5 * Switched to bfd library. Any supported format (elf, coff, ...) can be used.
6 * The UART devices can be set through -uart1 and -uart2 switches.
7 * Switched to GNU readline.
8 * Added -c option to run batch files at startup
9 * 'reg' command can show different register windows (eg 'reg w3').
10 * Use 'help' for online help on simulator commands
12 version 1.8.1 20-01-96
15 * added -mevrev0 switch to simulate MEC rev.0 bugs in timer and uart
17 * added -iurev0 switch to simulate IU rev.0 jmpl/restore bug
19 * Added sis command 'batch' to run batch files
25 * Added s-record support. Use the '-s' switch with sis or the 'load' command.
27 * IU load dependencies are now modelled
32 * Power-down mode implemented in erc32.c.
34 * Performance display shows the ratio between simulator-time and real-time.
37 version 1.6.2 25-10-95
40 * The UARTs can now be run at a given speed (simulator time) to better
41 simulate the behaviour of interrupt routines. The "true mode" is
42 selected through a compile switch in the makefile.
48 * Major reorganisation of the code. mec.c and mem.c merged into erc32.c.
50 * The load command does NOT longer load the initialised data at an address
51 defined by .bdata. This is done in srt0.s using _environ.
53 * Additional MEC functionallity added - software reset, memory access
54 protection and waitstate configuration register.
56 * interf.c - a GDB interface added
58 * -v switch (verbose) added
63 * Added a instruction trace buffer, enabled through the 'hist' command.
65 * Added a 'perf' command to display statistics such as instruction mix,
68 * Added -nfp switch to disable FPU.
70 * Added -freq switch to set simulated frequency.
75 * A -g is provided for those who have problems with GNU readline().
80 * No major news, just a bug fix release ...
86 * Added setting of IU registers through the 'reg' command. See README.
88 * The GNU readline() function is used for command input. However, a
89 ctrl-D still kills the simulator ...
96 * Added a 'go' command
98 * Added cycle counting for interrupt overhead.
100 * Function 'get_mem_ptr' takes one more parameter to avoid segmentation
101 faults if a.out files are loaded outside the simulated memory. See README.
103 * Added user-defined function sim_stop().
105 * Added a reset command. See README.
107 * Implemented buffered output for MEC uarts to improve output speed.
