000 – 0x640FFFFF
CE2 FPGA PROG controls (DSP_A
only). Write to this address to
assert PROG and clear the
FPGA configuration. 0x68000000
CE3 FPGA CCLK control (DSP_A
only) 0x6C000000
The boot code sets-up the EMIF as follows:
GCTLB = 0x0001277C;
CECTL0A = 0x000000D0;
CECTL1A = 0x000000D0;
CECTL2A = 0xFFFFFF23
CECTL3A = 0x00000030;
SDCTRLA = 0x53227000;
CECTL0B = 0x10d20415;
