Table 9-7 summarizes the SIMCOP high-level interrupts mapped to the outer boundaries of the SIMCOP. For more information about interrupts generated from inside the SIMCOP modules, see Section 9.4, ISS Still Image Coprocessor.
| Event and Register | Description |
|---|---|
| SIMCOP_HL_IRQENABLE_SET_i[19] CPU_PROC_START_IRQ | Interrupt used when CPU data processing is used in a macroblock processing pipeline. When the CPU receives this IRQ, data is ready to be processed. When the CPU finishes processing the data, it acknowledges by setting the SIMCOP_HWSEQ_CTRL.CPU_PROC_DONE bit. |
| SIMCOP_HL_IRQENABLE_SET_i[18] SIMCOP_DMA_IRQ1 | Interrupt triggered by SIMCOP DMA |
| SIMCOP_HL_IRQENABLE_SET_i[16] OCP_ERR_IRQ | SIMCOP master port interface error |
| SIMCOP_HL_IRQENABLE_SET_i[14] DONE_IRQ | Event triggered when hardware sequencer finishes the sequence:
|
| SIMCOP_HL_IRQENABLE_SET_i[13] STEP3_IRQ | Event triggered when a SIMCOP Context 3 is activated by the hardware sequencer. |
| SIMCOP_HL_IRQENABLE_SET_i[12] STEP2_IRQ | Event triggered when a SIMCOP Context 2 is activated by the hardware sequencer. |
| SIMCOP_HL_IRQENABLE_SET_i[11] STEP1_IRQ | Event triggered when a SIMCOP Context 1 is activated by the hardware sequencer. |
| SIMCOP_HL_IRQENABLE_SET_i[10] STEP0_IRQ | Event triggered when a SIMCOP Context 0 is activated by the hardware sequencer. |
| SIMCOP_HL_IRQENABLE_SET_i[9] LDC_BLOCK_IRQ | A macroblock has been processed. |
| SIMCOP_HL_IRQENABLE_SET_i[1] LDC_FRAME_IRQ | A full frame has been processed. |
| SIMCOP_HL_IRQENABLE_SET_i[0] SIMCOP_DMA_IRQ0 | Interrupt triggered by SIMCOP DMA |
