Hello TI' teams,
I found little difference between 2 documents that describes C67x megamodule on DM8148 processor.
tms320dm8148.pdf describe DSP and megamodule subsystem as:
The DSP Subsystem includes the following features:
• C674x DSP CPU
• 32KB L1 Program (L1P)/Cache (up to 32KB) with Error Detection Circuitry (EDC)
• 32KB L1 Data (L1D)/Cache (up to 32KB)
• 256KB Unified Mapped RAM/Cache (L2) with Error Correction Circuitry (ECC)
• Direct Connection to the HDVICP2 Host SL2 Port
• Little Endian
When DM8148 TRM (sprugz8e.pdf and sprufk5a.pdf) :
The C674x megamodule (Figure 1-7) consists of the following components:
• TMS320C674x CPU
• Internal memory controllers:
– Level 1 program memory controller (PMC)
– Level 1 data memory controller (DMC)
– Level 2 unified memory controller (UMC)
– Extended memory controller (EMC)
– Internal direct memory access (IDMA) controller
• Internal peripherals:
– Interrupt controller (INTC)
– Power-down controller (PDC)
– Bandwidth manager (BWM)
• Advanced event triggering (AET)...
And no any word about connect between c674x/L2 to HDVICP2.
C674x megamodule block diagram different too in TRM and in tms320DM8148.pdf - plz see attcahed images.
The difference: 256 bits bus "Direct Connection to the HDVICP2 Host SL2 Port".
Please let me known, what diagram is wrong?
