Hi,
We at HCL Technologies Pvt. Ltd. Have ported binutils v1.5 for the MAXQ
architechture.
MAXQ is a new high performance RISC architecture from Maxim Integrated
Products & Dallas Semiconductor.
The MAXQ RISC architecture has a new microcontroller core that combines
high performance and low power
with a variety of complex analog functions.
The MAXQ can be seen as a MOVE driven architecture and the source and
destination operands for the
"MOVE" instruction are the basis for creating instructions and memory
accesses, and triggering hardware
operations.

Initially the MAXQ Arch. has two slightly different versions named
MAXQ10 and MAXQ20. The primary
difference between the MAXQ10 and MAXQ20 options is the standard width
of the working accumulators
and supporting arithmetic logic unit (ALU). The MAXQ10 supports 8-bit
(byte-wide) accumulators and
ALU operations, while the MAXQ20 supports 16-bit (word-wide)
accumulators and ALU operations.
The MAXQ microcontroller uses Peripheral Registers to control and
monitor peripheral
modules (like General Purpose I/O Module, UART, MAC etc.)

About MAXQ binutils v2.15 port
------------------------------
- The binutils contains support for both MAXQ10 and MAXQ20 versions of
MAXQ.
- Apart from standard MAXQ Arch. binutils support the MAXQ2000
variant. Which includes support for
integrated, in-system-programmable flash memory and a wide range of
peripherals including an LCD
driver supporting up to x4 multiplexed displays. The MAXQ2000 is
ideally suited for battery-powered,
portable applications such as blood glucose monitoring, medical
instrumentation, environmental data logging, and industrial control.
Testing binutils for MAXQ
-------------------------
The testcases for the MAXQ arch. has been integrated into the DEJAGNU
Testsuite.
which will be posted later on.
Configuring and Installing
--------------------------
While configuring the binutils source we need to specify the option
'--enable-bfd-assembler'.
Go to the binutils sources and do:
> configure --enable-bfd-assembler --target=maxq-coff
> make
> make install
