MSC8144E SC3400 DSP Subsystem
10
Each SC3400 core is embedded in an DSP subsystem that enhances the power of the SC3400
core and provides a simple interface to each SC3400 core. The DSP core subsystem includes:
SC3400 core
Internal memory subsystem:
— Memory management unit (MMU)
— Instruction channel and L1 Instruction cache (16 KB, 8-way)
— Data channel, Data cache (32 KB, 8-way), and write queue
Interrupt processing using the Embedded Programmable Interrupt Controller (EPIC)
Real-time debug support with a JTAG controller and test access port (TAP), on-chip
emulator (OCE), and debug and profiling unit (DPU)
Dual timer
Two interfaces (instruction and data) to link the QBus structure supported by the SC3400
core with the MBus used to interface with the other functional blocks in the MSC8144
device
Five operating states including two core power saving modes
Note:
The SC3400 DSP Core Reference Manual and the MSC8144 SC3400 DSP Core
Subsystem Reference Manual have detailed information on the DSP core and core
subsystem. Both manuals are available with a signed non-disclosure agreement.
Contact your local Freescale dealer or sales representative for more information.
