- DSP56000 SIMULATOR
- Revision 1.11
-
- SIM56000.EXE is revision 1.11 of the DSP56000 simulator program. Revision
- 1.11 corrects a problem with the simulation of instructions of the type
- MOVE A,X0 #0,B that was discovered in revision 1.10 just prior to its release.
- The major changes from revision 1.0 are summarized below.
-
- The most significant change is that the simulator now simulates the DSP56001
- as a default. The internal bootstrap ROM and data ROM areas are predefined.
-
- The simulator has been enhanced to fully support long registers and long
- memory locations. The long memory is referenced using an L: prefix. The
- long registers are the Data Alu registers A, B, X, and Y. The X keycharacter
- in the DISPLAY and BREAK commands was changed to RW to avoid ambiguity with
- the X long register specification.
-
- Register and memory locations may now have an associated display radix. The
- associated radix is used when displaying the contents of the register or
- memory and during evaluation of expressions involving their contents. The
- RADIX command is used to specify the display radix.
-
- The DISASSEMBLE command has been enhanced so that consecutive entries of the
- command will page down through memory in 20 instruction blocks.
-
- The HELP command has been enhanced to allow help for register names. Bit
- field names are displayed along with the register contents for appropriate
- control and status registers.
-
- A new command, HISTORY, has been added which displays the previous 20
- instructions that executed prior to a breakpoint.
-
- Two major modifications were made to the INPUT and OUTPUT commands. The
- input and output radix can now be specified, simplifying the interface with
- other utilities that require floating point or decimal I/O. Peripheral pin
- bit stream input may now be tied to another device pin enabling, for example,
- the SCI RXD pin to receive input from the SCI TXD pin without intervening
- storage to a disk file.
-
- The simulation execution is now based on the device PLA contents, which
- enables excellent cycle by cycle correlation with the device operation.
