The L1P memory detection logic (no correction is implemented) uses a 4-bit parity per 256-bit location (1-bit parity per 64-bit line quadrant).
The L1P error detection logic features:
The L1P parity error detection event is exported outside the DSP C66x CorePac in the subsystem, and can be enabled to trigger the ERRINT_IRQ aggregated interrupt output. See also corresponding "PMC_ED" event in the Table 5-5.
The L1P error detection event is not exported outside DSP subsystem. However it is merged (OR-ed) along with other error event sources within the DSP subsystem to produce a single ERRINT_IRQ interrupt exported outside the DSP subsystem.
For more details on ERRINT_IRQ generation and asscoiated event registers at DSP_SYSTEM level, refer to the Section 5.3.4.2.2.
