Digital Core Design


DCD (Digital Core Design) provides VHDL- and Verilog-synthesizable, ISO 9001:2000-certified IP (intellectual-property) cores of 8-, 16-, and 32-bit processors and bus interfaces, as well as fixed- and floating-point arithmetic coprocessors. DCD's DP8051XP/DP80390XP soft core is 100%-binary-compatible with the industry-standard, 8-bit 8051 microcontroller. Its SXDM (synchronous-external-data-memory) interface enables fast access to external data memory. DP8051XP/DP80390XP's dual data pointers have automatic-increment, -decrement, and -switching capabilities, significantly speeding memory operations. DCD's microcontrollers implement fast, 16- and 32-bit integer operations and single- and double-precision floating-point operations. The D68HC11 is fully compatible with the 68HC11A and 68HC11E.
