8051 IP Core – Release 1.6

Today Oregano Systems published the release 1.6 of its popular 8051 IP core. The Oregano Systems 8051 IP core is available for free under LGPL license.


This new release 1.6 resolves three issues found in the past years:


  • CJNE commands did not properly handle the CARRY flag
  • The stackpointer had been corrupted with a sequence of RETI and RET commands
  • SIU interpreted stop bits in a wrong way

Please send us your comments on this new release.


Special thanks goes to our colleagues at Fachhochschule Technikum Wien, Fachbereich Embedded Systems. They supported Oregano Systems in identifying and fixing these issues.
