Criticism
Register windows are not the only way to improve register performance. The group at Stanford University designing the MIPS architecture saw the Berkeley work and decided that the problem was not a shortage of registers, but poor utilization of the existing ones. They instead invested more time in their compiler's register allocation, making sure it wisely used the larger set available in the MIPS instruction set. This resulted in reduced complexity of the chip, with one half the total number of registers, while offering potentially higher performance in those cases where a single procedure could make use of the larger visible register space. In the end, with modern compilers, the MIPS design makes better use of its register space even during procedure calls.

Famous quotes containing the word criticism:
“Unless criticism refuses to take itself quite so seriously or at least to permit its readers not to, it will inevitably continue to reflect the finicky canons of the genteel tradition and the depressing pieties of the Culture Religion of Modernism.”
—Leslie Fiedler (b. 1917)
“Good criticism is very rare and always precious.”
—Ralph Waldo Emerson (1803–1882)
“To be just, that is to say, to justify its existence, criticism should be partial, passionate and political, that is to say, written from an exclusive point of view, but a point of view that opens up the widest horizons.”
—Charles Baudelaire (1821–1867)
