Programmable control interface (SPI/I2C).
●
GPIO.
●
PLL clock oscillator.
6.3
Data and program memory
Each of the memories are described below.
6.3.1
1024 x 24-Bit X-RAM (XRAM)
This is a 1024 x 24-Bit single port SRAM used for storing coefficients. The 16-Bit XRAM
address, XABx(15:0) is generated by the address generation unit of the DSP core. The 24-
Bit XRAM Data, XDBx(23:0), may be written to and read from the data ALU of the DSP core.
The XDBx Bus is also connected to the internal bus switch so that it can be routed to and
from all peripheral blocks.
6.3.2
1024 x 24 Bit Y-RAM (YRAM)
This is a 1024 x 24-Bit single port SRAM used for storing coefficients. The 16-Bit address,
YABx(15:0) is generated by the address generation unit of the DSP core. The 24-Bit Data,
YDBx(23:0), is written to and read from the Data ALU of the DSP core. The YDBx Bus is
also connected to the internal bus switch so that it can be routed to and from other blocks.
6.3.3
3072 X 24-Bit Program RAM
This is a 3072 x 24-Bit single port SRAM used for storing and executing program code. The
16-Bit PRAM Address, PABx(15:0) is generated by the program address generator of the
DSP core for instruction fetching, and by the AGU in the case of the move program memory
(MOVEM) instruction. The 24-Bit PRAM Data (program code), PDBx(23:0), can only be
written to using the MOVEM instruction.
During instruction fetching the PDBx bus is routed to the program decode controller of the
DSP core for instruction decoding.
Spare space in the program area may be used as data memory to implement delay lines for
example.
6.3.4
512 x 24-Bit Bootstrap ROM (Boot ROM)
This is a 512 x 24-Bit factory programmed Boot ROM used for storing the program
sequence for initializing the DSP.
