SUNNYVALE, CA. (AUGUST 22, 2002) - Marvell Technology Group Ltd. (NASDAQ: MRVL),
a technology leader in the development of extreme broadband communications

Net revenue for the second quarter of fiscal 2003 was a record $119.7 million,
an increase of 74% over net revenue of $68.7 million for the second quarter of
fiscal 2002 and a 21% sequential increase from net revenue of $98.8 million for
the first quarter of fiscal 2003. Net loss under generally accepted accounting
principles (GAAP), which includes the effect of acquisition-related expenses and
the amortization of stock-based compensation was $9.3 million, or $0.08 per
share (diluted), for the second quarter of fiscal 2003, compared with net loss
under GAAP of $105.2 million, or $0.93 per share (diluted), for the second
quarter of fiscal 2002.

Net revenue for the six months ended August 3, 2003 was $218.5 million, an
increase of 64% over net revenue of $132.9 million for six months ended July 28,
2001. Net loss under GAAP was $40.3 million, or $0.34 per share (diluted), for
the six months ended August 3, 2002, compared with net loss under GAAP of $210.2
million, or $1.86 per share (diluted), for the six months ended July 28, 2001.

Pro forma net income, which excludes the effect of acquisition-related expenses,
amortization of stock-based compensation and a special charge related to
facilities consolidation in the first quarter of fiscal 2003, was $14.2 million,
or $0.11 per share (diluted), for the second quarter of fiscal 2003, compared
with pro forma net income of $3.4 million, or $0.03 per share (diluted), for the
second quarter of fiscal 2002. Pro forma net income was $24.7 million, or $0.19
per share (diluted), for the six months ended August 3, 2002, compared with pro
forma net income of $7.9 million, or $0.06 per share (diluted), for the six
months ended July 28, 2001.

"We are experiencing strength across both our data storage and data
communications businesses," stated Dr. Sehat Sutardja, Marvell's President and
CEO. "The 21% sequential increase in our quarterly revenue was largely driven by
the continued adoption of Gigabit Ethernet to the desktop and our integrated
system-on-chip storage solutions. Bookings during the quarter continued to be
strong resulting in record backlog at the end of the quarter. We also continue
to experience strong design activity with our Serial ATA solutions, Libertas(TM)
wireless LAN products, and Prestera(TM) family of Gigabit Ethernet switches."

Marvell's Chief Executive Officer and Chief Financial Officer will certify the
Company's financial statements, as required by the Sarbanes-Oxley Act of 2002,
in connection with the filing of the Company's Form 10-Q on or before its due
