    摘要: A device includes a number of memory cells. Each of the memory cells includes a transistor stack coupled to a bit line. A value of a charge on the bit line during an access mode represents a value of data stored in an accessed memory cell. During a non-access mode, all transistors of the transistor stack are turned off to save power. The transistors are turn off regardless of the value of the data stored in the memory cells.

    摘要: Embodiments of apparatuses and methods for multiplicand shifting in a linear systolic array modular multiplier are disclosed. In one embodiment, an apparatus includes two processing elements of a linear systolic array. One processing element includes multiplication logic, multiplicand shift logic, an adder, modulus logic, and modulus shift logic. The multiplication logic is to multiply a word of the multiplicand and a bit of the multiplier to generate a product. The multiplicand shift logic is to shift the word of the multiplicand. The adder is to add the product to a first running sum to generate a second running sum. The modulus logic is to conditionally add a word of a modulus and the second running sum. The modulus shift logic is to shift the word of the modulus. The next processing element includes logic to multiply the shifted word of the multiplicand and the next bit of the multiplier.

The system may further include determination of whether a least-significant bit of product Z is 1, addition of a least-significant w bits of modulus M to the least-significant w bits of product Z if the least-significant bit of product Z is 1, multiplication of the least-significant bit of X and bits 2w-1:w of Y to generate bits 2w-1:w of product Z, and addition of bits 2w-1:w of modulus M to bits 2w-1:w of product Z if the least-significant bit of product Z is 1. Multiplying the least-significant bit of X and bits 2w-1:w of Y may occur at least partially contemporaneously with multiplying the least-significant bit of X and the least-significant w bits of Y, determining if the least-significant bit of product Z is 1, and adding the least-significant w bits of modulus M to the least-significant w bits of product Z if the least-significant bit of product Z is 1.
