1.2. Product revisions

This section describes the differences in functionality between product revisions of the CoreLink SIE-200 System IP for Embedded:


First release.


Second release. Functional improvement to AMBA® AHB5 downsizer.


Third release. Added the following:

  • AHB5 example slave.

  • AHB5 GPIO.

  • AHB5 timeout monitor.

  • AHB5 to external SRAM interface.

  • AHB5 to ROM interface.

  • Cortex-M3/Cortex-M4 AHB5 adapter.

  • Behavioral SRAM model with an AHB5 interface.

  • External asynchronous 8-bit SRAM model.

  • External asynchronous 16-bit SRAM model.

  • FPGA SRAM synthesizable model.

  • RAM wrapper model.

  • ROM behavioral model.

  • ROM wrapper model.


Fourth release. Added the following:

  • ABHB5 to AHB5 low-latency sync-down bridge.

  • AHB5 to AHB5 low-latency sync-up bridge.

  • ABH5 to APB4 low-latency sync-down bridge.


The low-latency bridges in release r3p0 are similar in function to their non-low-latency equivalents. They are options for designs that do not require Q-channel support for power management.

This option enables optimization for reduced latency in these three bridges.
