- version 2.0 05-02-96
- --------------------
- * Switched to bfd library. Any supported format (elf, coff, ...) can be used.
- * The UART devices can be set through -uart1 and -uart2 switches.
- * Switched to GNU readline.
- * Added -c option to run batch files at startup
- * 'reg' command can show different register windows (eg 'reg w3').
- * Use 'help' for online help on simulator commands
- version 1.8.1 20-01-96
- --------------------
- * added -mevrev0 switch to simulate MEC rev.0 bugs in timer and uart
- * added -iurev0 switch to simulate IU rev.0 jmpl/restore bug
- * Added sis command 'batch' to run batch files
- version 1.8 30-10-95
- --------------------
- * Added s-record support. Use the '-s' switch with sis or the 'load' command.
- * IU load dependencies are now modelled
- version 1.7 30-10-95
- --------------------
- * Power-down mode implemented in erc32.c.
-
- * Performance display shows the ratio between simulator-time and real-time.
- version 1.6.2 25-10-95
- --------------------
- * The UARTs can now be run at a given speed (simulator time) to better
- simulate the behaviour of interrupt routines. The "true mode" is
- selected through a compile switch in the makefile.
- version 1.6 28-09-95
- --------------------
- * Major reorganisation of the code. mec.c and mem.c merged into erc32.c.
- * The load command does NOT longer load the initialised data at an address
- defined by .bdata. This is done in srt0.s using _environ.
- * Additional MEC functionallity added - software reset, memory access
- protection and waitstate configuration register.
- * interf.c - a GDB interface added
- * -v switch (verbose) added
- version 1.5 14-09-95
- --------------------
- * Added a instruction trace buffer, enabled through the 'hist' command.
- * Added a 'perf' command to display statistics such as instruction mix,
- CPI, FPU holds etc.
- * Added -nfp switch to disable FPU.
- * Added -freq switch to set simulated frequency.
- version 1.4 22-08-95
- --------------------
- * A -g is provided for those who have problems with GNU readline().
- version 1.3 26-07-95
- --------------------
- * No major news, just a bug fix release ...
- version 1.2 13-07-95
- --------------------
- * Added setting of IU registers through the 'reg' command. See README.
- * The GNU readline() function is used for command input. However, a
- ctrl-D still kills the simulator ...
- version 1.1 07-07-95
- --------------------
- * Added a 'go' command
- * Added cycle counting for interrupt overhead.
- * Function 'get_mem_ptr' takes one more parameter to avoid segmentation
- faults if a.out files are loaded outside the simulated memory. See README.
- * Added user-defined function sim_stop().
- * Added a reset command. See README.
- * Implemented buffered output for MEC uarts to improve output speed.
