A method and apparatus for performing compression comprises a system having a buffer, a wavelet transform unit, and a coder. The wavelet transform unit has an input coupled to the buffer to perform a wavelet transform on pixels stored therein and to generate coefficients at an output. The coder is coupled to the wavelet transform unit to code bitplanes of wavelet transformed pixels received from the wavelet transform unit, and stored bitplanes of wavelet transformed pixels received from the buffer. |
