ITEM 7.  Financial Statements and Exhibits

         (c) Exhibits.

             99.1     Press release, dated April 15, 2004, reporting financial
                      results of PMC-Sierra, Inc. (the "Registrant") for its
                      fiscal first quarter ended March 28, 2004 (furnished and
                      not filed herewith solely pursuant to Item 12).



ITEM 12. Results of Operations and Financial Condition

         On April 15, 2004, the Registrant issued a press release reporting the
financial results for its fiscal first quarter ended March 28, 2004. The press
release is attached hereto as Exhibit 99.1 and incorporated by reference herein.

         The information in this Form 8-K and the Exhibit, attached hereto,
shall not be deemed to be "filed" for purposes of Section 18 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to
the liabilities of that section, nor shall it be deemed incorporated by
reference in any filing under the Securities Act of 1933, as amended, or the
Exchange Act, regardless of any general incorporation language in such filing.

         As a supplement to the Registrant's consolidated financial statements
presented on a generally accepted accounting principles (GAAP) basis, the
Registrant provides additional non-GAAP measures for income (loss) from
operations, net income (loss) and net income (loss) per share in its press
release.

         A non-GAAP financial measure is a numerical measure of a company's
performance, financial position, or cash flows that either excludes or includes
amounts that are not normally excluded or included in the most directly
comparable measure calculated and presented in accordance with GAAP. The
Registrant believes that the additional non-GAAP measures are useful to
investors for the performance of financial analysis. Management uses these
measures internally to evaluate its in-period operating performance and the
measures are used for planning and forecasting of the Registrant's future
periods. However, non-GAAP measures are not in accordance with, nor are they a
substitute for, GAAP measures. Other companies may use different non-GAAP
measures and presentation of results.












                                    SIGNATURE

         Pursuant to the requirements of the Securities Exchange Act of 1934,
the registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.


                                            PMC-SIERRA, INC.
