  • Unit-00: ScaleTableMatrix 8x8 (32 registers per 26 bits) used as 64 records per 13bits.
  • Unit-01: IDCT intermediate result (13 vertical, 16 horizontal, 16 x 13-bit words, separate IO)
  • Unit-02 (56 vertical, 8 horizontal)
  • Unit-03
  • Unit-04 (32 vertical, 16+32+16 horizontal)
  • Unit-05 (24 vertical, 16+32+16 horizontal)
  • Unit-20 (16 vertical, 16+32+16 horizontal)

Dual port registers:
