Other project properties
Development status: Stable
Design done, FPGA proven
WishBone Compliant: Yes
Interface an 8051-compatible microcontroller with the Wishbone bus.
- Multiplexed 8051 address/data bus to Wishbone Master
- Very simple, very small.
- Since 8051 has no way to add additional wait-states via an external pin, the Wishbone must be fast enough to complete the cycle in time for the 8051.
- Tested with Silicon Labs C8051 Microcontroller and Xilinx Coolrunner2 CPLD.
- Tested with Silicon Labs C8051 Microcontroller and Xilinx Spartan3 FPGA.
- this core is used in the Altair32 Front Panel: www.altair32.com
