Description
ramfuncs
Time critical code is placed here. It is copied from FLASH to
RAM after the device is brought out of reset
csmpasswds
The CSM(128-bit) password is written to this location
csm_rsvd
The section of FLASH(120 words) prior to the password
locations are reserved locations and must not be written to
FFTtf
Section for the FFT Twiddle Factors
FFTipcb
Section for the complex FFT input buffer. The default size is
4096 words (1024 inputs * 2 complex * 2 32-bits wide). This
buffer must be aligned to 4*N word space. In this case, since the
buffer is allocated to the start of a RAM block, alignment is not
required.
ArcTest
The test vectors are allocated to this section
RawAdcBuffer
The raw ADC capture buffer is allocated to this section
