Keil C51 v7.50 Supports Mentor M8051EW
Plano, TX: Keil Software today announced the C51
Development Suite Version 7.50 has been updated with full support
(including device simulation) for the memory expansion of the Mentor
M8051EW 8-bit Soft Core. The M8051EW is a complete high
performance 8051 IP core that offers several extended features
including:
-
High-speed, 2-cycle 8051 CPU core with wait-state support for
slow program and external data memory.
-
Up to 1 MByte RAM or ROM, accessible by a choice of
interfaces.
- 8052-compatible peripheral set including UART and timers.
-
Flexible Interrupt controller, up to 15 sources, and 4 priority
levels.
- Instruction extension for Flash ROM programming.
The M8051EW Product Datasheet is available at: www.mentor.com/inventra/cores/catalog/prod_desc/m8051ew_pd.pdf.
Keil Software supports the M8051EW Memory Extension via specific
linker directives and a Memory Extension Configuration File. The
M8051EW memory interface may be used for Program Code, Constant, and
Data Memory Extensions. Detailed information is provided in Application Note
171: Using M8051EW Memory Extension.
The µVision
Debugger / Simulator includes complete, timing-accurate
simulation of all M8051EW core peripherals.
Now in Version 7.50, the uVision Debugger even simulates the memory
extension registers and multiple DPTR. This core peripheral
simulation may be expanded with user specific extensions using the
Advanced Generic Simulation Interface (AGSI) of the µVision
Simulator. Examples for such extensions are provided in Application Note
154: Implementing DLLs for User-defined Simulation (AGSI).
Silicon designers can avoid costly chip re-designs by using the AGSI
to evaluate the performance of their peripheral designs while
simultaneously providing debugging support for software
engineers.
The Keil PK51
Professional Developer's Kit offers complete development tool
support for the user's of M8051EW-based devices.
Simulation allows software testing without hardware, provides fast
edit-compile-test cycles, improves product quality, and enables
reproducible regression test results.
