Most powerful mini-8051?

Polish IP firm Digital Core Design has put an 8051 CPU into under 3,000 asic gates, claiming it to be the most powerful at this size. "A very low gate count area allows as well to run the core at high performance, up to 300MHz in Hynix 0.18µm library, equivalent performance to the original 80C51 clocked with 2.4GHz", said DCD. Fellow Polish firm Evatronix has been offering T8051 , a 2,700 gate 8051 , since 2009. With DCD's DT8051 "The complete system with peripherals and the debugger needs just 6,650 asic gates," said the firm. "Regarding 32bit ARM cores, when even a plain M0 uses more than 10,000 gates." The soft core is 100% binary-compatible with the industry standard 8051, said DCD and Dhrystone 2.1 benchmarking indicates that it is 8.1x faster than the original 80C51 at the same frequency. "The performance results are more than 2 times higher than the nearest competit...
