Digital Core Design is claiming the fastest 8051 processor core implementation.
According to the Poland-based silicon IP design house, claims independent tests, carried out on Dhrystone 2.1 benchmark programme, which is representative of general processor (CPU) performance, showed the DQ80251 quad-pipelined IP Core was 56.8 times faster than the original 8051 at the same clock frequency.
"Our DQ80251 runs at 300MHz without losing's breath. It was possible not because of adding higher frequency, but thanks to unique architecture we implemented," said Thomas Krzyzak, v-p at Digital Core Design.
"An original 8051, to get equivalent performance, must be clocked with 17,000 MHz ," said Krzyzak.
The core provides up to 0.54311 DMIPS/MHz (VAX MIPS) and uses only 14,500 Asic gates.
DQ80251 family provides real-time JTAG-based DoCD debugger and is fully user configurable.
DCD’s DQ80251 family is available as VERILOG Source code, VHDL Source code and FPGA Netlist formats.
