Crossware Supports Silicon Laboratories' Mixed Signal MCUs

10/7/2004 - Crossware (, a leading embedded tools developer, has added full support to its 8051 Development Suite for the Silicon Laboratories ( C8051F12X and C8051F13X mixed signal microcontroller units (MCUs).

The Silicon Laboratories' chips feature advanced pipelining and caching and a phase locked loop which together allow the core to run at up to 100MIPS. A multiply and accumulate (MAC) engine can also perform a 16-bit signed multiplication in two cycles.

The Crossware enhancements allow developers to rapidly exploit the advanced features of these chips by providing a thorough combination of wizards, simulation, debugging, compiler extensions and pre-configuration. Code Creation Wizards are provided for all on-chip peripherals. They allow the phase locked loop to be rapidly configured to exploit the 100MIPS maximum performance and with the compiler and libraries using multiplication code that exploits the MAC engine, developers can instantly take full advantage of the speed offered by these chips.

The Crossware environment is fully pre-configured to take advantage of the MCU's 128k bytes of in-system programmable banked flash and when simulating and debugging the banking process is virtually transparent to the developer. In addition, the flash memory Code Creation Wizard will generate all the code necessary to erase and rewrite flash memory during program execution.

Crossware's source level debugger drives the Silicon Laboratories' JTAG emulation cartridge directly. This allows it to make use of the full range of on-chip debug facilities including the hardware data breakpoints and hardware stack overflow and underflow trap.

Crossware's 8051 development suite includes a full featured ANSI C compiler, a relocatable cross-assembler, an advanced overlay linker, a state of the art source level simulator that can be extended to simulate a complete target system and a debug monitor which supports source level debugging on the target system itself. All of these integrate into Crossware's Embedded Development Studio development environment to bring together the only single vendor tool set that can be used to develop and fully debug 8051 programmes both with and without hardware.
