Question: Who was involved in designing a processor that is manufactured by Samsung?
Context: Jim Keller is a microprocessor engineer most well known for his work at AMD and Apple.  He was the lead architect of the AMD K8 microarchitecture (including the original Athlon 64) and was involved in designing the Athlon (K7) and Apple A4/A5 processors.  He was also the coauthor of the specifications for the x86-64 instruction set and HyperTransport interconnect.  From 2012 to 2015, he returned to AMD to work on the AMD K12 and Zen microarchitectures. The Apple A4 is a 32-bit package on package (PoP) system-on-a-chip (SoC) designed by Apple Inc. and manufactured by Samsung.  It combines an ARM Cortex-A8 CPU with a PowerVR GPU, and emphasizes power efficiency.  The chip commercially debuted with the release of Apple's iPad tablet; followed shortly by the iPhone 4 smartphone, the iPod Touch (4th generation), and the Apple TV (2nd generation).  It was superseded by the Apple A5 processor used in the iPad 2 released the following year, which was then subsequently replaced by the Apple A5X processor in the iPad (3rd generation). The Samsung Galaxy Pocket Plus is an Android smartphone manufactured by Samsung that was released in January 2013 as the successor to the original Samsung Galaxy Pocket.  The handset is still budget-oriented, with a relatively small 2.8-inch LCD.  Its specifications are similar to that of the original Samsung Galaxy Pocket, with only minor upgrades such as the OS which is Android 4.0 ICS and the internal storage.  The Pocket Plus is powered by an 850 MHz processor and offers connectivity options including 3G, Wi-Fi and Bluetooth 4.0.  Internally, it comes with an upgraded 4 GB of storage which can be further expanded to up to 32 GB using a microSD card, and with 1200 mAh Li-ion battery. The Samsung Galaxy A8 (2016) (stylized as SAMSUNG Galaxy A8) is an Android phablet produced by Samsung Electronics.  It was introduced on September 30, 2016 by South Korean telecom provider SK Telecom.  Unlike most Galaxy A series smartphones, the Galaxy A8 (2016) provides with a better processor similar to Samsung's 2015 flagships, the Samsung Galaxy S6, Samsung Galaxy S6 Edge and Samsung Galaxy Note 5. The Samsung Galaxy Ace (also known as Samsung Galaxy Cooper in some territories) is a smartphone manufactured by Samsung that runs the open source Android operating system.  Announced and released by Samsung in February 2011, the Galaxy Ace features an 800 MHz Qualcomm MSM7227 processor with the Adreno 200 GPU.  It is available in black, with back covers in three different colors: black, purple and white. The Samsung Galaxy Pocket Neo is an Android smartphone manufactured by Samsung that was released in June 2013 as the successor to the Samsung Galaxy Pocket Plus.  The handset is still budget-oriented, sporting a larger 3-inch LCD.  Its specifications are similar to that of the Samsung Galaxy Pocket Plus, with only minor upgrades such as the OS which is Android 4.1.2 Jelly Bean and the screen size.  The Pocket Neo is powered by an 850 MHz processor and offers a set of connectivity options including 3G, Wi-Fi and Bluetooth 4.0.  Internally, it comes with 4 GB of storage which can be further expanded to up to 32 GB using a microSD card, and with 1200 mAh Li-ion battery. The Samsung Galaxy Core 2 is a smartphone manufactured by Samsung Electronics.  It was first unveiled by Samsung in June 2014 on the official website and was released the following month.  It is the successor to the Samsung Galaxy Core.  It runs on Android 4.4.2 KitKat.  It has a 4.5 inch capacitive touchscreen with WVGA (480x800) resolution, with a pixel density of 207 ppi.  It has a Quad-core processor clocked at 1.2 GHz.  It has 768 MB of RAM.  The Galaxy Core 2 has 4GB of internal storage and supports MicroSD cards up to 64GB. The Samsung Galaxy Tab 8.9 is an Android-based tablet computer designed and manufactured by Samsung, introduced on 22 March 2011 at CTIA wireless convention in its Samsung Unpacked event in Orlando.  It is part of the Samsung Galaxy Tab series, and features an 8.9-inch display and a 1 GHz dual-core Nvidia Tegra 2 processor. The Samsung Galaxy Spica, also known as Samsung Spica, Samsung GT-I5700, Samsung Galaxy Lite and Samsung Galaxy Portal, is a smartphone manufactured by Samsung that uses the open source Android operating system.  The phone is referred to as the successor of the Samsung i7500 and sometimes referred as Galaxy Lite.  Even though some of its features like the camera resolution, storage and data connection speeds are lower than the i7500 its processor's clock speed is much higher at 800 MHz.  It is succeeded by the Samsung Galaxy 3. The Saturn family of 4-bit microprocessors was developed by Hewlett-Packard in the 1980s for programmable scientific calculators/microcomputers.  It succeeded the "Nut" family of processors used in earlier calculators.  The original Saturn chipset was first used in the HP-71B hand-held BASIC-programmable computer, introduced in 1984.  Later models of the family powered the popular HP 48 series of calculators, among others.  The HP 49 series initially used the Saturn CPU as well, until the NEC fab could no longer manufacture the processor for technical reasons in 2003.  Therefore, starting with the HP 49g+ model in 2003, the calculators switched to use a Samsung S3C2410 processor with ARM920T core (part of the ARMv4T architecture) to run an emulator of the Saturn architecture in software.  In 2000, the HP 39G and HP 40G were the last calculators introduced based on the Saturn hardware.  The last calculators based on the Saturn emulator were the HP 39gs, HP 40gs and HP 50g in 2006, as well as the 2007 revision of the hp 48gII.  The HP 50g, the last calculator utilizing this emulator, was discontinued in 2015 when Samsung stopped producing the ARM processor it was based on.
