World’s Fastest 8051 CPU: Quad-Pipelined Microcontroller IP Core

Digital Core Design announced the DQ80251 Core. It is a quad-pipelined, speed optimized soft core of a 16-bit/32-bit embedded microcontroller. The DCD DQ80251 IP core is the world’s fastest 8051 microprocessor solution. With a confirmed Dhrystone 2.1 benchmark, the DQ80251 IP core is up to 56.8 times faster than the original 8051 and 4.81 times faster than the original 80C251 at the same clock frequency. The DQ80251 includes a fully automated testbench and a complete set of tests.

Digital Core Design (DCD) DQ80251 Microcontroller IP Core

The DQ80251 soft core is 100% binary-compatible with the 16-bit 80C251 and 8-bit 80C51 microcontrollers. There are two working modes of the DQ80251: BINARY (where original 80C51 compiled code is executed) and SOURCE (native 80C251 mode with DQ80251 performance). DQ80251 has a built-in, configurable DoCD-JTAG on chip debugger, which supports Keil DK251 and standalone DoCD debug software.
