Don't worry, they're going to have to release it again. This zip contains many files with copyright (c) Broadcom (and other companies) missing the 3-clause BSD

  Looks like SSE2 or SSE3 with a different syntax and vector support.

  The vector register file is a block of registers 64 bytes across by 64 down which can be accessed horizontally (H) or vertically (V), and in units of 16 bytes (H8), 16 shorts (H16 or HX), or 16 32-bit words (H32). Each processor has an accumulator that can be cleared (CLRA) or used (ACC). This code is basically equivalent to the following C code: uint8 in[2][16]; int16 temp[2][16]; int32 r1,r3,r5; uint8 *r0; do { ... code omitted // vmul -,H(1,0),3 CLRA ACC // vadd HX(3,0),H(0,0),2 ACC for(x=0;x<16;x++) { temp[x]=inb[1][x]*3+in[0][x]+2; } //vasr H(0++,0),HX(2++,0),2 REP 2 //vst H(0++,0),(r0+=r3) REP 2 for(y=0;y<2;y++) { for(x=0;x<16;x++) { in[y][x] = temp[y][x]>>2; r0[y*r3+x] = in[y][x]; } } // add r0,16 // addcmpblt r5,1,r1,loopacross r0 += 16; r5 += 1; } while (r5<r1); This is code for the vector processor. This is not the same as the GPU cores which use a different architecture and instruction set (based around floating point calculations).

    I made a back of the envelop design of a arch that used the same technique in college. Way cool to see it in practice. This project of yours look really cool, https://github.com/peterderivaz/pymeta3 https://github.com/peterderivaz/pymeta3 What do you think about http://www.myhdl.org/doku.php http://www.myhdl.org/doku.php ?

    Fancy meeting you here :)

    Wow, a selectable row-major or column-major register file! I would have never imagined such a thing. =)

  What/where is the assembler thar is used compile this code?
