TDEA core for interoperability with legacy payment and smart card systems.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| data_in | in | AXI4-Stream | 64 | |
| data_out | out | AXI4-Stream | 64 |
Standards
- NIST SP 800-67 Rev. 2
- ISO/IEC 18033-3
Notes
NIST disallowed TDEA for encryption after 2023; offered for decryption and legacy interoperability only.
