mame/src/emu/cpu/mips/psx.c
Aaron Giles 04ae2d8bc7 Removed get context/set context calls from the CPU interface entirely. 
Pointer-ified the TMS99xx core (missed that one!)

/*
* PlayStation CPU emulator by smf
*
* Licensed to the MAME Team for distribution under the MAME license.
*
* Known chip id's
* CXD8530AQ
* CXD8530BQ
* CXD8530CQ
* CXD8661R
* CXD8606BQ
* CXD8606CQ
*
* The PlayStation CPU is based on the LSI LR33300.
*
* Differences from the LR33300:
*
* There is only 1k of data cache ram ( the LR33300 has 2k )
*
* There is no data cache tag ram, so the data cache ram can only be used as a fast area
* of ram ( which is a standard LR33300 feature ).
*
* If COP0 is disabled in user mode you get a coprocessor unusable exception, while
* the LR33300 is documented to generate a reserved instruction exception.
*
* Known limitations of the emulation:
*
* Only read & write break points are emulated, trace and program counter breakpoints are not.
*
* Load/Store timings are based on load scheduling turned off & no write cache. This affects when
* bus error exceptions occur and also when the read & write handlers are called. A scheduled
* load will complete if a load breakpoint fires, but an unscheduled load will not.
*
* Reading from the data and instruction cache at the same time causes a bus conflict that
* corrupts the data in a reliable but strange way, which is not emulated.
*
* Values written to COP1 & COP3 can be read back by the next instruction, which is not emulated.
* Because of loadscheduling the value loaded with LWC1/LWC3 can be read by more than the next
* instruction.
*
* SWC0 writes stale data from a previous operation, this is only partially emulated as the timing
* is complicated. Left over instruction fetches are currently emulated as they are the most
* 'interesting' and have no impact on the rest of the emulation.
*
* MTC0 timing is not emulated, switching to user mode while in kernel space continues
* execution for another two instructions before taking an exception. Using RFE to do the same
* thing causes the exception straight away, unless the RFE is the first instructio that follows
* an MTC0 instruction.
*
* The PRId register should be 1 on some revisions of the CPU ( there might be other values too ).
*
* Moving to the HI/LO register after a multiply or divide, but before reading the results will
* always abort the operation as if you did it immediately. In reality it should complete on it's
* own, and aborting before it completes would result in returning the working results.
*
* Running code in cached address space does not use or update the instruction cache.
*
* Wait states are not emulated.
*
* Bus errors caused by instruction fetches are not supported.
*
