Am2900 is a family of integrated circuits (ICs) created in 1975 by Advanced Micro Devices (AMD). They were constructed with bipolar devices, in a bit-slice topology, and were designed to be used as modular components each representing a different aspect of a computer control unit (CCU). By using the bit slicing technique, the Am2900 family was able to implement a CCU with data, addresses, and instructions to be any multiple of 4 bits by multiplying the number of ICs. One major problem with this modular technique was that it required a larger number of ICs to implement what could be done on a single CPU IC. The Am2901 chip was the arithmetic logic unit (ALU), and the "core" of the series. It could count using 4 bits and implement binary operations as well as various bit-shifting operations.

Obvody pro řezový procesor využívající bipolární technologii byly navrženy jako modulární součásti, z nichž každá měla reprezentovat jiný aspekt řadiče (Computer Control Unit zkráceně CCU). Díky technologii bit slicing (doslova „krájení po bitech“) byly obvody řady 2900 schopny implementovat řídicí jednotky s daty, adresami a instrukcemi, jejichž bitová šířka mohla být jakýkoli násobek 4 bitů kaskádováním těchto obvodů. Jedním hlavním problémem s touto modulární technikou byl větší počet požadovaný obvodů, který by jinak zastal jeden procesor. Základním obvodem této série byla aritmeticko-logická jednotka Am2901, případně její novější revize.

(en) Am2900 ist eine 1975 von Advanced Micro Devices (AMD) eingeführte Familie von Bit-Slice-Bausteinen. Diese waren dazu gedacht, sich nach dem Konzept des Bit-Slicing eine mikroprogrammierbare CPU nach eigenen Bedürfnissen frei zusammenzustellen. Der Am2901-Chip war als arithmetisch-logische Einheit (ALU) der „Kern“ der Serie. Er konnte auf 4 Bit rechnen und binäre Operationen sowie diverse Schiebeoperationen ausführen. Mit dem Am2902, einem Carry-Look-Ahead-Baustein, und dem Am2904-Wortrand-Baustein konnte man damit Rechenwerke mit einer Breite von einem Vielfachen von 4 Bit zusammensetzen. Das Mikroprogrammsteuerwerk konnte mit einem Am2910 Prozessor aufgebaut werden. (de) El Am2901 es un microprocesador slice de 4 bits en tecnología bipolar Schottky. Diseñado para construir controladores de alta velocidad, con un número de bits múltiplo de cuatro. Contiene una ALU de 4 bits y 8 funciones, una unidad de desplazamiento independiente de la ALU (suma y desplazamiento sólo llevan un ciclo) y un array de 16 posiciones de 4 bits, utilizable como fuente y destino para la ALU. Posee 4 bits de estado. Funciona con una microinstrucción de 9 bits, dividida en tres grupos: Bits 8-6: Control de destino Bits 5-3: Función de la ALU Bits 2-0: Operando fuente (es) Am2900 è una famiglia di circuiti integrati creata nel 1975 da AMD. Sono stati costruiti con dispositivi bipolari e sono stati disegnati per essere utilizzati come componenti modulari ognuno rappresentante un aspetto differente della CPU di architettura . Per problemi complessi sono richiesti circuiti con parecchi Am2901, problemi più semplici sono risolvibili invece con l'utilizzo di una singola CPU. Il circuito integrato Am2901 rappresentava l'ALU, e il nucleo della serie. Il loro principale concorrente era l'economico Texas Instruments dotato di potenza molto minore. (it) Am2900 は、AMDが1975年に発売した集積回路（ICチップ）のファミリである。これらのICは、機能的にはビットスライス方式でプロセッサのセットを構成するものであり、プロセステクノロジはバイポーラトランジスタである。それぞれがコンピュータ制御装置 (CCU) の異なる側面を表すモジュラーコンポーネントとして使用できるように設計された。Am2900ファミリは、ビットスライス方式であるため、データ/アドレス/命令を4ビットの任意の倍数になるようにCCUを実装することができた。このモジュール方式の大きな欠点は、単一のCPU ICでできることを実装するために、より多くのICを必要とすることであった。Am2901チップは、演算論理ユニット(ALU)であり、シリーズのコアである。4ビットでカウントし、バイナリ操作やさまざまなビットシフト演算を実装していた。 (ja) A Am2900 é uma família de circuitos integrados (CI) criados em 1975 pela Advanced Micro Devices (AMD).
