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. + |
