Almost 30. times faster than 80C51
24 times faster multiplication (12 times division)
DQ8051XP is an ultra high performance, speed optimized
soft core, of a single-chip 8-bit embedded control-ler, designed to operate with fast (typically on-chip) and slow (off-chip) memories. The core has been designed with a special concern about performance to power consumption ratio. This ratio is extended by an advanced power management PMU unit
. DQ8051XP soft core is 100% binary-compatible with the industry standard 8051 8-bit microcontroller. DQ8051 has built-in configurable DoCD-JTAG on chip debugger, supporting Keil µVision development platform and standalone DoCD debug software.<font color="blue"> Dhrystone 2.1 benchmark program runs from 19.69 to 26.62 times faster than the original 80C51 at the same frequency</font>
. This performance can also be exploited to great advantage in low power applications, where the core can be clocked over ten times more slowly, than the original implementation, for no performance penalty. DQ8051XP is fully customizable, which means, it is delivered in the exact configuration to meet your requirements. There is no need to pay extra, for not used features and wasted silicon.
The DQ8051XP is delivered with fully automated testbench and complete set of tests, allowing easy package validation, at each stage of SoC design flow.
Each of the DCD's 8051 Core has built in support for the DCD Hardware Debug System, called DoCDTM
. It is a real-time hardware debugger
, which provides debugging capability of a whole System on Chip (SoC).
Unlike other on-chip debuggers, the DoCDTM
provides non-intrusive debugging
of running application. It can halt, run, step into or skip an instruction, read/write any contents of microcontroller, including all registers, internal and external program memories and all SFRs, including user defined peripherals. More details about DCD on Chip Debugger
