DSP56367 Overview
DSP56300 Core Functional Blocks
•
On-chip memory-expandable hardware stack
•
Nested hardware DO loops
•
Fast auto-return interrupts
The PCU implements its functions using the following registers:
•
PC—program counter register
•
SR—Status register
•
LA—loop address register
•
LC—loop counter register
•
VBA—vector base address register
•
SZ—stack size register
•
SP—stack pointer
•
OMR—operating mode register
•
SC—stack counter register
The PCU also includes a hardware system stack (SS).
1.4.4
INTERNAL BUSES
To provide data exchange between blocks, the following buses are implemented:
•
Peripheral input/output expansion bus (PIO_EB) to peripherals
•
Program memory expansion bus (PM_EB) to program memory
•
X memory expansion bus (XM_EB) to X memory
•
Y memory expansion bus (YM_EB) to Y memory
•
Global data bus (GDB) between registers in the DMA, AGU, OnCE, PLL, BIU, and
PCU as well as the memory-mapped registers in the peripherals
•
DMA data bus (DDB) for carrying DMA data between memories and/or peripherals
•
DMA address bus (DAB) for carrying DMA addresses to memories and peripherals
•
Program Data Bus (PDB) for carrying program data throughout the core
•
X memory Data Bus (XDB) for carrying X data throughout the core
•
Y memory Data Bus (YDB) for carrying Y data throughout the core
