b73727596f Remove loadInstructionFast as it's the same as loadU32fast. 2024-01-07 10:13:10 +00:00

cd42f25798 Use Uint8Array for CPU1 register index lookup tables. 
Performance seems the same as Uint32Array but this will help reduce data cache usage.

804292cb1b Avoid a little overhead with instruction fetches by caching the DataView. 2024-01-07 10:13:10 +00:00

4c89533028 Implement RSP PC as a regular member variable rather than using a DataView. 
Instead have SPIBIST device read/write this value directly.

This ends up saving quite a lot of overhead in step().

85dc4ffd23 Remove all the signed versions of memory read accessors and just do this as needed in memaccess. 
This avoids a lot of duplication and opportunities for bugs (e.g. failing to override correctly)

d14f0ff852 Fix bug in runImpl which was preventing backwards branches from being detected and therefore rendering dynarec inert most of the time. 
`pc` was being converted to a signed value for fast memory accesses, but was being compared to an unsigned value for backwards branch detection.

0995959cfc Optimise RSP accumulator. 
The BigInt conversions are very expensive so implement 64-bit integer addition by hand.

This is about 10-20x faster according to the benchmark.

af1a1148d6 Fix RSP jumps to 0x1000. 
Due to the masking these jumps were being silently ignored. Among other things this broke perspective divide for GBI0 microcode, which call this function at 0x1000.

e5509d1f53 Fix VSAR for the default case. 
When the accumulator value is signed this was producing values of -1 rather than 0.

b48f2a06eb Add a RDPBuffer helper. 
This hides a bit of the complexity of needing to wrap around DMEM. Still needs some work.
