B.4. Custom IP

The IP listed in Table B.4 is created specifically for the ARM1176JZF Development Chip.

Table B.4. Custom IP descriptions

IP ProductDescription
System controller

APB peripheral.

See Chapter 3 Programmer’s Model.

Dynamic Clock Generator (DCG)

Custom clock generator.

See Intelligent Energy Management (IEM).

AXI ID merge block, Axi64IdMerge

Block created to reduce eight ID bits to six to:

  • Make better use of PL340 Quality of Service (QoS)

  • Reduce maximum ID width in SoC, the L2CC configuration port can only accept eight ID bits. Cascaded AXI blocks require nine bits.

  • Reduce ID bit width on AXI master port.

See Chapter 2 Functional Overview.

Ring oscillators, RingOscGateRing oscillators created from gate delay elements to measure voltage in Vsoc and Vcore domains.
SoC Configuration Capture Block, SoCConfig

SOC Config block added custom code.
