| 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. | |
